Years ago, I had taken two people to a fly in lunch event. I made sure the plane was within limits, and even left a lot of fuel behind anticipating landing again in 19 miles to refuel with better runway conditions. This particular event attracted so many airplanes that when it was over, they had guys with flags waving the next plane onto the (grass) N/S runway for departure. And this is where things got weird. The wind was mostly favoring a southern departure (fluctuating cross-wind), but everyone was taking off to the north "as instructed" by the probably non-pilot flag men. It was an uncontrolled airport, and the north departure was also running uphill. As my passengers were busy doing what passengers do, I was sitting on a picnic table assessing everything that was going on here. I was flying an Archer, and there were other Cherokee products as well as a few 172's, all equally loaded in my opinion, successfully departing. I must have watched 30 or more planes take off. So, with the knowledge that I was within limits based on all available information I had, and having watched other airplanes depart, I elected to get in line. I back taxied to the very very end, making sure to grab every inch of runway, began the take off roll, got the nose wheel up and into ground effect, and then......NOTHING. I was past the point of no return, and the SOB would not climb. I was gaining altitude but the uphill runway under me was keeping pace. At the end of the runway, there were trees, covering the hill/mountain I was supposed to be climbing over. At the very last possible moment, just seconds before impact, I reached down and pulled in all the flaps. It was a last ditch attempt commanded by something deep in my mind, as opposed to a conscious and direct thought. I didn't think about it, I just DID IT. And I did this with such haste that I hit my knuckles on something (I still don't know what it was) and I had blood running down my hand and wrist. But it worked. The plane climbed the hill, with the trees just 4-5 feet below us all the way. Once I cleared the top, we flew out over a cliff and leveled off above the lake. Thirty some years later, I can still hear myself exhaling once I cleared the last of the trees. Throughout all of this, both my passengers were oblivious just thinking it was business as usual. I didn't discuss the near tragedy with them. I saw nothing to gain by doing that, but I took with me the most valuable lesson one could ever learn. Trust your gut. Something didn't feel right. On paper, we were "good to go", and yet there was that nagging little voice telling me to re-evaluate and change things up. Looking back, if I had not decided to go in empty and re-fuel 19 miles later, we'd have surely hit the trees. I don't fly anymore (medical issues) but the experience I garnered that day stayed with me for the rest of my flying days.

I'm curious what you mean by pulled in all the flaps? You went full flaps or zero flaps?

[@MrTONYTONYM]

Great analysis. Two things I find that are the most important to any pilots: 1. We teach students on High Density Altitude takeoff by simulating reduced thrust on piston aircraft, and make them aware of the performance reduction. However, they rarely get to experience the reduced lift over wings in actual high DA scenarios. 2. Slow flight is practiced over and over in flight training. We always preach "power for altitude, pitch for airspeed". However, this is always done at a sufficiently safe altitude and with partial power settings. The reality when you get out of ground effect too early is that you have no more additional power to play and no altitude to pitch down and gain airspeed.

[@PDZ1122]

This is not an analysis. He has no facts and is just guessing.

[@thisisyourcaptainspeaking]

They'll take their students onto a long runway, and then, rather than using full power, they'll take off with a reduced power setting to simulate a high altitude airport. An aircraft has reduced performance at high altitudes as the air is much thinner. Hope this helps.

I had a fun career in skydiving. Advanced the ranks quickly. Was invited to be a part of an Airshow 2 weeks after graduating AFF... felt great. I'd only been skydiving 6 weeks. I was getting accolades, picture on the cover of a regional brochure. I won an accuracy contest at that airshow. I jumped hard. Accumulated 3000+ jumps in a very few years. Never had any accidents or injuries. Being of scientific/mathematical mind, one day, out of the blue... I was done. No reason other than the visualization of probability in my head. Sold all my gear. Over the next 10-20 years, I slowly lost 4 skydiving friends, 2 who were my original AFF instructors to canopy collisions and aircraft accidents, one had pilot chute deploy on climb out, his body tearing off half of the C206 elevator.

Privately, you may fly/drive a million miles, but do it commercially and it all changes. You push yourself to the edge because you have expectations placed upon yourself and, of course, this affects your judgement, greatly. Very difficult to balance out.

