ADX ADX Aircraft Performance and Weight Balance

Question 1

What is the maximum allowable takeoff weight (MTOW) of an aircraft?

Accepted Answer

The maximum certified weight at which an aircraft may begin its takeoff roll

Answer

MTOW is the maximum weight, as certified by the manufacturer and regulator, at which an aircraft is permitted to commence takeoff.

Question 2

What does 'center of gravity' (CG) refer to in aircraft dispatch?

Accepted Answer

The single point at which the aircraft's entire weight is considered to act

Answer

Center of gravity is the balance point of the aircraft's total weight; its position within approved limits is critical for stable, controllable flight.

Question 3

What is zero fuel weight (ZFW)?

Accepted Answer

The maximum allowable weight of the aircraft including payload but excluding usable fuel

Answer

ZFW is the maximum structural weight permitted with no usable fuel, constraining how much payload can be loaded before fuel is added.

Question 4

What is 'useful load' in aircraft weight-and-balance calculations?

Accepted Answer

The difference between the aircraft's maximum gross weight and its empty weight

Answer

Useful load is the total capacity available for passengers, baggage, cargo, and fuel, calculated as maximum gross weight minus empty weight.

Question 5

How does high density altitude affect aircraft performance?

Accepted Answer

It reduces both engine thrust and aerodynamic lift due to lower air density

Answer

At high density altitude, reduced air density lowers engine power output and decreases the lift generated by the wings, degrading overall performance.
