Flight Theory & Principles Flashcards

What is the load factor in a level, coordinated turn at a 60-degree bank angle?

Answer: 2 G

Load factor equals 1/cos(bank), and 1/cos 60° equals 2 G.

By approximately what percentage does stall speed increase in a level 60-degree bank turn?

Answer: About 41 percent

Stall speed rises with the square root of load factor, and the square root of 2 is about 1.41.

At a constant airspeed, increasing the angle of bank in a level turn will:

Answer: Increase the rate of turn and decrease the radius

A steeper bank increases the horizontal lift component, turning faster in a tighter circle.

If bank angle is held constant and airspeed is increased, the turn will have:

Answer: A larger radius and a lower rate

At a constant bank, higher airspeed increases turn radius and reduces rate of turn.

What causes adverse yaw when ailerons are deflected to roll into a turn?

Answer: Increased induced drag on the rising wing with the down aileron

The down aileron produces more lift and therefore more induced drag, yawing the nose away from the turn.

How does design maneuvering speed (VA) change as aircraft weight decreases?

Answer: It decreases

A lighter airplane reaches its limit load factor at a lower airspeed, so VA decreases with weight.

Approximately what load factor is imposed in a level, coordinated 45-degree banked turn?

Answer: 1.41 G

1/cos 45° is approximately 1.41 G.
