There are a lot of unnecessary fears in flying, or at least fears that are overblown. How many aircraft owners resist adding a multi-engine rating, or shy away from buying a twin, based on the fear of loss of control when an engine fails on takeoff? It is certainly a valid concern, and dealing with sudden asymmetric thrust at this critical stage of flight is addressed in every multi-engine training program. Multi-engine pilots are wise to revisit the issue equally comprehensively in their regular recurrent training. One reason why it stands out from other worries about flying proficiency is that, unlike most decisions that pan out over extended time, an engine failure on takeoff requires quick, decisive action. But here's some simple advice that, for me at least, puts that fear in perspective. It comes from my friend Wayne Lincourt, Irving, Texas, former associate publisher of Flying.

Mark,
I continue to enjoy reading your newsletter. There's always good info, including the flying tips.

One of the most critical phases of flight, of course, is on takeoff where an engine failure forces the pilot to make a split-second decision on whether to continue the takeoff or keep it on the ground. The tip I got from FlightSafety International made that decision a no brainer.

The technique they taught was to keep your hand on the throttles until you raised the gear and then to move your hand from the gear switch to the prop controls. If you lost an engine while your hand was on the throttles, you simply pulled both throttles back and got on the brakes. If your hand was on the prop controls when an engine quit, you feathered the offending engine and continued your takeoff. Decision making doesn't get much simpler than that.

Hope this is a tip you can use in your newsletter. Keep up the good work.

—Wayne

Thanks, Wayne.

Far be it from me to question Flight Safety, but I don't know about this one. I can be well past V1 by the time I go to the landing gear. Also, I'd be cautious about recommending hasty feathering. We're taught to "identify, verify, cause check, feather...". I agree that there's no time to do much of a cause check after an engine failure on take off, but feathering the wrong engine will make matters much worse. Perhaps better to focus on flying the plane first. The real issue is power vs airspeed when below Vmc. Management of this aspect of the emergency will result in a successful outcome.

What if you hand is on the gear up control?

They taught that to me 20 years ago. Traditional CFI's do not like it becasue you can only practice it in the Sim....but it is a great system. Part of it was "go right , pull right.......go left,pull left" which works for VFR.....need a different cue system for IFR

This hint works for turboprops and high powered twins. But I think there needs to be more thought about the decision process that should take place before pushing the throttles forward.

If you fly a light twin, especially with a heavy payload and at a high density altitude, there are times when if you lose an engine after take-off, even with the gear up, the climb might be so anemic and the surrounding geography so risky that the best decision might be to pull both throttles back and simply look for a place to land.

I recently lost a friend that was an ATP, along with two others, in a cabin class twin in what seems to have been a Vmc loss of control accident. If he'd simply pulled the throttles to idle and chose one of the (few) nearby landing areas he would probably still be alive.

The more I think about this, the more unsafe this advice sounds, unless your comments were somewhat incomplete. With a suspected engine failure in a multi-engine airplane, I learned "Identify (dead foot, dead engine), Verify (pull the throttle back on the 'dead' engine), Feather". By suggesting that a pilot move his/her hand over to the prop controls after gear up and feather the dead engine, should one fail, without Identifying or Verifying the correct engine, this could easily lead to the pilot feathering the wrong engine. A better approach might simply be "Gear down, stay or get back on the ground. Gear up, head up into the sky, Identify, Verify, Feather".

I am not sure putting the hands on the prop levers are such a good idea until you know what engine to feather. It only takes a moment to pull the suspected bad engine throttle back and then the engine can be verified. Sometimes the engine runs ok with reduced power and the chances of shutting down the wrong engine are reduced.

Great tip. Remember dead foot dead engine. Don't pull back the wrong engine.

I would generally agree with all of the other skeptical commenters. This sentence in particular is questionable: "If you lost an engine while your hand was on the throttles, you simply pulled both throttles back and got on the brakes." I and most pilots I've seen keep their hand on the throttles throughout the takeoff roll and a few seconds after breaking ground to ensure the throttles don't slip toward less power. So in quite a number of cases, the airplane could be quite well airborne with the hand still on the throttles - pulling them and braking at that point wouldn't work. Generally I think this tip is way too simplified.

you guys are absolutely right. and we all say under our breath - "when you figure out the correct procedure, it still, ALWAYS, becomes a matter of training. training training TRAINING.
.
'course i will admit - if i had the money - i'd forget all about this and buy a TBM850.

