Taming the Twin: Four Rules for Safe Multiengine Flying

[@jordanryan5064]

Maybe the CFI should have just landed on the student's street to shorten the drive home. I mean seriously, you can turn off the runway with no engine power at all, just coasting.

[@stevemagnuson7051]

Rule #1 in Multi-Engine flying is to always assume you are going to have an engine failure on takeoff. Rule #2 know your engine out procedures cold. Rule#3 Brief every takeoff, what you will to in the event of an engine failure. Rule#4 don’t get complacent

I'm about to check my PP license. One of my instructors, great guy, younger than me, had just quit his job in the flight school to flight executive on a Piper Cheyenne. Less then a month ago he was doing a night flight over the ocean and crashed. All three occupants died. I don't think we'll ever know what really happen, but what we do know is that his last communication reported the loss of one of the engines... Having two is not always a guarantee. Maybe you won't be able to keep your altitude, maybe it will throw off your stability in the longitudinal axis, maybe it will give you a false sense of security, then you'll think you can maintain a certain attitude because of the remaining engine, but you can't and a stall will ensue. That accident was a real tragedy and very traumatic to everyone who knew him. Thank for this video. Let's all focus on safety procedures and study, really drill them. Let's not take anything for granted, no matter what equipment we're flying. I don't know what happened to my friend, maybe it was absolutely inevitable, but let's avoid every accident that can be avoided in the future.

Great video. Study, plan and fly safe. I've flown Cubs on floats, DC-3s, T-38s and C-141s before the Boeing line with Delta. Leading large formations of jets, flying special ops low level on the goggles and flying light twins single pilot at night or in the weather were the biggest challenges of my career. At this stage of the game I'd rather fly a highly automated B777 single pilot than a C310 or Aztec in the weather at night. I'm not diminishing the essential role of the F/O (many have saved my bacon) but stressing the workload as a single pilot. Be safe and have fun.

[@joaquinfabrega]

My father was flying his Commander 500, between Cozumel and Miami we lost one engine, the plane flew without a problem. On the other hand, my uncle lost one engine in a C 310, crashed and die. At the end I learned that there are differences in plane performance, many factors will affect the way a twin flies without an engine. However, I always keep in the back of my mind that in a single you are always a step of an emergency while in a twin is a matter of stretching the hard landing.

[@MrSuzuki1187]

The huge omission in this video is the most important one for pilots of light twins. Pilots must memorize and then practice the 9 basic immediate action items that need to be done quickly and accurately should an engine fail close to the ground on takeoff or go around. Since the airplane will not climb, or might even be descending, there is no time to read a checklists. Here is what must be done and done quickly: 1. Mixtures, prop and throttles full forward 2. Pitch up to climb attitude 3. gear up ( do NOT wait for a positive climb as most light twins will not climb on one engine gear down) 4. Flaps up 5. Identify (dead foot, dead engine) 6. Verify (slowly retard suspect throttle. If no change in rudder use, the failed engine is verified) 8. Prop failed engine full aft 8. Mixture cut off 9. Prop feather. (These 9 items need to be practiced often until they can be done in one’s sleep.) Establish climb at Vyse, bank 3-5 degrees toward good engine and apply rudder so that the ball is 1/2 ball off center toward the good engine. To remember which which wing to raise, the gouge is “raise the dead”, as in raise the wing of the dead engine. REAL multi-engine instructors would have said all of this in the video, which was long on theory, but short on real useable information for the multi-engine pilot. Joel Turpin.

Thanks for informative comment. I'll never be a ME pilot (age, $$) but find your check list illuminating. Always pays-off to train to be a better pilot.

[@RedHawk785]

Precisely. You have succinctly described the nine steps that must be followed on every such occasion and by instinct through intensive training. From what I've read an engine-out on takeoff was the major non-combat cause of fatalities for P-38 pilots. The plane would flip over and auger-in in the blink of an eye if the rotation speed was incorrect. It even happened fairly recently to a civilian P-38 non-owner pilot who flew warbirds as an aviation journalist and had a special attachment to the P-38 due to his father flying one during WW2. Very ironically and sadly he was the now-deceased pilot who gave me the information about the cause of the majority of non-combat fatalities of military pilots flying P-38s. But it happens to airline pilots too, an example being 42 fatalities in the engine-out crash on takeoff of the TransAsia Airlines ATR where the PIC mistakenly retarded the throttle on the good engine. How does someone without the proper training obtain control of an aircraft and kill 42 passengers and crew in this case through sheer incompetence at his job?

