Lesson 1.8 Turns

1. At a constant altitude in a coordinated turn, each airspeed has a specific, unvarying rate and radius of turn for each angle of bank.
a. An increase in airspeed in a level, coordinated turn with a constant bank results in an increase in the radius and a decrease in the rate of turn.
b. Steepening the bank and decreasing the airspeed results in an increase in the rate of turn and a decrease in the radius.
2. With a constant bank angle, the load factor will be constant regardless of
a. The rate of turn
b. Airspeed
c. Weight
3. As bank is increased, additional vertical lift converts into horizontal lift, decreasing available vertical lift.
a. Thus, an increased angle of attack (back elevator pressure) is required in order to maintain a constant altitude during the turn.
4. When airspeed is increased during a level turn, the angle of attack must be decreased or the angle of bank increased to maintain level altitude.
5. A standard rate turn is, by definition, 2 min. for 360°, or 3°/second.
a. To maintain a standard rate turn as the airspeed increases, the bank angle of the aircraft will need to increase.
