Scott, I worked at Beech in Experimental Flight Test while this program was being conducted. While I was not on this program myself, I daily observed it and discussed it with the engineers and test pilots involved (in the original film on KZbin I recognized many people I knew). While I am remembering back 45 years and the memory isn't what it used to be, a few pertinent things I remember: 1. The test program was driven by the requirement to recover in 2 turns or less from a 6-turn spin from standard and aggravated entries. 2. Opposite aileron during the entry was a carryover from the required spin entry technique for the model 77 Skipper. If aileron is not used on a Skipper, standard entry technique results in a steep spiral, not a spin. 3. Standard recovery technique (power idle, ailerons neutral, rudder against the spin and aft stick until rotation stops) was positive but borderline on recovering from the fully-developed spin in the required 2 turns. I recall it taking between 2 and 2 1/4 turns, but my memory is a little foggy on that - I do remember it hovering around 2 turns give or take. CG position may have been a player. NASA recommended trying aileron with the spin to recover in addition to the standard technique. It made the aircraft recover about 1/4 turn faster, which would have satisfied the requirement. I was taking my own multiengine training in a Dutchess about the time this program was finishing, and it was very comforting to me to know that the Dutchess would respond to standard spin prevent and standard spin recovery techniques and would not enter a locked-in flat spin - at least NASA and Beech Flight Test could not find a flat spin mode.

Thanks for the input Tom. Great stuff!

[@igclapp]

Thanks, Tom. Really interesting. But did you mean forward stick instead of aft stick for spin recovery? And does the NASA recommendation for "aileron with the spin" mean moving the stick towards the spin or away from the spin?

[@flybouy11]

Do not have an AFT CG.

[@tomblack9401]

@@igclapp Aft stick until the rotation stops THEN forward stick to break the stall. Aileron goes in the "cross-control" direction, i.e., if you are in a right spin use left rudder and right aileron. Standard technique for jet fighters of the F-100 - F-4 vintage.

[@tomblack9401]

@@flybouy11 Not sure what you mean by that. I mention it because as cg moves aft it is common for spins to get flatter and recoveries to take longer.

[@jackoneil3933]

Thanks for the excellent points Scott! What your relate about moments of inertia, pro-spin inputs and differences in aircraft such as T-Tail designs, is something that while a focus of attention in GA during the 80's seems to have dissipated from the flying consciousness and sorely needs to be brought fourth. What you relate helps to make sense of of personal near fatal experiences in twins, one of which I shared in the comments of one of your previous tuffted F33 spin videos, about a Bi-Annual Flight Review I had in a B55 involving a high-time CFI-MEI with zero time in Barons, who insisted on me demonstrating a VMC recovery, where my the heel of my right food became restricted by the sheet-metal cover below the rudders pedals and I was unable to add full rudder deflection, and the CFI abruptly stomping full right rudder with his #12 causing an abrupt yaw and what we later deemed to be loss of airflow over the vertical stab that ended up in an inverted roll and spin that without both of us having aerobatic training, we likely would not have recovered from. From a higher altitude we explored abrupt rudder inputs near VMC and found what appeared to be the ability to induce a sudden loss of rudder control with large rudder inputs and lateral inertial moment coupling. We later cautiously tried the same near VMC rapid rudder inputs In his straight tail Cessna C-310 which I sold to him (N666T) and observed no such tendency as the B55, and we speculated that the taller straight V-Stab on the 310 combined with the huge inertial mass of the 310's tip tanks and less tapered wing might have reduced what the Baron exhibited, however we speculated that the larger lateral inertial moment of those 310 tip tanks might make actual spin recovery in the 310 less likely then the B55. What you relate Scott about a "Thin triangle" of the B55's rudder being all you have available for spin recovery against a huge amount of inertial moment might also have something to do with what we observed in the B55 vs. the 310. The only other twin-spin experience I inadvertently encountered relates strongly to what you point out about inertial moments, pro-spin inputs and deep stalls, in an early (5th production Ser#) Cessna 337, on a sales-demo flight where I allowed an ATP to fly from the left seat who wanted to explore stalls, and he did so unaware he had left about 60% power on the rear engine, which being in a pusher configuration produced some right yaw (ball to the right), at which point I said: "You better step on that ball before you stall this thing". At which point he applied a lot of right rudder and hogged back on the yoke, and as the right wing dropped he applied full left-aileron, and then full up-elevator, and with full right rudder and left aileron applied,froze solid on the controls and throttles as we rolled inverted and his 300lb ATP buddy in the back who removed is seat belt after takeoff fell against the headliner yelling and kicking me in the back of the head. I manage to wrestle the controls away and recover into a vertical dive (I observed that at in a vertical dive the 337 produces enough drag to not accelerate very fast after about 230mph indicated) and was barely able to recover after catching a couple of accelerated stalls just above treetop level from what started about 4500agl. Everything Scott, you explain about inertial moments, pro-spin inputs and deep stalls we learned and survived in the 337 that day. The 337 has two heavy engines, at each end of the fuselage creating a very centered CG, and a long wing with 120 to 140 gals of span-wise fuel, and a huge elevator that can produce a very deep stall and some thrilling if not fatal stall-spin adventures . Later, when I bought a Twin-Comanche, I enlisted Carl, a CFI-MEI who had done some FAA re-certification flight tests for the Twin-Comanche that resulted in major increase to the Twin-Comanche's VMC and operational changes, had also done some spin testing as a certification test pilot, and what he impressed was to maintain keen Yaw awareness, and how lowering angle of attack on first detection of yaw deviation can be your quickest and most effective spin and VMC loss of control defense. In a Mooney and later in a single engine Comanchen 250, I was using to practice for the ATP (As I didn't have a twin at the time), Carl simulated VMC recovery in a single by setting up power-on approach to stalls in a cross-controlled condition, thereby practicing, recognizing and recovering from yaw deviation by lowering the nose and reducing power to stop the yaw divergence. I found that training a big awareness booster, and from then on strove to maintain acute awareness of yaw deviations and preventing them before they result in loss of control. That awareness is something that can be developed in single engine aircraft that can translate into twin engine survival as well. I may have mentioned previously Scott, that if awareness, recognition and avoidance of stall-spin/VMC loss of control should be more strongly emphasized in addition to recovery awareness and practice to as back in the 80's to address a rash of Twin-spin incidents.

