Trivia Teaser: Best glide, but with a wrinkle

A pilot is in gliding flight at the optimum indicated glide speed and then enters a turn. To maintain a maximum-range glide during the turn, glide speed should

A)            be increased
B)            be decreased
C)            remain the same
D)            be decreased when entering the turn, then increased when bank angle is constant

A. To maintain a maximum-range glide during the turn, glide speed should be increased. Turning flight results in an increase load factor, which increases the effective weight of the airplane.
