Thrust Terminology
TAKEOFF THRUST Maximum thrust possible during takeoff.

CONTINUOUS

EGT GAUGE
Exhaust Gas Temperature Gauge indicates temperature of the gases
at the outlet of the gas producer turbine rotor.

Airplane Performance and Flight Planning Terminology
CLIMB
GRADIENT
The ratio, in the same units, and expressed as percentage of:
Change in height
Horizontal distance travelled in the same time interval
DEMONSTRATED
CROSSWIND
VELOCITY
The demonstrated crosswind velocity is the crosswind component for
which adequate control of the airplane during takeoff and landing
was actually demonstrated during certification tests. Is not
considered a limitation.
(f)
Weight and Balance
REFERENCE
DATUM
An imaginary vertical plane from which all horizontal distances are
measured for balance purposes.
ARM
The horizontal distance from the reference datum to the center of
gravity (C.G.) of the item.
MOMENT
the product of the weight of an item multiplied by its arm. (Moment
divided by a constant is used to simplify balance calculations by
reducing the number of digits).
CENTER OF
GRAVITY (C.G.)
The pint at which the airplane would balance if suspended. Its
distance from the reference datum is found by dividing the total
moment by the total weight of the airplane.
C.G. ARM
The arm
obtained by adding the airplane’s individual moments and
dividing the sum by the total weight.
C.G. LIMITS
The extreme center of gravity locations within which the airplane
must be operated at a given weight.
USABLE FUEL
Fuel available for flight planning.
