1.6.3 Mass and Balance
RP Reference Plane, an imaginary vertical plane which forms the
origin for all center-of-gravity calculations
MAC
Mean Aerodynamic Chord
MTOM
Maximum Take-Off Mass (cf. MTOW)
Empty Mass Mass of the Airplane including non-useable fuel, all operating-
fluids and max. amount of oil. It does not contain payload and
trip-fuel and fuel-reserves.
Center-of-
Gravity
Imaginary point, at which gravity acts on the aircraft
Lever Horizontal distance between the center-of-gravity of a body and
the reference plane
Moment
Product of Mass and Lever of a body
Non-useable
Fuel
Fuel which remains in the tank and is not available for the flight
Useable Fuel
Amount of fuel which is available for the flight
Payload
Difference between empty-mass and take-off-mass
NLP