I actually put a plane down on a back country strip in Alaska this past Friday . Did several fly-by’s and everything looked good. Did a touch on the next pass to test the surface and felt firm. Came in for the final landing and as soon as I dropped the flaps I felt the plane just bog down. I threw full throttle and pulled some flaps back in, but was still slowing down. I ran out of runway and just committed to the landing trying to keep from nosing over. Turns out there wasn’t much grass and it was a lot of muskeg which holds standing water just below the surface. I taxied to the end of the runway while configuring the plane for takeoff. I was nervous if I stopped completely I’d never get the plane back out. I made several attempts to takeoff and made it into low ground effect one time, but got lucky and recognized what was happening and aborted the takeoff instead of floating it into the trees at the end of the runway. Had to pay an atrocious amount of money to contract a chopper to sling load the plane out of there, but I’m uninjured and the plane is still undamaged so I simply chalk this up to an expensive learning experience

Flew Alaskan bush for over 20 years. In 1994, there were 15 fatalites of people i knew. Billy D., if you read this, I know that you remember that year, many were your friends. At the 3rd funeral, I got tired of hearing "a great pilot, I'd fly with him any time". I said to myself, "then why are we here. For 30 seconds they weren't". They made bad decisions. "Get there itis" was a major killer. In 2009, a dear friend was eager to get to his High School 40th reunion and ignored the weather briefing and flew his Lancair 4P into a Cat 5 thunderstorm. The wings and horizontal tail sections were torn off at 20,000 FT. I just pray that he was not conscious during the decent. Pushing the weather, overloaded aircraft, and game spotting were the primary causes of crashes and fatalities during my time while living in Alaska. All were based on the decisions made by the "Pilot in Command, (PIC)".

[@oscarb9139]

Coffin corner is a high altitude scenario. 30,000 feet and higher. As aircraft fly higher, the red line speed( barber pole) decreases, and the stall speed get closer together until they are very close together. There might be a spread of 15 to 20 knots between Vmo/Mmo, and Vstall at very high altitudes. If a stall occurs, loss of control occurs. If the aircraft is overspend, the center of lift can move aft, causing a nose down moment, further exacerbating the situation until the aircraft structure fails.

[@roymollenkamp991]

Yes, we are all aware of the technical definition and root of the term. It is being used here as a reference to a situation where you cannot go faster (cuz terrain) and cannot go slower (cuz stall). Thanks for the flex. You must be fun at parties.

It's nearly impossible for customers to accept judgement calls like that when surprised in the moment.

An early morning departure (just after first light) gives both improved aerodynamic & engine performance given the greater air density at that time. It assisted my C-182 take-off many years ago at Mount Hotham, Victora, Australia, when the grass strip was covered by overnight snow. After a warm water deice then a few runs up and down the strip to create channels in the snow to reduce friction on the wheels, I was ready to go.Once airbourne in the ground effect, it was time to accelerate to a safe climb speed then headed for home. The performance improvement was very noticeble with increased engine power, air mass flow from the prop and aerodynamic effects from the high density cold air.

[@avi8r66]

The main difference is that the culture of bush flying doesn't carry scales with them to weigh everything as it is loaded. If they flew in they can fly out, usually. But then you get hunters bagging 500+ pounds of meat or whatever and you have a situation of not being able to fly them out. A great pilot can get all the possible performance from the plane in the available conditions but physics is in charge. That pilot needs to stay within the limits applied at that field, they need to know the atmospheric conditions, exactly how much drag the runway will induce, height of the trees at the end, the wind speed and direction, and the weight of every object going into the plane and where it is positioned to be able to do a proper weight and balance on it. And then how much fuel is onboard, is the engine performing at it's rated levels, etc. In non bush flying this is much more commonly done, but in bush flying it's usually not done well when picking people up in the remote areas where they are being fetched from. Doing all these steps though removes most of the risk.

[@Triple_J.1]

[@adb012]

If there is a moderate slope and a mild wind, I would take off down-slope with a tailwind over up-hill with a headwind. Yes, you will need more ground speed which requires more runway length, but you also get more acceleration which requires less runway length. And even if it takes a little more runway, take-off run didn't seem to be limiting with a 4000ft runway. After you are airborne, you don't need to achieve a positive climb rate. You can just remain level gaining speed and let the terrain descend under you. Of course, it will depend on the magnitude of the slope and wind, and the best thing is to consult the airplane manual to calculate the required runway length for given wind and slope conditions and add your personal margins over it.

In most of these crashes engine failure on take off was the cause, and unfortunately the decision to make that turn lead to terrible crashes with many not surviving it.

i am struggling to understand how his low speed on take off could do so much damage to the aircraft. so sad to hear about Jim Tweto,

[@thisisyourcaptainspeaking]

He would be at full power and unable to climb as he would have entered the slow flight range (back side of the power curve). The airplane can't climb in this range as there isn't enough lift being produced over the wing. Thanks for watching!

One time I weighed a Chieftain for a 135 operator. He left his map case inside and some of the drawers in the furniture had some items inside them too. He was mad I weighed it that way. So, I asked him, "Do you take these items out before you fly?" He might have wanted a little extra "legal" load capacity, but he got a small margin of safety instead. Think about it.

It doesn't take much for pushing the weight to become a norm. Good call on your part. Thanks for watching!

