What is the maximum allowable takeoff weight (MTOW) of an aircraft?
Answer: The maximum certified weight at which an aircraft may begin its takeoff roll
MTOW is the maximum weight, as certified by the manufacturer and regulator, at which an aircraft is permitted to commence takeoff.
What does 'center of gravity' (CG) refer to in aircraft dispatch?
Answer: The single point at which the aircraft's entire weight is considered to act
Center of gravity is the balance point of the aircraft's total weight; its position within approved limits is critical for stable, controllable flight.
What is zero fuel weight (ZFW)?
Answer: The maximum allowable weight of the aircraft including payload but excluding usable fuel
ZFW is the maximum structural weight permitted with no usable fuel, constraining how much payload can be loaded before fuel is added.
What is 'useful load' in aircraft weight-and-balance calculations?
Answer: The difference between the aircraft's maximum gross weight and its empty weight
Useful load is the total capacity available for passengers, baggage, cargo, and fuel, calculated as maximum gross weight minus empty weight.
How does high density altitude affect aircraft performance?
Answer: It reduces both engine thrust and aerodynamic lift due to lower air density
At high density altitude, reduced air density lowers engine power output and decreases the lift generated by the wings, degrading overall performance.
What does the aircraft 'flight envelope' define for dispatch planning?
Answer: The approved boundaries of weight, balance, speed, and structural loading for safe operation
The flight envelope defines all operating limits — structural, aerodynamic, and performance — within which the aircraft can be safely dispatched and flown.