[@colinrasmussen9470]

If you are doing 9 actions on an engine failure, you are going to die. There are two things to do. Kill and feather the bad engine. Fuel flow tells you which one has failed. On takeoff, throttles and props are already full forward. After that, gear up, pitch for whatever climb you can achieve. Raise the dead might not be the best thing, since the good engine will help you turn, you just have to be careful about bank angle. Sad that a "Master Pilot" is so wedded to dogma.

[@RedHawk785]

@@colinrasmussen9470 You are right of course. Five seconds of surprised indecision/inaction/incorrect action or trying to take too many actions from memory could be all it takes. I read somewhere that more P-38 pilots were killed in engine-out takeoff accidents than were lost in combat. The beastie had a tendency to flip over and auger in before the pilot could take any action. Ironically I read this in an article written by an aviation journalist who was later killed in a P-38 during an engine-out takeoff accident. I have flown the touchy P-51D with built-in instability and without incident but my instinct for flying a P-38 would be to gain a whole lot of speed margin flying low over the runway during takeoff before climbing away and raising the gear, rather than blindly trusting the engines.

If you can’t afford to fly your airplane regularly, say four hours a month if you have a twin, you really can’t afford your airplane.

[@WarriorsfanDubnation]

Jim Beck how much would you say is enough time for a single engine, to stay proficient?

[@WarriorsfanDubnation]

Jim Beck I’m a new ppl holder, I’ve been averaging 5-7 hours a month.

[@747-pilot]

@@WarriorsfanDubnation I would say, to maintain a basic level of proficiency you would need to fly 25 hours a year, *_at the very least._* That would be something like, say 6-ish hours every 3 months or so. Of course, with this little time, the tricky thing would be to make sure your time includes everything from cross country flying, practicing maneuvers to pattern work!! Also this assumes VFR only. If you have an instrument rating, I would add another 10 to 12 hours a year to stay "instrument proficient" as well! On the other hand, if you have a good home flight simulator (like X plane running on a good computer setup), you can dramatically reduce the additional time for instrument practice, by doing most of it on the simulator and just a couple of hours on the real aircraft itself (as instrument flying is mostly _procedural,_ rather than the "actual feel for the aircraft".)

[@ShuRugal]

@@WarriorsfanDubnation that's my target range to maintain proficiency in my Mooney, keep it from rusting, and be ahead of the hourly cost for renting. if you want to get some good practice on top of that without going out and burning gas, look into a good PC flight sim, and be prepared to spend ~$1,000 on peripherals (a GOOD yoke or joystick, throttle, rudders). If you get a VR headset to go along with it, you can get some very valuable practice. Doing transition training to the Mooney, my instructor advised me to practice pattern work with a P-51 in the simulator, because the wing stalls the same way, and because the hilarious torque that thing generates requires that you fly it actively from engine start to engine stop (I was having a problem with "fixing" while in the landing flare - for the last 3-5 seconds before touchdown, i would just hold my inputs and let the plane find the runway, which resulted in some ugly "arrivals"). After spending 3 hours one night wrestling that torquey son of a bitch around the pattern a few dozen times, my landings the next day in the Mooney were visibly improved.

[@paulvantries7013]

I have been in the cockpit for all my life. You sir are not wrong. Well said !!

[@jackshannon7977]

My experience and that of everyone I flew with was that we could not manage an engine failure in takeoff. We were taught and became a believer in repeated simulator trials to not retract the gear until reaching an altitude where we could control an engine out. If an engine fails below that altitude you just pull the other engine back and land anywhere that is available. That is not popular, and not what you would like to believe. But the simulator will make you a believer!

[@Doodles1947]

"But the simulator will make you a believer!" Well, that would be tragic. As would any loss of an engine anywhere for you given your very wrong understanding of what happens when one calves. First off, it is not altitude that determines when you retract the gear, other than 0 altitude, in which case you might be criticized for raising the gear. Hopefully that goes without saying. Let's analyze this bit by bit. On the takeoff run, you do not leave the runway before you have VMC plus some safety margin that the manufacturer imposes, or which you may add to. The manufacturer must state VMC by law, and it essentially says that is the minimum speed at which the airflow over the control surfaces is sufficient to counteract the yaw/roll that asymmetric power will produce. If you don't have that speed, you are still on the ground with hard surface under both wheels. Cut the good one, and depending on the twin's single engine taxi capability, taxi off the runway and to the ramp. Or get a tow. If you are above VMC, then you are, or very soon will be, in the air. There may be a brief happy coincidence time when even though you are in the air, it is possible to chop power and land on runway remaining. If that is not the case, and it rarely is, you must fly the airplane to save it. It doesn't matter if it is ten feet or 2000 feet, you MUST retract the gear. (Don't spend a lot of time on this if it is an Islander or a Partenavia). Depending on the manufacturer's procedure, you may feather first, or gear up first. Which this is likely depends on the certification flight testing, and which sequence produces the earliest improvement in drag and an ability to climb while maintaining control. i.e. not letting airspeed decay below VMC. Simulators are good for practicing procedures. But they do not test the single most important factor in dealing with an engine out emergency. That is the introduction of the real possibility of imminent death for the pilot and passengers if the pilot cannot perform in the face of that threat. In twin engine aircraft, and in the takeoff mode, a great many can't. Lose the idea that altitude has something to do with when to retract, with the exception of sufficient runway ahead to land, which has an indirect relationship to altitude.