That spin at 2:44 was really disturbing. That is usually the last moments that pilot will see in his life! Really appreciate the comments that say that the best thing is NOT to get into the position of flying craft into a perilous state.

[@Joe_Not_A_Fed]

My hope is that these videos scare pilots into keeping their twins far away from the spin region. Even a 172 can lose a thousand feet in a spin before recovery...which is a good reason to teach spins in a Skyhawk. I mean, if a Skyhawk loses that much altitude, their twin is basically a lawn dart in comparison. I think it might be an effective eye opener. Edit to say, thanks for sharing.

[@locustvalleystring]

Well done! I like that "pro-spin" analysis of control inputs. Most things you can do encourage the spin. Very sensible. As a side note, back in the late 1980's and through the 1990's I used to place 20 or so tell-tales with tape and yarn on the left wing during instructional flights to demonstrate the breakdown of airflow from the root out to the tip. Nothing like seeing the airflow breaking down.

[@FlyWirescottperdue]

All these videos on light twins tell me one thing and one thing only, light twins are the most dangerous airplane one can fly. If you lose an engine in a critical phase of flight your reflexes better be on point to get the nose down and crash straight ahead otherwise you have no chance, not to mention how dangerous training is in these airplanes where one mistake can easily kill you. Not even sure I want the ME rating anymore, I rather have that one engine and a crappy glider if it quits than illusions of maybe being able to keep flying and trap myself due to a small mistake.

When I was flying the Yak52 I took the time to fly down to Halfpenny Green (UK) not far from my base airfield to get flat spin recovery training with Yak 52 aerobatic exponent Gennedy Elfimof (Mr. Yak). It was a privilege to fly with him and we did several flat spins and recoveries in our Yak52. It was quite a few years ago but I remember spin entry was as for a normal spin but power on and out-spin aileron. The sensation of the world spinning horizontally around us took some getting used to. Recovery was [power off, in spin aileron, out spin rudder, full forward stick ALL APPLIED AT THE SAME TIME] until the spin stopped. So the stick was pushed hard into the relevant top corner, left top corner or right top corner, with opposite rudder, as the power was pulled right back. Then centralise and recover from the dive. (Caveat - this isn't flight instruction - consult your flight instructor for that) Vince

[@gonflying]

So to be clear, you're saying in a spin to the left, recovery is, full right rudder, stick full forward and left?

[@gzk6nk]

@@gonflying Correct - in-spin aileron.

