Aviation Aerodynamics & Aircraft Performance 3

Question 1

What is load factor (G-force) in aviation?

Accepted Answer

The ratio of lift to aircraft weight, expressed in Gs

Answer

Load factor is the ratio of lift to the aircraft's weight; a load factor of 2G means the wings are producing lift equal to twice the aircraft's weight.

Question 2

During a 60-degree banked level turn, approximately what load factor does the aircraft experience?

Accepted Answer

2G

Answer

A 60-degree banked level turn results in a load factor of 2G because the wings must produce twice the normal lift to maintain altitude.

Question 3

What is the purpose of Maneuvering Speed (Va)?

Accepted Answer

The maximum speed at which full or abrupt control inputs can be made without exceeding structural limits

Answer

Va is the maximum speed at which full deflection of any single flight control will not exceed the aircraft's structural design load limits.

Question 4

How does a tailwind affect landing distance?

Accepted Answer

It increases landing distance because the aircraft has a higher groundspeed at touchdown

Answer

A tailwind adds to the aircraft's groundspeed at touchdown, requiring more runway to decelerate to a stop even though airspeed may be normal.

Question 5

What effect does high humidity have on aircraft engine performance?

Accepted Answer

It decreases engine power because water vapor displaces oxygen in the air-fuel mixture

Answer

Water vapor displaces oxygen molecules in the intake air, reducing the oxygen available for combustion and therefore decreasing engine power output.
