Tri vs Twin-jet

[Jedi_Cheese]

A light multi would be a nightmare to fly for multiple hours across the atlantic with an engine out. Many of them don't have rudder boost and thus you would need to manually keep directional control for the rest of the flight. You would also level out at several thousand feet which would kill your ground speed and fuel burn.

On the other hand, you are better off than in a single engine b/c at least if you do a precautionary water landing, you can get closer to a rescue point, and make shure that someone knew where you were and what you are up to.

Even a light airliner should have no problems with keeping a safe distance above the ground and I believe that most have rudder boost. It isn't like your day is about to become hell like in a light twin but it isn't going to be something to celebrate.

From what I heard, the only time a 2 engine jet airliner had twin engine failures over water was an A320 when a fuel pump broke that ran fuel to both engines. It made a landing in the Azores and they changed the design after that.

Has there ever been a 3 engine failure on a 4 turbine engine aircraft? That has to be some serious FOD (hail, birds, or water) in order to do that or some sort of wierd mechanical failure.

The Boeing 727 simply does not have the power to execute a missed approach on one engine. It does have the power to do so on two engines, but at much reduced performance. You are committed at a certain point on an approach, depending on which engines you have operating.

It was an Airbus 330 not 320, and that phenomenal display of airmanship might have been prevented by better “troubleshooting”.

A KLM 747 lost all 4 engines flying into volcanic ash up in Alaska some time back, they were able to get partial power back in at least two engines and landed safely though badly damaged from the ash.