[@jimmydulin928]

Experience is much more accurate than math in the art of flying, so some of us get really old before the exposure that comes with experience catches up with us. Getting out and into safer flying is a good old and sorta bold move, as with your going to the airlines. I was a crop duster when it was mostly with the 0-540 235 hp Lycoming in Pawnees and CallAirs. A ruptured dist and operation caused me to change to pipeline patrol that allowed me to fly longer I think. Ag now is mostly with 700 hp or better turboprop jet aircraft that cost enough to trigger a whole different concept of the business. I once bought a Stearman with a 450 hp P&W for $10,000 that, while a basket case, was pretty safe because the hopper (where the front pilot used to sit) would only hold 200 gal. Like bush, we could adjust the load based on experience and conditions. Having something you could always put 200 gallons in was like flying an airliner that you could expect to be able to go around on one engine with a full load. There are old, hard working, experienced pilots, who accept tough missions. Experience vs. exposure. Yes, there are few old bold pilots. Jim was one I think. Thanks for the report.

[@thisisyourcaptainspeaking]

I was old school as you say when I use to fly years ago and had some money to do so. But do msfs and FSX still. 1981 through around 1989. But safe and knew the Cessnas very well. Now on the Sim I fly all the way through props to airliners and gliders and such. It is sad the accident that took place for all involved. If you take off in a small field surrounded closely by trees, you have trapped air, and different wingtip vertices, which reduces the overall performance of any aircraft and as you say, makes Bush flying a whole different game. Maybe just 75 percent of full weight capacity in case of any hiccups in TO. Max load is noted in perfect conditions Smooth hard runway, etc.

I landed @Heber airport (5675 MSL). Upon landing I noticed the landing roll was a bit longer than anticipated and that my in flight fuel consumption was less than expected. Basically it was too hot to take off again with as much fuel as we had on board…my CFI and I had to recalculate for the current atmospheric conditions and determined that we’d have to wait another couple of hours for cooler temperatures before we could safely take off …we probably could have made it at the earliest time however both myself and my instructor thought it best just to wait…NOBODY EVER NEEDS TO FLY…get there itis is fatal damn near every time…patience is a life saver in aviation

[@tungstenkid2271]

Maybe the weight of the bear in the back messed up the centre of gravity? I think the optimum CG position for a straight-winged plane is between 25% and 31% back from the leading edge, and if its beyond those limits the handling suffers. PS Captain you mentioned bad ground effect in relation to your own experience, I always thought the GE "cushion" was a good thing to help planes lift off, so please clue us in about it a bit more..:)

[@thisisyourcaptainspeaking]

A shift in C of G could cause Jim to reduce power in order to keep his nose down. Though it's a small cabin, a bear would use up all the space. I couldn't climb out of ground effect. Definitely need ground effect to get airborne but at max weights on short strips, you may run out of runway before hitting the required speed to climb. Thanks for watching!

@@thisisyourcaptainspeaking Thanks, and the early Comet jet airliners ran off the end of the runways because they couldn't get out of ground effect.

Should make the take off w 3/4 weight see how it goes come around land and then add weight . Easier said then done I know , but a slightly underperforming engine is hard to notice sometimes but it can really make a difference in take off climb. Or your just over weight for the field but if you TO 3/4 weight you have a better idea of the performance of that field on that day and what’s a go around in the pattern take ? 10 min or less to save your life. I’ve seen it first hand an airplane on the edge of being overweight for the field can diminish in abilities from a very small amount of added weight. 5 knots coming out of ground effect can make a huge difference too. Once you behind that curve your causing more drag making a bad situation worse.

I had something similar - one brake dragging, so compensating, cruise prop, very hot day, heavy passenger.......sagged back to ground when I tried to lift off; trees/power lines ahead; eventually got her flying and STAYED in ground effect to try an eke out a bit more speed - over the trees, stuffed nose down; more ground effect; up over next trees, diito, then finally enough speed to climb.

[@warren5699]

'It's the propeller holding you in the air not the wind over the wings'? A Skyhawk at max thrust is creating about a 500lb force on the thrust line and on the climb at about a 10° pitch, what's that contributing to total lift - probably about 5%. In a more powerful airplane, sure, you have more climb performance, but it still requires the pilot to manage the pitch so that Vx is maintained. The back side of the power curve means that the drag is higher the slower the airspeed. It does not mean power can control altitude, and that can I think get you into a very tough position if you don't control the pitch to accelerate to Vx. I'm not saying that's what happened - just discussing any airplane's performance characteristics.

[@thisisyourcaptainspeaking]

My best guess is he ended up on the backside of the curve and didn't have altitude to give up. May have had engine trouble but we're still lacking details. Regarding my comments; yes, the wing is still flying but as the laminar flow becomes more and more disrupted, the power needs to be increased; hence the prop is keeping the a/c in the sky. Thanks for watching.

