AIRPLANE PERFORMANCE AND FLIGHT PLANNING
TERMINOLOGY
Demonstrated Demonstrated Crosswind Velocity is the velocity of
Crosswind the crosswind component for which adequate control
Velocity of the airplane during takeoff and landing was actually
demonstrated during certification tests. The value
shown is not considered to be limiting.
9
g is acceleration due to gravity.
NMPG
Nautical Miles Per Gallon is the distance which can
be expected per gallon of fuel consumed at a specific
engine power setting
andlor flight configuration.
PPH
PPH signifies pounds per hour and is the amount of
fuel used per hour.
Usable Fuel Usable Fuel is the fuel available for flight planning.
Unusable Fuel Unusable Fuel is the quantity of fuel that can not be
safely used in flight.
WEIGHT AND BALANCE TERMINOLOGY
Arm Arm is the horizontal distance from the reference datum
to the center of gravity (C.G.) of an item.
Basic Basic Empty Weight is the standard empty weight plus
Empty
the weight of optional equipment.
Weight
Center of
Center of Gravity is the point at which an airplane would
Gravity balance if suspended. Its distance from the reference
(C.G.)
datum is found by dividing the total moment by the total
weight of the airplane.
C.G. Arm
Center of Gravity Arm is the arm obtained by adding the
airplane's individual moments and dividing the sum by the
total weight.
