Plane in the wind

[vette982]

This problem applies to automobiles too:

An airplane flies in a straight line from airport A to airport B and back. It has constant engine speed and no wind.
Will its total flight time increase, decrease or stay the same if throughout both flights there is a constant wind blowing from A to B?

Since a plane always takes off and lands into the wind, the overall distance will be longer if there is wind, hence increasing the airborne time.

However, the way the question is posed, it will always increase whether it is a plane or a car etc etc.

If it was an Air Canada flight, total flying time will increase to meet the airline's on-time, aka 1 hr delay, average