[@warren5699]

@@thisisyourcaptainspeaking Well what I read in the manual is that increasing angle of attack raises induced drag requiring more power to maintain speed. That keeps the wing moving fast enough through the air so that it can continue to maintain the opposing force to the weight.

[@thegreatdominion949]

Why didn't Jim use a more powerful plane for jobs where it was clear that the performance of his Cessna 180 would be marginal at best? Do you think ERA might face legal repercussions if it is determined that his aircraft wasn't being operated in a safe manner (i.e. overloaded)? I also wonder what you think of his practices as shown on the TV show of having his clients throw out items of cargo to reduce the landing weight of his aircraft. Is that an acceptable practice in Alaska? I can't imagine it would be in many jurisdictions.

The C-180 is a great plane to use for this type of work. Further information was released regarding the crash and I'm working on an additional video as a follow up. I'm sure the legal component will be a messy one.

Weight, altitude, performance, strip condition etc. We brief our performance on two main criteria (assuming we've loaded to the max TO weight as per our perf charts for each strip), an Acceleration Check Point and a Safe Abort Point. Our Accel check point is minimum of 70% of our rotate speed BY 50% of expected GROUND roll.

Ultralights are my recommendation for major fun with minimal danger. They stall at such low airspeed your survivability in a crash (assuming you still have some control to pick your spot) is almost guaranteed. I know a fellow who's engine packed it in at several thousand feet. He had a clearing ahead to the right and another ahead to the left. He chose the left one for a dead stick landing. Unfortunately when he got to a point where he was committed he realized the clearing was all tree stumps. He glided in over top of them then banked hard left and planted the aircraft with one wing up on a tree and one on the ground. Completely painless except for the damage to his machine.

Overloaded craft is common, violating accepted standards is more the norm than not...when you fly seatfare and even sometimes on charter. I always preferred using state pilots...they have no incentive ro fly because they get paid on the ground as well as in the air.

I encountered it once with my father on a one way in and one way out hillside grass strip - a short one, with a tree lined valley on the approach/exit and a hot summer's day. Dad in the left seat, lots of hours, but in a C150, two up, down hill, poor lift (slight change in wind direction and very hot, although early evening iirc), we got into that ground effect scenario, stall warning screaming etc as we were flying on the prop. We crawled over the tree line at the far end, after we'd flown up the valley level with the trees etc. I don't suppose we were the first or the last, but it was a sweaty palms job AND my dad was a good short/soft strip pilot (of course C150s are often good at getting into places with 40° of flap but struggle to get out again), even so, it caught us unawares. In hindsight dad should probably have flown out and I should have met him via road at another airfield ten miles or so away (by getting a car ride). But we thought all would be well, but a slight change in wind direction made it difficult. Lesson learnt😲😱✌️👍💜

So he goes hunting Caribou with his boys and they try a take off with a load of meat and on the frozen lake it could not get in the air before the end of the lake. The last attempt he was not going to pull the throttle back, the plane staggered into the air in ground effect but couldn't clear the shore at the end of the lake...plane was repaired and but was never the same beautiful airplane it had been before the crash, wrong people repaired it.

If you have not reached 71% of rotation speed by 50% of the runway, you should abort the takeoff.....you won't be able to reach enough speed for safe climbout. I like to walk the runway off and put a branch or paper cup along the side ot the runway at the 50% point. When I get there, I'll know if I am gaining enough speed for safe departure. In general, you are better taking off downhill into the wind than uphaill with the wind unless the wind is blowing 20 - 25 knots uphill Get Sparky Imeson's Montain Flying Bible for more detailed explanation of ths. The "71% Rule" works on any runway surface and at any DA, field elevation, surface wind speed, or with any aircraft.

[@pcpolice7937]

So, on a 10,000 ft runway, if you don’t have 71% of rotation speeds by the 5,000 ft mark, you should abort or continue if you do? That’s just a stupid statement. If you use this “rule” you would take off at the VERY END of the runway. You should calculate the take off distance for your aircraft from your pilot operating handbook for the existing conditions and weight of the aircraft, add a safety factor and then add your minimum stopping distance. (Also in the POH as landing distance.) Then make sure you have enough runway to do so. I know very few pilots that take off uphill with the wind. And 20-25 knots is even worse! I call BS that you are a pilot at all!

[@igclapp]

​@@pcpolice7937It's even worse than that. The 70% number assumes constant acceleration (in which case distance travelled is proportional to the square of speed attained). A prop produces less thrust as airspeed increases. You also have increasing drag from the wheels spinning faster and more parasitic drag at higher airspeed. So acceleration is actually decreasing during the takeoff roll and you probably wouldn't even be at flying speed by the end of the runway. And if it takes you 10,000 feet to attain takeoff speed in a light aircraft, good luck having enough excess power to even climb out of ground effect.