I give pre-employment flights in our company's Baron. I have seen more than one pilot candidate feather the good engine during a simulated engine failure at altitude. Being correct is always more important than being fast in a piston twin. I think having a hand on the prop controls at low altitude is a really bad idea.

The writer is talking about the period immediately after rotating into the climb. At that point, power output is high and airspeed is slow, so when an engine quits, I can assure you it will be readily apparent which prop to feather....yaw left, feather left; yaw right feather right. I have used this technique for many years and have taught it in flight to multi-engine students in Piper Apache's, Seneca's and Aztec's, Cessna 310's, and beeccraft Baron's. It works.

Every, and I emphasize the word "every", situation is different and only the guy in the seat at the time can make the decision.

That said, there is no hard and fast rule that says because you have the ability to go that you must go. If in doubt, whether because of performance or terrain, perhaps it would be better to run through the fence at 40Kts decelerating than to rip through the treetops at 140Kts attempting to demonstrate single-engine performance that isn't there.

con sider increasing the speed that you rotate at in a twin evaluate the runway length then consider your stoping distance if you rotate closer to vmc then loose an eng the one engine will cary you past vmc and over the fence and give you the time need to respond if the run way is to short to stop shy of the fence comsider your folly this is your choice prior to rotation. in a twin you have the ability to stack the odds in your favor with a single not so ! look at the stats most fatality that occ with in the pattern are due to trainning. watch who you train with and where you train< know your speeds and your aircraft>know your single engine performance leave nothing that you can control to chance Dan

My understanding of the 'hands off the throttles/power levers at V1' procedure is to prevent inappropriate dangerous attempts to abort after an engine loss when you have the ability to depart, gain safe altitude, and then determine how to best deal with the problem. Great if you're in a high powered turbine. As others have observed, a low powered piston twin at gross at high density altitude might require an appropriately different plan (e.g. as mentioned earlier, accept that you can not climb out OEI and find the best suitable off field landing location; or better yet, unload weight or wait for cooler air).

The key is the PIC must have a clear plan in mind, best articulated verbally, before every take off as to what will be done if any abnormal condition occurs during any segment of the take off roll. Clearly the 'plan' will vary wildly depending on the equipment, loading, environmental conditions, crew resources and proficiency, etc.

Ok, good, both engines healthy, airspeed alive, Vr, rotate, V1 confirmed, hands off the throttles/power levers. Where to place your mighty right hand now (after deftly flipping up the gear - I know controversial itself: if departing on a 12,000 ft runway why raise the gear immediately after take off, at lower speeds they don't contribute that much to drag and are handy if you need to abort)?

I guess the prop levers are a good choice. The problem, as observed earlier, is that in the anxious moments during an engine loss at lift off it is too easy to feather the wrong engine in haste. I'd love to hear what the Navy procedure is for their turboprops for carrier take offs. Ain't gone stop on the deck.

It's good to see that the first response is the correct one. We should always identify the offending engine as a FIRST course of action. Everything else follows. Many a pilot has feathered the wrong engine.

Much of the comments here seem to assume single pilot ops. In my opinion, two heads seem to add the addutional comfort of knowing that there is not the necessity to rush to feather. I have instilled in my past ME students that once the affected engine has been identified and verified, to move the dead prop lever back slowly. If it's the wrong prop lever, you will experience the change in sound and thrust instantly. Then it becomes one of those OMG thoughts and signals you to put things back where they were. This may be over simplifying the problem, but it seems to work well. As mentioned above, especially in single pilot ops, have a plan of action before taking the runway and don't allow yourself to be rushed. In most light twins, failure below Vmca or at lift off should be a planned abort even if it means going ino the weeds. After liftoff with gear in retraction, most of us will go flying, usually.

In two pilot ops, we usually brief the take off plan should something bad occur. Do the same for single pilot ops and you have planted the plan in your mind be for the takeoff.

For what it's worth.
