AIRPLANE PERFORMANCE AND FLIGHT PLANNING
TERMINOLOGY
Climb Gradient – The demonstrated ratio of the change in height during a
portion of a climb, to the horizontal distance traversed in the same time
interval.
Demonstrated Crosswind Velocity – The velocity of the crosswind
component at which adequate control of the aircraft and landing was
actually demonstrated during certification testing. This value is not
considered to be a performance limitation for the aircraft.
g – Acceleration equal to that produced by the force of gravity.
NMPP - Nautical Miles Per Pound – The attainable distance per pound of
fuel consumption.
PPH - Pounds Per Hour – The amount of fuel consumed per hour.
Unusable Fuel – The quantity of fuel which may not be safely used in
flight.
Usable Fuel – The fuel available for engine operation and flight planning
purposes.

WEIGHT AND BALANCE TERMINOLOGY

Arm – The horizontal distance from the reference datum to the center of
gravity (C.G.) of a given item.
Basic Empty Weight – The standard empty weight of an aircraft plus the
weight of any optional equipment.
C.G. - Center of Gravity – The point at which an object (airplane) would
balance if it were suspended. The C.G. distance from the reference datum
is determined by dividing the total moment by the total weight of the
airplane.
C.G. Arm - Center of Gravity Arm – The arm obtained by adding the
airplane's individual moments and dividing the sum of the moments by the
airplane's total weight.
C.G. Limits - Center of Gravity Limits – The extreme center of gravity
locations within which the airplane must be operated at a given weight.
