Concetti Chiave
- BEM (basic empty mass) includes mass of the aeroplane and standard items like emergency oxygen and fire extinguishers.
- DOM (dry operation mass) is the aeroplane's total mass ready for operation, including crew and supplies, but excludes fuel and traffic load.
- OM (operating mass) adds fuel to DOM but does not include the traffic load.
- ZFM (zero fuel mass) is the sum of DOM and TL, excluding fuel, while MZFM is its maximum limit.
- TOM (take off mass) is the aeroplane's mass ready for takeoff, with RTOM being performance-limited, and MSTOM is the maximum for structure.
BEM (basic empty mass) = the mass of an aeroplane plus standard items such as: emergency oxygen, fire extinguisher, oil in engin and unusable fuel fluids
BEM not include usable fuel and not passenger.
DOM (dry operation mass) = is the total mass of the aeroplane ready for a operation (A/M operative), with crew and crew baggage, foods and water
DOM not include usable fuel and traffic load (TL)
OM (operating mass) = DOM + fuel but not include traffic load (TL).
TL (traffic load) = sum of pay load passenger, baggage, and cargo.
Not include any non-revenue load.
ZFM (zero fuel mass) = DOM + TL but not include fuel.
MZFM (maximum zero fuel mass) = maximum mass of an airplane with no usable fuel.
TAXI MASS = RAMP WEIGHT
TOM (take off mass) = is the mass of an areoplane including everiting ready for take off run.
RTOM (regulated take off mass) = is the TOM but performance limitated.
MSTOM (maximum structural take off mass) = is the max structural for take off run.
Payload and MSLM
MSLM (maximum structural landing mass) = is the maximum permissible total airplane mass on landing (normal).
Useful/disposable load = the sum of traffic load (TL) and fuel on board.
Domande da interrogazione
- What components are included in the Basic Empty Mass (BEM) of an airplane?
- What is the significance of the Maximum Zero Fuel Mass (MZFM) in airplane operations?
The Basic Empty Mass (BEM) of an airplane includes the mass of the airplane itself plus standard items such as emergency oxygen, fire extinguisher, oil in the engine, and unusable fuel fluids. It does not include usable fuel or passengers.
The Maximum Zero Fuel Mass (MZFM) is the maximum mass of an airplane with no usable fuel. It is significant because it determines the maximum permissible weight of the airplane when it is loaded with passengers, baggage, and cargo, but before fuel is added.