[@trickedouttech321]

I agree, that training for spin prevention is best practice and if you own any plane, especially a twin you should never get close to the spin with a loss of engine because you have trained for it. However, if you ever do get into a spin in a twin, your spin-prevent training will not do a damn thing for you. At that point, if you have not trained for spin recovery in a twin you are dead. you don't have to spin your pane to train for it. you can sit on the ground and go through the motions over and over and over. If you don't know what to do once the spin you trained so hard to prevent starts you have nothing. Spin prevention is best practice but spin recovery is also best practice. When you get into a bad situation that you have trained to stay away from, this is called an accident, at this point just like a race car driver once the spin starts if not trained to recover your odds are very low.

[@georgehaeh4856]

If your altitude is less than what your aircraft uses up in a spin recovery, the ground will get in the way.

Hi Scott. I was on that chat and learned a lot even though I am not even flying right now.

[@sunnydayrcpilot]

Good discussion Scott. Imo the recent multi engine spins from VMC demos should have the FAA rewrite the ACS to delete the requirement for full rudder in the demo. Commonly the instructor or examiner in the right seat guards the rudders with their feet which is the safe thing to do but if the ACS made this technique a requirement safety would be enhanced. Seems to me half rudder travel is enough during the demo it still proves the point to the student.

[@John-nc4bl]

Remember, smooth moves on the rudder pedals. It is bad to violently slam the pedals hard against the stops as some of the welds or rudder linkages or ruddern horn parts can break. One of the worst cases that I can think of is the AA A300 that was on the climb-out from La Guardia and encountered strong wake turbulence. The FO slammed the rudder pedals so hard in either direction that the fin and rudder departed and doomed the big bird. So, smooth moves on those rudder pedals.

[@FlyWirescottperdue]

And it was his mistake to walk the rudder, don't know where he got that but it wasn't in training at AA!

[@philipcobbin3172]

This sounds on radius of gyration. If you spin 10 pounds at 1 foot moment arm, it's going to take more counter torque to stop a 10 pound weight at 2 feet. I can see where the rudder has a fixed moment arm and torque potential and with large weights either on the wing or on the fuselage center line outside the spin axis they can combine....fuselage and wing mass elements and "over power" the authority of the rudder, and or severely limit (slow down) any ability to arrest the rotation about the Z axis. I love you videos on this stuff. Thx.

[@txkflier]

With radio controlled model airplanes, I typically spin them using full rudder deflection, full up elevator, and neutral ailerons. To change the spin to a flat spin, I add power and move the aileron stick in the opposite direction to the rudder. To exit the flat spin, I move the aileron stick in the same direction as the rudder which makes the plane go from looking like a falling maple seed to a combination of autorotating and rolling. Neutralizing the elevator lowers the nose, allows opposite rudder to stop the autorotation, and the plane enters a rolling dive until the ailerons are neutralized. Then, up elevator is applied to pull out of the dive.

[@dermick]

@@spdaltidVertical wind tunnel a la indoor sky diving. Yes, the Reynolds numbers are different, but the principles are the same.

I asked multiple times if this was safe and why we were doing it if the FAA did not state it as a standard. Of course he was almost 70 yo so you can imagine how that conversation went.

[@jackoneil3933]

Something else Scott, I just recalled that might be worth mentioning from the 80's twin-spin era, was an article in Flying, AOPA Pilot or the old Aviation Consumer magazines, was a story a civilian CFI and former military test pilot related about getting into a spin, I seem to recall in a Baron or possibly Aerostar or Seminole that was not responding to recovery inputs after several turns, as a last ditch effort he was instructed in the military to apply alternate elevator up and down applications on nose up and down points of the spin, and was able to recover into a vertical dive and recover, but I've forgotten at which points he applied the inputs and details of the effects and why. Perhaps that might be something to cover.

[@jackoneil3933]

@@brandyballoon Yes, but I seem to recall the inputs he described applying might have been counter-intuitive at first. I had a spin experience in a Baron that was more a loss of vert-stab rather than stalled spin, and also an inverted spin an ATP put a Cessna 337 I was demoing into (described here) and after that I also wondered if extending the gear and flaps would help in spin recovery and my hunch is that the extra drag of nose gear and doors alone should counter a bit yaw moment, plus give a bit of nose-down moment, and help reduce acceleration in a vertical dive during recovery. I would think the same for flaps except it would lower your structural limits which could be an issue in a high-speed dive recovery, but if it had a chance of helping recover from a spin I'd be inclined to drop the flaps and gear as a Hail-Mary. One might have to be mentally prepared to do that. One thing I discussed with a couple of test pilots, was use of asymmetric thrust on the in-spin engine, one said it would likely increase the spin rate or flip you inverted, the other who had done spin testing in twins said that asymmetric thrust might be something he would try if all else failed, but as most spins, epically in twins happen a few hundred feet above the ground that it's best to train and be mentally prepared to avoid a spin the first place.

