CPL Aircraft General Knowledge 5

Question 1

As bank angle increases in a coordinated level turn, load factor:

Accepted Answer

Increases because total lift must increase to maintain altitude

Answer

Decreases because horizontal lift replaces vertical lift

Answer

Remains constant if airspeed is held steady

Answer

Decreases because induced drag reduces the effective lift vector

Question 2

Maneuvering speed (Va) is defined as the speed at which:

Accepted Answer

The aircraft will stall before exceeding its structural load limits from a single full control input

Answer

Flaps may be safely extended to the takeoff position

Answer

Turbulence penetration is most efficient

Answer

Best angle of climb performance is achieved

Question 3

An aircraft loaded with the center of gravity at the AFT limit will exhibit:

Accepted Answer

Reduced longitudinal stability and potentially unrecoverable stall characteristics

Answer

Increased longitudinal stability and positive stall recovery characteristics

Answer

Greater nose-heaviness requiring continuous aft elevator trim

Answer

Higher stall speed due to increased wing loading

Question 4

What effect does exceeding maximum gross weight have on aircraft stall speed?

Accepted Answer

Stall speed increases because the wing must generate more lift to support greater weight

Answer

Stall speed decreases because more lift is generated at lower angles of attack

Answer

Stall speed remains the same — weight does not affect the aerodynamic stall angle

Answer

Stall speed varies only with bank angle, not with weight

Question 5

Winglets (vertical tip extensions) on aircraft wings primarily serve to:

Accepted Answer

Reduce induced drag by disrupting and weakening wingtip vortices

Answer

Increase low-speed lift by acting as additional lifting surfaces

Answer

Increase wing structural rigidity against flutter at high speeds

Answer

Improve directional stability by acting as small vertical stabilizers

Question 6

Density altitude is correctly defined as:

Accepted Answer

Pressure altitude corrected for non-standard temperature

Answer

The altitude indicated on an altimeter set to local QNH

Answer

True altitude corrected for instrument position error

Answer

The altitude at which standard atmospheric density exists above sea level

Question 7

Which primary flight control governs rotation around the aircraft's longitudinal axis?

Accepted Answer

Aileron

Answer

Elevator

Answer

Rudder

Answer

Stabilator