[@TheRotorhound]

I trained in a Beech Duchess and my instructor shut down one engine and I had no problem with dead foot dead engine and complete control. Unfortunately we couldn't restart the dead engine. Had no problems bringing it into our 7000 foot runway and an easy landing. Learned then that you can't taxi with one engine. Scared the hell out of the cfi as I was his first student.

[@johnsouthworthnz]

I have taxied on one engine in a Navajo, it was difficult but doable

[@supersonique001]

Excellent video! And remember Twins=double trouble, never let your guard down!

[@erictaylor5462]

If your twin won't climb or maintain altitude on one engine a twin is a lot less safe than a single engine airplane because an engine failure is now twice as likely, it is still going to force a landing, but in a twin that forced landing is going to take place at a higher speed and asymmetric thrust making a stall/spin more likely. Losing control of a twin engine airplane with a dead engine is a lot more likely than in a single engine plane plane with a dead engine because how the plane responds to control inputs change with a loss of power in the different aircraft types.

[@dougspencer4218]

Ahhhh, OK, so now I can go and watch the videos of Bob Hoover showing us what an accomplished pilot can really do with one engine shut down. He was truly the epitome of perfection as he performed 8 point rolls and 360 degree loops without any problems. Of course, he was also known for doing a lot of his routine with BOTH engines shut down. Mr. Hoover.... you were the best!!

[@computer5272]

You can do whatever you want, as long as you're above Vmc, physics doesn't care who you are. Also in the demonstrations I've seen of him, he's always in a larger transport category aircraft with no load, so if you take into account the situation he's given, it's not that much more impressive than any other aerobatics demonstration. I'm not saying that it doesn't take skill, but it's not as magical and fantastic as people like to exaggerate.

At video time marker 05:15, fatigue. Yes! It is a huge factor. I would suggest that any and every flight school which is teaching student pilots for future commercial careers add a few "Real Life Scenario" hours to the curriculum in order for the students to learn just how to operate while they are fatigued: Learn to recognize when "over the line" fatigued is too great to fly, how to minimize the effects of fatigue, most probable mistakes which are made while fatigued, how the mind and body react to fatigue... If you are going to fly air machines for your paychecks, you will encounter many days and nights of operating while absolutely exhausted. It's a certainty; it cannot be avoided. Learn to recognize it and its dangers. Learn to handle it in the manner which minimizes the dangers as much as possible. And by the way, as a professional pilot working for most any Part 135 operator, you can pretty much toss the "I'MSAFE" checklist out the vent window.

Careful when saying it's not an airliner! My first multi engine entry in my logbook is an Airbus A330

[@rv7ator]

Essentially all general aviation twins have poor single engine climb capability because their one engine inoperative power loading is poor. Many pilots think the performance penalty is so significant due to the additional drag created during flight with one engine inoperative. This is incorrect. Drag matters, but it isn’t the primary reason for the terrible performance. To demonstrate this, assume that your twin has two, 200 hp engines. During flight testing, at L/D max (maximum lift, least overall drag airspeed), it is determined that the airplane needs 150 hp to maintain level flight. During two engine climb, the “excess” horsepower available to climb is 250 hp (400-150), and climb performance is very good. However, during single engine climb, the excess horsepower is just 50 (200-150). This is 80% less than what is available in a two engine climb, hence an 80% performance reduction, which may be further reduced by additional drag due to improper flying technique. Very few multi engine airplanes have good OEI climb capability due to their high OEI power loading. This number for twins used in flight training is usually 21-24 lb/hp, which is terrible. The Diamond DA62 is the worst offender, coming in at 28 lb/hp! Airplanes like the Beechcraft Baron and Cessna 310 are slightly better at about 19 lb/hp, but this is still quite poor, and it won’t do you much good if there’s significant terrain in your way after takeoff. A King Air C90 has a respectable 17.5 lb/hp. The Piper Cheyenne turboprop is the only airplane listed here that I consider to have adequate OEI power loading. It comes in at 14.5 lb/hp.