Thinking about primary instruction 35 years ago when I was teaching in the C-310, I did get into a stall prior to yaw in a VMC demo once. As the airplane started to roll 90° I maintained full rudder pushed the yoke full forward and closed the throttle. We recovered in a vertical dive and then smoothly recovered from that. We were at 5000’ on a warm spring morning and apparently the chart lied about where the stall/VMC line came together. Very dangerous situation we are putting all our kids through to get them trained. I think we need to ensure the operating engine is at full power and block the rudder with your foot so you get the yaw early for the demo recovery. That way you don’t get slow enough to stall before the yaw. Let me know what you think.

@@grumpy3543 I agree. It seems counter-intuitive to me. It's all very well spinning a plane that's rated for spins in order to teach spin recovery, but intentionally taking a plane that may not even be able to recover from a spin very close to entering a spin seems like a good way to get a Darwin award. Also, most if not all of the recent accidents have had passengers in the back seats. An aft CG makes spin recovery harder, if not impossible. Perhaps if this kind of training does continue, it should at least be prohibited to have passengers.

While learning aerobatics if found that if a flat spin is developed the best way to get out of it (for the aircraft I was flying) was to turn into the rotation and turn that flat spin into a traditional spin.

@@deanmccormick8070 And no mass items on the wings like a Baron or the Duchess. Your point is.....?

[@deanmccormick8070]

@@FlyWirescottperdue Point is that with mass of engines closer to centerline, there is less rotational momentum than with engines further out, as in a conventional civilian light twin. So that makes recovery easier and quicker. Also, iirc, there was a fuel limitation for intentional entries. T-37 has a center tank fed by wing tanks. So fuel limitation means less mass outboard to add that rotational momentum once the yawing has begun.

The PA38 does nice spins,

[@leedaero]

I took an aerobatics course in a CAP-10. To enter a FLAT spin from a normal left spin we raised the left wing with right aileron and added power to raise the nose. It would spin flat like a frisbee. Adding or reducing power would speed up or slow down the spin rate. To return to a normal spin it was the opposite. Left aileron to lower the wing and reduce power to idle to lower the nose. Fortunately the CAP-10 has a giant rudder. So would doing the same thing in a spinning twin be helpful, aileron into the spin whether it was flat or not?

[@FlyWirescottperdue]

Watch the video... and recovery depends on having something to stop the auto-rotational moment. The Baron lacks that. The Duchess, with the right protocol does. BUT NOT WELL ENOUGH FOR BEECH TO SAY IT IS CAPABLE OF SPINNING.

[@EllipsisAircraft]

The CAP-10 not only has a large rudder, but a lot of rudder area below and behind the horizontal stabilizer.

[@FlyWirescottperdue]

In the video I talk about In-Spin aileron. You cannot recover from a flat spin without reducing the pro-spin inputs... power, out-spin aileron, forward stick. Bug rudders are nice, the engineers that designed the Cap 10 did a good job of understanding the requirements.

Forgive me for this dumb question, I am merely an aviation meteorologist. What impact would lowering the gear have on the spin? In my Piper Arrow, it causes a strong nose up attitude adjustment. Would that have an impact on the spin?

[@dermick]

That's a really good question - at first glance it sure seems like it could help in a spin due to the anti-spin drag, particularly with the nose wheel, but it also moves some mass out with most aircraft, so that might be pro-spin. Then again, you've seen ice skaters that spin slower when moving mass out - like their arms. It would be interesting to know if the manufacturers have tested this.

[@FlyWirescottperdue]

Not to my knowledge.

[@FlyWirescottperdue]

Exactly what the reaction would be actually depends on the gear design and the airplane. Without a spin recovery chute, I won't try it.

[@j.w.perkins6004]

Spin recovery IMHO, should begin in private pilot training . Spin recognition & cause should be part of the syllabus. I can't imagine what i would have thought if I had inadvertently entered a spin with no instruction. I just happened to have some some instructions from the great Artie Scholl, while a private pilot.

