CORRECT!

4). The three conditions which determine pitch attitude required to maintain level flight are

a). relative wind, pressure altitude, and vertical lift component.
b). flightpath, wind velocity, and angle of attack.
c). airspeed, air density, and aircraft weight.
The answer is:
c). airspeed, air density, and aircraft weight.

Airspeed: as the airpseed increases, the increased flow over the wing creates more lift, requiring a concurrent pitch change to stay at level flight. Air density: as air density changes, a concurrent pitch change will be needed to maintain level flight. Aircraft weight: the heavier the aircraft, the harder the wing has to work to generate the amount of lift required to carry the heavier weight and, thus, angle of attack to maintain level flight goes up as weight increases.
