Discussion
Arrange these events during an engine failure just after take-off:
1. One engine fails and asymmetric thrust appears
2. A yawing moment develops towards the dead engine
3. The pilot applies rudder to balance it
4. A small bank towards the live engine reduces the rudder required
5. The aeroplane climbs away under control
Select the correct sequence.
Answer: D
Correct answer: 1, 2, 3, 4, 5
The order follows the physics and then the pilot's response. The engine fails, leaving thrust on one side only; the resulting moment yaws the nose towards the dead engine.
The pilot's first action is rudder, which balances that moment directly. A small bank of a few degrees towards the live engine follows, letting a component of weight assist the rudder so that less deflection - and less rudder drag - is needed for the same balance; this is why the certified minimum control speed assumes a bank of up to five degrees. With yaw balanced and drag minimised, the aeroplane climbs away.
