In 1988 TACA flight 110 from Belize to Louisiana was both engine lost. The aircraft make a safe landing in a grass levee. (http://en.wikipedia.org/wiki/TACA_Flight_110)

 

The Boeing engineers and test pilots perform an engine change, and the aircraft take off with only one engine.

 

My questions are:

 

1. Is it possible that a NG take off with only one engine (starting in idle power with only one engine)?

2. What adjust i need to make in control surfaces (rudder, aileron and pitch) for a safe departure?

3. If is possible, can you includes a maneuver example, with left or right engine running?

 

Thanks!

In that incident they did not take the aircraft off on only one engine. If I recall, the right engine had to be replaced as it was badly damaged and, while the left one was in need of an overhaul, it'd survive the flight. That strip the pilots landed on was barely long enough to land the aircraft, they weren't going to push their luck and try taking off from essentially a field on just one engine.

 

If it is possible, which I doubt, you'd need to use some serious rudder trim as well as being very cautious of the aircraft rolling on lift-off.

Thanks for your reply!

Thanks for your reply!

 

The main issue would be the fact the nose-wheel steering becomes very ineffective beyond 30-40 knots (and you don't want to be using it beyond these speeds anyway) and the rudder won't be very responsive until 80 knots. So you've got that window with limited control.

Possible yes, practical no. To the best of my knowledge, there is no civilian aircraft (revenue flight and no revenue for that matter) that can legally take off with one engine inop. In a practical sense, you can do a single engine takeoff on a DHC8 I know for sure. (Dont ask me how I know this ).

 

Thanks

Possible? Maybe on a very long runway.

 

No operator would allow that however. Can you imagine the legal consequences if the ACFT crashes....

747 can take off with 3 engines. I don't know if that's ferry-only.

If you try it in the sim you'll never get above 20 knots without losing directional control. I've tried it a couple of times and unless you put in full thrust the aircraft acceleration is too slow for even a 12,000 foot runway. If you do use full thrust you lose directional control and spin out.

 

Not happening in the sim, at least.

You never takeoff with one engine inoperative. In the simulator, it is even more difficult because of the sh**y ground physics (thank you microsoft) -.-

Directional control would be an issue the second the engine sppols up to takeoff thrust.

Legally you MUST take off with one engine if:

1-You're losing the engine during take off phase

2- you passed V1

 

Before V1 abort take off.

This is valid for twin engine aircrafts, I don't know for others.

Starting a takeoff with an already failed or OFF engine is not allowed as already stated before.

If it is possible technically speaking or not depends on a lot of factors, including the aircraft type, runway lenght and conditions. But however, this must be tested, I don't think anyone did it with a 737.

Yes, but, if you passed v1, you have enough airspeed to maintain directional control using the rudder. He was talking about starting takeoff with only 1 engine.

The full takeoff from 0kts could only be theorical, or someone must show us tests, or experiments about it on a 737.

However, the aircraft control in this situation is related to aircraft weight, runway lenght and so on, and power modulation.

It is obvious that power must not be applied fully if you have no rudder.

So, we need a light airplane (no passengers, no full of fuel), a great runway (something like the deserts that are used for some speed record tests) and a delicate hand that applies power gradually in a manner that the power is sufficient to only add a bit of speed time after time, when speed will be sufficient for rudder, it could be possible to add a bit more power.

With a light aircraft it could be done.

However, this is all theorical.

Monday morning counseling session with management :

 

- So, what happened? A dual engine failure on take-off ?

 

Oh, no, not at all boss. You see, it's funny but, at the time, we thought it would be a good idea to take off single engine. But then the bloody engine failed and things began going downhill (just like the plane by the way)...."

Hi,

Definitvely NOT POSSIBLE to take off with just one engine by starting from 0 speed!!!

You shuold know that you can't have directional control (rudder) if your speed is under Vmcg (Velocity minimum control on ground)!! Here it's why V1 MUST BE ALWAYS greater than Vmcg!

B744 is different having 4 engine so you always have TWO SIMMETRICAL ENGINE in any case, in fact there the technique is:

1) Aircraft at minimum wight no pax ecc. crew qualified for that takeoff

2) At takeoff (NO autothrottle naturally) the two simmetrical engine throttle are pushed forward at TO power BUT the third engine is mantained at idle till overpassed the Vmcg here it's how it can possible taking off there!

Best Regards
