Aerodynamics

What is the purpose of a servo tab?. Reduce control forces by deflecting in the proper direction to move a primary flight control. N/A. N/A.

When piloting a turbojet transport airplane, what is a possible result when operating at speeds 5 to 10 percent above the critical Mach number?. Decreased control surface effectiveness. N/A. N/A.

If no corrective action is taken by the pilot as angle of bank is increased, how is the vertical component of lift and sink rate affected?. Lift decreases and the sink rate increases. N/A. N/A.

What is the principal advantage of the sweepback design wing over a straightwing design?. The critical Mach number will increase significantly. N/A. N/A.

What is a characteristic of longitudinal instability?. Pitch oscillations becoming progressively greater. N/A. N/A.

For a given angle of bank, the load factor imposed on both the aircraft and pilot in a coordinated constant-altitude turn. remains constant regardless of airspeed changes. N/A. N/A.

What effect does the leading edge slot in the wing have on performance?. Changes the stalling angle of attack to a higher angle. N/A. N/A.

What flight condition should be expected when an aircraft leaves ground effect?. An increase in induced drag requiring a higher angle of attack. N/A. N/A.

What are some characteristics of an airplane loaded with the CG at the aft limit?. Lowest stall speed, highest cruise speed, and least stability. N/A. N/A.

What is the movement of the center of pressure when the wingtips of a sweptwing airplane are shock-stalled first?. Inward and forward. N/A. N/A.

When are inboard ailerons normally used?. low-speed and high-speed flight. N/A. N/A.

Generally, the turning performance of an airplane is defined by. aerodynamic and structural limits at low altitude. N/A. N/A.

How does the stall speed (KCAS) vary as you climb from sea level to 33,000 feet?. It remains relatively unchanged throughout the climb. N/A. N/A.

A bank angle of 15 degrees will increase induced drag by about. 7%. N/A. N/A.

What effect does an increase in airspeed have on a coordinated turn while maintaining a constant angle of bank and altitude?. The rate of turn will decrease resulting in no changes in load factor. N/A. N/A.

What is a purpose of flight spoilers?. Reduce lift without decreasing airspeed. N/A. N/A.

For what purpose may flight spoilers be used?. Reduce the wings' lift upon landing. N/A. N/A.

What affects indicated stall speed?. Weight, load factor and power. N/A. N/A.

An airplane loaded with the Center of Gravity aft of the rear CG limit could. make it more difficult to flare for landing. N/A. N/A.

Which is a purpose of leading-edge flaps?. Increase the camber of the wing. N/A. N/A.