[@K0nst4nt1n96]

Most GA airplanes only just climb (or just stay level) at blue line, if you are not absolutely nailing that it wont even do that and you absolutely do want that.!!

[@dandianedylan]

Completely agree with your statement, Mark. Any extra airspeed leads to increased parasite drag. Increased drag = less performance.

[@3204clivesinclair]

Mark Lee Agree - a reason exists why the blue line is where it is.

[@XPLAlN]

Yes I totally agree with the above 3 posters. As the blue line is based on max weight and sea level performance, at any weight below max and/or altitude above standard sea level, the blue line is already a few knots faster than optimum. Arbitrarily adding 5 knots to blue line as shown in the video will further degrade performance and is the WRONG advice. The right advice is to "nail" the blue line speed as Mark Lee said. In the video, they make the point that the book numbers are based on brand new aircraft and you might not get the same performance, which we all know is true. However, if the engine is producing less than rated power, the actual Vmca will also be lower increasing your margin between blue line and losing directional control. So with a down on power engine there is even less justification to squander remaining performance by flying above blue line speed than there is if the engine is performing to spec!!

I had to shut down the right side of my B58 Baron at 10,000' over the Chesapeake Bay. We were IFR planned to Savannah when the plane yawed to the right; I couldn't straighten it out without stepping on the left rudder pedal. Throttle inputs wouldn't do it, so I shut down that engine and feathered the propeller. Came to find out the propeller had gone to feather before I shut down due to a lack of oil pressure to the prop governor. A gear had blown in the case. My wife and two daughters were with me. ATC asked me where I wanted to land, and I said take me to the airport that is nearest my current heading, which was Patrick Henry in Williamsburg. One of the choices was Norfolk Naval Air Station :). Anyway, it was uneventful, but my wife was pretty nervous, especially when she saw fire trucks at the side of the runway as we made our approach and landing. We had to be towed to the ramp as I didn't have thrust on the right side and couldn't steer the plane.

[@pauleyplay]

Prop went into feather due to lack of oil pressure ? So prop feathers at every shut down ? Nothing about your story rings of truth !

[@nameless-sn3tj]

@@pauleyplay The false expert. Allow me to educate. First, yes twins do feather with a lack of oil pressure. They do this because in the event of an engine failure you want to secure the engine not restart because you have a spare engine. Singles do not. This failure is exactly why. You could fly the single to a landing site and the multi engine can do the same. Second, no the props do not feather on shutdown because there is a mechanical lock, called the anti-feathering pins, that prevents feathering below a certain RPM. This is why it is important to feather a failed engine quickly before the RPM drops otherwise it may be locked. In short, this story is exactly what is designed to happen. Perhaps next time you will spend a few minutes on a reputable search engine before claiming something so easy to check is a lie?

[@pauleyplay]

@@nameless-sn3tj Sorry about my mistake. I have been a pilot & A&P all my adult life. Sorry but you are wrong. Constant speed props always default to flat pitch. I could be in a world of trouble in a aborted landing with a prop attempting to feather. Most engines don't respond to the prop control below about 1500 Rpm. Blades assume flat pitch due to spring loading. The governor pushes against the spring moving the blades. No locks, How would that work. Centrifugal force ? We do unlock king air props out of feather, that's another story. Many good post showing how this works

Or perhaps you would care to google "anti-feather latch pins"? Also, your engine failure on takeoff won't attempt to feather because a) windmilling props will maintain oil pressure for quite some time, and b) the engine won't feather because of the anti-feather latch pins. -CFI, CFII, MEI, and occasional wrench turner.

@ Paul Van Tines I can tell you’ve never worked on a Hartzell Compact Feathering propeller before. Springs, nitrogen pressure, and counterweights as well as the aerodynamic twisting on the blades will turn it to *FEATHER!* The _only_ things that keep the blades in fine pitch are oil pressure and the pitch locks when the engine is shut down (this is why you need to feather most props before RPM decays below 900 RPM since the pitch locks are engaged below that) and why the prop will feather it you accidentally left the prop lever in the cruise setting. Yes, a single engine constant speed prop goes to fine with no oil pressure. Why it does that, I have no clue. Because on the fine pitch stops you can’t pull any power without greatly over-speeding the engine... and it absolutely kills your glide ratio.

