Maximum Landing Mass:
The highest mass for landing conditions at the maximum descent velocity.
This velocity was used in the strength calculations to determine the
landing gear loads during a particularly hard landing.
Moment Arm: The horizontal distance from the Datum Plane to the Center of Gravity
of a component.
Moment: The mass of a component multiplied by its moment arm.
Usable fuel: The quantity of fuel available for flight planning.
Unusable fuel: The quantity of fuel remaining in the tank which cannot be used for flight.
Useful load: The difference between take-off mass and empty mass.
(e) Engine
EECU: Electr. Engine Control Unit
RPM: Revolutions per minute (rotational speed of the propeller)
Engine starting fuel temperature:
Above this fuel temperature the engine may be started.
Take-off fuel temperature:
Above this fuel temperature take-off power setting is permitted.
OEI: One engine inoperative