You could probably break the flat spin of most planes by deploying a drogue chute from the tail section so that the plane starts diving vertical, then detatch the chute for flight-control recovery. Of course it would probably only be an option from the factory where you could get a full airframe chute anyway, making it kind of pointless.

[@tylerfb1]

I don't really understand what you're saying. I feel like I missed something, like this video is a part of a series. In that spin video of the Baron, I see the elevator and ailerons go neutral, then a recovery. Is that what you were saying? That aileron into the spin and back elevator are pro-spin inputs? On a different note, Ron White tells a joke long ago where he was on a smaller twin when one of the engines quit. The passenger next to him, scared, asked how far he thought that good engine would carry them. Ron's answer was probably more apropos than he knew: to the scene of the crash.

[@FlyWirescottperdue]

This video is indeed part of a series of videos on Spins I have done to cast light on what is happening in a very confusing time. It's complicated. The Test protocol they used for this Duchess, it was not a Baron, was to initiate the spin with In-Spin Aileron. The elevator was full aft. To stall an airplane you need stall and then yaw. During an intentional Spin, the full aft elevator is needed to stall the wings. At the stall left rudder is pressed to introduce yaw. The protocol had the left aileron fully deflected up at the stall. The interesting thing is that presents adverse yaw.... Left aileron up introduces yaw adverse to the left roll... the yaw is to the right. Which is counter to a normal spin entry, it is in fact anti-spin. When the Spin is developed, during the 2nd or 3rd turn, That In-Spin aileron is no Pro-Roll and it still produces adverse yaw. but the rolling input allows the nose to drop enough to change the relative wind over the rudder so that it becomes effective in stopping the yaw (with a little anit-spin adverse yaw from the left aileron up). So, to strictly answer your questions- In-Spin aileron is pro-roll, anti-spin, the elevator is what allows the stall/spin to be triggered, so in a way up elevator is pro-spin. But not as effective Pro-Spin as full forward stick.

[@tylerfb1]

Regarding the 3K to recover from spin then add altitude loss for dive recovery, Sammy Mason has an interesting point, as low as survivability is in a flat spin, you may want to drive it flat if you cannot get out, as this is slower and more survivable than steep. In the case of the wing loaded aircraft, outside pro-spin power, pro-spin yaw, stick aft, and aileron into the spin will help drive it flat.

[@FlyWirescottperdue]

Stick forward is how you make it flat. I don’t know of anyone who has survived a flat spin impact. Do you? A good friend died in a flat spin.

[@jimallen8186]

@@FlyWirescottperdue forward stick accelerates (ice skater), it only flattens should this acceleration provide sufficient centrifugal that aero cannot hold it. Meanwhile, forward stick will have differing effects to roll and yaw depending on wing or fuselage dominant loading. In some platforms, forward stick could push you through from erect to inverted. If you’re going to hit, would you rather hit faster? “Do I know…” is anecdotal hence logical fallacy in the argument. As for Sammy, he was a Lockheed test pilot, I think I’ll give his view some credit.

Non-pilot here..... while I understand this is an important topic, it does give me pause when I think about getting a pilot license. I understand many manuals have a chart/graph showing dangerous areas of the flight envelope where you could get into a spin. Modern glass instrumentation in today's planes should have all the needed data that they could apply to this chart/graph to give you a real-time update on just where you are in the flight envelope. Could this computer watch over your flying data and tell you when you are approaching the danger zone of a spin? I have been hearing a number of stories recently where young pilots are doing their multi-engine training with a view of a career in commercial aviation. It seems every few months I read of another training pilot spinning his light twin into the ground. Could the modern computers keep watch over these situations and keep training pilots out of the danger zone?

[@FlyWirescottperdue]

Possibly. It’s a matter of cost. That technology worked in the F15E.

I have a perspective - sad that it may be - that the training is required to ensure the individual has the mental horsepower to handle the inputs and take the right decisions. Professional pilots are a rare breed for a reason, they have to be exceptional.

[@scottboelke4391]

In the prowler they gave us a switch to get more elevator pull in the spin. It was important to get air back over the rudder. They also gave us a yaw rate indicator. If you waited until rotation stopped, to neutralize rudder and stick forward, it was too late, it'd flop to the other direction. Someone should do a vid on prowler spinning.

