What if one of the 2 engines fail? Can it fly sideways?
They can fly on only one engine.
When one of the engine fails I assume the pilots have to stand on 1 foot on the rudder pedal closest to the one running engine while they try to forget the sh*t running down their pants.
I would also assume that they would throttle down a bit from the usual power but thatbisnjust a guess.
“What if one of the 2 engines fail? Can it fly sideways?”
Twin engine airliners have been dominant in the market for a very long time. They fly the longest routes.
There are many examples of twin engine planes operating on one engine.
To be certified to carry passengers they must be able to take off, fly, and land at max weight with one engine inoperative.
They must also maintain a very high record of engine reliability to remain certified for long range twin engine operations.
All large twin jets are ETOPS “Extended-range Twin-engine Operational Performance Standards”.
For example, an aircraft that has an ETOPS 120 is rated to fly 120 minutes on a single engine to reach an alternate airfield.
The Boeing 777 is rated at 320, and the Airbus A350 is rated at 370. The average though is about 180 minutes.
As far as flying sideways, the flight control computer will compensate for the engine loss by adjusting the trim and adding rudder input.
