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

The maximum weight at which an aircraft may land

Answer

The maximum weight permitted during cruise flight

Answer

The maximum weight of fuel that can be loaded

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

The geographic midpoint of the planned flight route

Answer

The center of the aircraft's fuel tank arrangement

Answer

The midpoint of the passenger cabin seating area

Question 3

What is zero fuel weight (ZFW)?

Accepted Answer

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

Answer

The actual weight of the aircraft after all fuel is consumed

Answer

The weight of the aircraft with completely empty fuel tanks

Answer

The minimum operating weight required for dispatch

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

The combined weight of revenue passengers only

Answer

The weight of all cargo loaded in the hold

Answer

The total weight of fuel carried on the flight

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

It increases engine thrust by requiring richer fuel mixtures

Answer

It has no measurable effect on takeoff or climb performance

Answer

It only degrades landing performance, not takeoff

Question 6

What does the aircraft 'flight envelope' define for dispatch planning?

Accepted Answer

The approved boundaries of weight, balance, speed, and structural loading for safe operation

Answer

The aircraft's scheduled maintenance inspection intervals

Answer

The physical dimensions of the aircraft's cargo compartment

Answer

The maximum radio communication range of the aircraft
