Power Plant
hp Horsepower
kW Kilowatt
Takeoff Power
Maximum engine power for takeoff.
Maximum Continuous Power
Maximum permissible continuous engine output power during flight.
Flight Performance and Flight Planning
Demonstrated Crosswind Component
The maximum speed of the crosswind component at which the maneuverability of the aircraft
during takeoff and landing has been demonstrated during type certification test flights.
Service Ceiling
The altitude at which the maximum rate of climb is 100 fpm / 0.5 m/s.
Weight and Balance
Reference Datum (RD)
An imaginary vertical plane from which all horizontal distances for the center of gravity calculations are
measured. The Reference Datum is located 1.975 m / 77.76 in forward direction from inner surface
of the firewall, perpendicular to the longitudinal axis of the aircraft.
Station A defined point along the longitudinal axis which is generally presented as a specific distance
from the reference datum.
Lever Arm The horizontal distance from the reference datum to the center of gravity (of a component).
Moment The weight of a component multiplied by its lever arm.
Center of Gravity (CG)
Point of equilibrium for the aircraft weight.
CG position
Distance from the reference datum to the CG. It is determined by dividing the total moment
(sum of the individual moments) by the total weight.
Center of Gravity Limits
The CG range which an aircraft with a given weight must be operated within.
MAC Mean Aerodynamic Chord
Usable Fuel
The amount of fuel available for the flight plan calculation.
Unusable Fuel
The amount of fuel remaining in the tank, which cannot be safely used in flight.
Empty Weight
Weight of the aircraft including all operating fluids and maximum oil amount without unusable fuel.
Basic Empty Weight
Weight of the aircraft including all operating fluids and maximum oil amount with unusable fuel.
Useful Load
The difference between takeoff weight and empty weight.
Maximum Takeoff Weight
Maximum weight permissible for takeoff.
