44
Q

Define angle of attack?

A

Angle between the Chord Line and Relative Airflow.

45
Q

A

The Stalling Angle.

46
Q

If the IAS is kept constant, will an increase in angle of attack increase or decrease the lift?

47
Q

If the angle of attack is kept constant, will an increase in Airspeed increase or decrease the lift?

A
