Re: Airplanes



This sounds good, except I seem to remember the Super 80 with rear engines.



But it's the first time I've flown on that type.
More-likely hypotheses include:
-- The engine on one side might be producing slightly more thrust
than the engine on the other side, resulting in the airplane flying
in a slight slip. For details see
http://www.monmouth.com/~jsd/how/htm/multi.html#sec-1out-coordination
-- Since both engines rotate the same way, they dump a nonzero
amount of angular momentum into the air. (This phenomenon is quite
conspicuous on propeller aircraft; on jets it is less conspicuous
but still present to some degree.) To compensate, you need to hold
a steady aileron deflection, especially during high-power low-airspeed
flight.