Perhaps I'm missing something. Is there an article or something written that clearly lays out what Beech did to recover the Duchess? The video titled "Twin Spin Testing Beechcraft Twin Video" says nothing about what you are talking about. They kept pro spin controls applied until they wanted to recover. That includes FULL AFT stick or elevator up which normally, at least in GA airplanes that is a pro spin input. They also said that they recovered using standard spin recovery techniques which is power idle, alerions neutral, rudder in the opposite direction of the spin, and FORWARD stick to break the stall (if needed). I feel like there is at best missing context and at worst incorrect information.

[@FlyWirescottperdue]

Y o u are wrong about that. I preach full aft elevator and show that in my videos. It is not a recovery step it is a stabilizing step. I talked in this video about what they did. Sorry you missed it. Go get a copy of Aerodynamics for Naval Aviators, turn to page 311 and read the right hand column. The stuff you think you know is wrong.

[@garrettferguson449]

The spin recovery of the modern high speed airplane involves principles which are similar to those of the spin recovery of the conventional airplane. However, the nature of the spin for the modern configuration may involve specific differences in technique necessary to reduce the sideslip and angle of attack. The use of opposite rudder to control the sideslip and effect recovery will depend on the effectiveness of the rudder when the airplane is in the spin. At high positive angles of attack and high sideslip the rudder effectiveness may be reduced and additional anti-spin moments must be provided for rapid recovery. The deflection of ailerons into the spin reduces the autorotation rolling moment and can produce adverse yaw to aid the rudder yawing moment in effecting recovery. There may be many other specific differences in the technique necessary to effect spin recovery . The effectiveness of the rudder during recovery may be altered by the position of elevators or horizontal tail. Generally, full aft stick may be necessary during the initial phase of recovery to increase the effectiveness of the rudder. The use of power during the spin recovery of a propeller powered airplane may or may not aid recovery depending on the specific airplane and the particular nature of the slipstream effects. The use of power during the spin recovery of a jet powered airplane induces no significant or helpful flow but does offer the possibility of a severe compressor stall and adverse gyroscopic moments. Since the airplane is at high angle of attack and sideslip, the flow at the inlet may be very poor and the staI1 limits considerably reduced. These items serve to point out possible differences in technique required for various configurations. The spin recovery specific for each airplane is outlined in the pilot’s handbook and it is imperative that the specific technique be followed for successful recovery. My fellow brother in aviation the book is talking about swept wing aircraft. Not hershey bar winged twins. Also I think that last line is important as well.

[@mattj65816]

Only tangentially related, but all of the talk about yawing moments and twins lately has made me wonder. Can anyone tell me, in a twin jet with the engines way back on the tail, if one engine fails, does the nose of the airplane yaw toward the still-operating engine? Irrespective of any stability augmentation system the aircraft may have; based on sheer aerodynamics, balance, applied forces, etc., would an aircraft with a dead engine behind the CG yaw in the opposite direction of an aircraft with the same dead engine ahead of the CG? It seems like it would. The thrust asymmetry would result in a "local" yaw toward the dead engine, but since that local yaw is behind the CG, it would translate to yaw in the opposite direction at the nose...I think?

[@FlyWirescottperdue]

No. They yaw into the dead engine. I flew the 727, F100, DC9.

[@mustardseedsociety]

Scott - I totally believe everything you're saying so I'm not disputing anything. But my brain is having a hard time getting over some obstacles. Let's look at electrical power as an example. 12 volts and 10 amps = 120 watts. Likewise 120 volts and 1 amp = the same 120 watts. Energy is energy. Now let's apply that to an Olympic skater. The Olympic skater starts her final closing spiral with her arms held out and a relative slow rate of turns. Then she brings her arms in and the rotation speed increases giving her a rather impressive ending to the routine {and the crowd cheers LOL}. So the point is, since energy is neither created nor destroyed, it only changes form, her energy quantity should be the same just like in watts = amps X voltage in electricity. So now let's apply this to a spinning airplane. If the engines are on the wings, YES there's 2 each mass moments to deal with - HOWEVER the engines are attached to the aircraft just like a skater's arms are attached to her body. Since energy is energy, I'm having a hard time figuring out why it's more difficult to stop the airplane from spinning simply because the engines are on the wings. Wouldn't that result in a slower spin RATE just like the figure skater ?? Tell me what I'm missing - PLEASE. Thanks Scott !!

