General DA 62 AFM
MET: Weather, weather advice.
NAV: Navigation, route planning.
RoC: Rate of Climb.
(d) Mass and Balance
CG: Center of Gravity, also called 'center of mass'. Imaginary point in which
the airplane mass is assumed to be concentrated for mass and balance
calculations. Its distance from the Datum Plane is equal to the Center
of Gravity Moment Arm.
Center of Gravity Moment Arm:
The Moment Arm which is obtained if one divides the sum of the
individual moments of the airplane by its total mass.
Center of Gravity Limits:
The Center of Gravity range within which the airplane, at a given mass,
must be operated.
DP: Datum Plane; an imaginary vertical plane from which all horizontal
distances for center of gravity calculations are measured.
Empty Mass: The mass of the airplane including unusable fuel, all operating fluids and
the maximum quantity of oil.
Maximum Take-off Mass:
The maximum permissible mass for take-off.
