Hi,

During a level balanced turn at constant bank the effect of increasing power will be
Choose one answer.
rate of turn will increase and radius of turn will decrease Incorrect
both rate and radius of turn will increase Incorrect
rate of turn will decrease and radius of turn will increase Correct
rate of turn will be the same but radius of turn will decrease Incorrect
Increased power will result in an increase in speed. If bank is kept constant and speed is increased, the radius of turn will increase with the square of the speed. Because the radius of turn increases more rapidly than the speed does, the aircraft actually take longer to complete the turn at the higher speed! Radius of turn increases and rate of turn decreases.

you said it will take longer to complete the turn but yet the answer is a lower rate??? that doesn't make any sense. answer should be B should it?

Many students have problems with the concept of rate of turn. It is true that if it takes longer to do a turn, the rate of turn has decreased. The rate at which something happens decides how long it will take to complete the operation. The speed of your car on the highway determines the rate at which you cover a given distance. A journey takes longer if the rate at which you cover distance decreases.

The rate of turn is the number of degrees by which your heading changes with time. A turn of 3° per second is a lower rate of turn that a turn of 6° per second. If you turn at the lower rate [3° per second], it will take longer [more seconds] to complete the turn than it would at the higher rate of 6° per second.
