Which is true regarding the force of lift in steady, unaccelerated flight?
a. At lower airspeeds the angle of attack must be less to generate sufficient lift to maintain altitude.
b. There is a corresponding indicated airspeed required for every angle of attack to generate sufficient lift to maintain altitude.
c. An airfoil will always stall at the same indicated airspeed; therefore, an increase in weight will require an increase in speed to generate sufficient lift to maintain altitude.