[@FlyWirescottperdue]

What you are talking about is called Conservation of Momentum. A skater spins about an axis that is coincident with the body, so we see the rotation purely in one axiss. An airplane with large mass moments in the wings has an axis through the airplane, and a spin axis and then another axis outside the airplane (it descends in a helical pattern, in the earth's frame of reference). This means that mass moments couple... instead of a reaction in one axis, you have reactions in two or more and that results in wild, unpredictable gyrations. The Auto Rotation Moment is what needs to be stopped. In an airplane with mass moments, removed from the spin axis, the result is pro-spin and the result is it is resistant to recovery inputs to stop the yaw. It's not a simple system like a Skater. By the way the electrical metaphor is a poor choice because of resistance in the circuit... that burns energy. Unless, of course you constructed the circuit out of a superconductor.

[@mustardseedsociety]

@@FlyWirescottperdue OK I {think ??} I get it. So basically what you're saying is the spin axis is different than the lateral, vertical, and longitudinal axis, which is why you place an emphasis on relative wind. Trying to understand this stuff is not that easy LOL. But thanks for the explanation. Yea also, I just realized one of my mistakes in my analogy is the airplane is falling to the earth gaining {or at least maintaining} energy, where as the skater will eventually run out of energy in about 3 seconds.

[@FlyWirescottperdue]

@@mustardseedsociety No worries, not to make it more complicated, but the falling airplane is just exchanging potential Energy for Kinetic Energy. Some energy in the equation is consumed by drag.

The "Airplane 101" guy just recently said in a podcast {somewhat paraphrasing here} "pound for pound, there is no better life saving equipment than BRS" - well he's the "Airplane 101 Guy" and he's more accomplished than me as far as piloting goes, so how about collectively "we" quit messing around and get these STC's out ??

Spin and a VMC roll should not be confused with one another. In a spin the wing is stalled. In a VMC roll the vertical stabilizer is stalled.

[@FlyWirescottperdue]

Yeah, I hear that, but I don't think this is true at all. In any spin there is 'roll', but it is really yaw with one wing dropping for various reasons. The roll and the yaw are coupled. We perceive it as roll, but it isn't. It is a spin, and the power is pro-spin. I think you are searching for an explanation with this notion that a vertical stabilizer stall as the cause. See my Tufted Wing spin video.... the Vertical does not stall by itself. In a departure the wing and the inside vertical stall at the same time. It's more complicated than you suggest.

[@fliteshare]

@@FlyWirescottperdue Well the real problem is in the recovery. The recovery of a spin is to FIRST stop the yaw by stepping on the rudder. Which in a VMC roll ain't gonna do anything because the vertical stabilizer (and rudder) are already stalled. The ONLY recovery for the VMC roll is POWER off, NOSE down. And because those recovery techniques are so different, the 2 shouldn't be confused with one another.

The effect of latetal control during spins is not intuitive and depends on the resultant moments of inertia.... precession. Lateral input isn't typically characterized as 'pro roll' or not, rather it is 'pro spin' or 'anti-spin'. Assuming lateral input acts conventionally, the effect of lateral inputs are determined by moments of inertia, B (Iyy) and A (Ixx) from the eq of motion. Typically, 'in-spin' lateral inputs on high B on A aircraft, like the F15 and F111, will result in an antispin effect, whereas on low B on A, ratios less than 1.3, can have a pro spin effect. Furthermore, the helix axis path of a spin is typically outside of the aircraft. The rotational motion of the aircraft is always about the aircraft CG. Generally, forward stick is always considered anti-spin, excluding local aerodynamic effects, eg blanking due to alpha which may be particular to an aircraft type. In terms of precession, it has a restorative effect. Thats why you always release the back pressure from an induced spin. This is the opposite for inverted spins.

[@FlyWirescottperdue]

I could track with you fairly well with some issues up until your last sentence. The CG is only applicable in normal, forward flight. It is a sum of moments along roll axis. The effect of moving flight controls or power during a spin is a gyroscopic input, not precession.

[@rampy4963]

I totally agree with the premise of your video. Just adding some minor points. I meant to say the eq of motion reference frame that govern how the aircraft behaves is always about the CG. The CG translates down the helix path of the spin and the helix axis is genetally outside the aircraft. A piston/jet engine does have its own gyrospic effects, however control inputs are dictated by the eq of motion... precession and gyroscopic effects in this sense are one and the same, often called gyroscopic precession.
