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

In a level turn, total lift must support aircraft weight plus provide centripetal force, so load factor (lift/weight ratio) rises with bank angle.

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

At or below Va, abrupt full deflection of any single control surface will cause the aircraft to stall aerodynamically before structural load limits are exceeded.

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

An aft CG reduces the stabilizer's restoring moment arm, degrading longitudinal stability and making stall recovery more difficult or impossible.

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 increases with weight because the wing must fly at a higher angle of attack (or higher airspeed) to generate the additional lift needed.

Question 5

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

Accepted Answer

Reduce induced drag by disrupting and weakening wingtip vortices

Answer

Winglets redirect the energy of wingtip vortices, effectively increasing aerodynamic span and reducing induced drag without adding significant wing length.