[@neilrobinson3085]

The V1 concept is only valid in transport category aircraft and does not apply to piston twins. Piston twins are never guaranteed to have engine-out climb capability. The diagram at 6:00 should have specified Vr instead of V1. This diagram also implies that accelerate/stop distance and accelerate/go distance are the same; this is rarely the case. Accelerate/go is often much longer.

[@jimmbbo]

VYSE varies with weight.. arbitrarily adding "a few knots" may sacrifice the ability to climb or maintain altitude in most Part 23 multiengine airplanes.

[@davidwhite8633]

jimmbbo You will probably also be below MGTOW as well with fuel burn, unless you took off over-gross; and remember, VY and VYSE decrease with altitude, so, all-in-all, the true blue-line in an average situation at altitude will probably be(depending on your actual weight) a few knots lower than on the A/S indicator. More than enough to turn miserable SE climb rates to zero or even negative , as you said.

It’s a lot easier to go from fast to slow than slow to fast if you’re wrong.

I remember back in 1967 after I had got my PPL and then went and got my COMM License, my first twin was a 500B and what a laugh trying to taxi the down the taxiway in a striaght line. I was deliberatly conned as no one told me about differential braking. I got my revenge years later when I was teaching someone to fly the Shrike model. He saw the funny side but realised that this was more than jus another twin, it was truly a magnificent airfraft. I live in Australia and about this time last year, I ferried a 690B from Ohio to Darwin and then downt to Perth. Myslef, I have had the good fortune to have been flying one for the past 40 years. Its undergone many restorations, but has been put to good use by government departments and tourists. The295 HP Lycomings were replaced with two 345 HP Lycomings and its a beast on climb out .2800 ft per minute to 10,000ft and will sit at 15,000 ft all day ( but need oxygen ) so rarely fly over 10,000 ft. A majestic aircraft if ever there was one.,

[@gobysky]

If you don’t learn proper rudder coordination and use during an engine failure, not to mention airspeed maintenance, you’re dead. It’s basic and simple and requires periodic practice. This applies to any airplane, become really proficient in basic stick & rudder flying first. Let’s not complicate the process.

Never turn toward the dead engine. Unless you have the skill of Bob Hoover...

I agree with most everything in this video. EXCEPT: adding a few knots to the published blue line. I have flown right seat in a PA31P-425. The very type proficient instructors have taught to NOT overfly blue line. Yes. flying yes is worse, but the damn airplane wont climb much at all 5-10 knots above blue line on single engine... a generic suggestion to fly faster than blue line is not always a good idea.

[@Bartonovich52]

That’s nice. I’ve got thousands of hours in twins right and left seat piston and turbine and I agree with the video.

I also agree it's not a good idea to add a few knots to blue line. You want to hit blue line as close as possible to maximize your single engine climb rate.

Something to do with lawyers ability to sue the makers because with one engine there is no guarantee of being able to maintain height or climb.

[@Bartonovich52]

It didn’t last because 1) it was useless to train pilots to fly conventional twins and 2) it wasn’t any safer due to the complex fuel system, the tendency of the rear engine to overheat and fail before takeoff without the pilot knowing, and the difficulty identifying the failed engine due to lack of yaw (or in some cases.. with a failed rear engine and a low speed, high power setting, and a lot of right rudder... the yaw going the wrong way).

He flew a lot of twins and practice engine outs all the time. But they all perform differently and our expectations should be as such. We have to seriously respect the twin engine out scenario.

[@andrewbatistoni5779]

I actually did this (landed with shut down engine and taxied off ) Its possible to turn off with a little momentum but once you slow to taxi speed its impossible in some planes (seminole, cough). Not that it matters. No amount of taxi inconvenience is worth crashing.

[@Alex-us2vw]

Add a few knots to blue line? Adding a few knots to redline seems more appropriate. Adding knots to blue line will only decrease single engine climb performance. Why would you want to decrease climb performance when already struggling to climb after an engine failure? You might only have 150-200fpm climb rate with everything done perfect at max weight, pitching for the incorrect VYSE airspeed to make this even worse seems silly.

Agree, seemed like a mistake to say that in the video.

@ Rafey1, you are terribly confused. They are all flat engines because their cylinders lie flat. They are all opposed engines because their cylinders oppose each other. Only the four cylinder flat opposed engines are Boxers which are named because of “boxing” motion the same side pistons make. Any four cylinder Porsche, Subaru, Lycoming, or Continental engine is technically a “boxer”.. but the term is rarely used in aviation. And to the OP yes no I6 or flat 6 engines use cranks with shared throws. However, V6s do and some are used on aircraft (the Centurion 3.0 was just certified).
