What effect does using flaps have on the lift coefficient (CL) and drag coefficient (CD)?
What effect does using flaps have on the lift coefficient (CL) and drag coefficient (CD)?
- Is indicated for turns
- Increases CL and CD (correct)
- Generates higher downforces
- Increases CL by reducing CD
In a constant altitude coordinated banked turn, what is the relationship between the bank angle and the speed of the aircraft?
In a constant altitude coordinated banked turn, what is the relationship between the bank angle and the speed of the aircraft?
- Bank angle has no effect on speed
- Increased bank angle leads to a decrease in speed
- Bank angle and speed are inversely related (correct)
- Bank angle and speed are directly proportional
