1.7: Properties of a Turn

Question 1

What force makes an airplane turn?

A. The horizontal component of lift.
B. The vertical component of lift.
C. Centrifugal force.

Answer 1

The horizontal component of lift.

Question 2

What is adverse yaw?

Answer 2

When applying aileron to bank the airplane, the lowered aileron (on the rising wing) produces a greater lift and a greater drag than the raised aileron (on the lowering wing). This is commonly referred to as adverse yaw.

Question 3

What is the effect of adverse yaw?

Answer 3

This increased aileron drag tend to yaw the airplane toward the rising wing (opposite the direction of the turn) while the banking action is taking effect.
