Airplane Performance & Flight Planning Terminology; Meteorological Terminolqgy - Mooney M20J Pilot Operating Handbook

SECTION I
GENERAL
MOONEY
MODEL M20J
Mixture Provides a mechanical linkage to fuel injector mixture
Control control to control size of fuel feed aperture,
therefore the airifuel mixture. It is primary method
to shut engine down.
EGT
A temperature measuring system that senses EXHAUST
GAS TEMPERATURE (EGT) in the exhaust pipe. The EGT
gauge is the primary indication for mixture leaning in cruise
flight at
75%
power or less.
Tachometer
Instrument that indicates engine rotational speed.
Speed is shown as propeller revolutions per minute
(RPM).
Propeller
Device that regulates RPM of enginelpropeller by
Governor increasing or decreasing propeller pitch through a
pitch change mechanism in propeller hub.
AIRPLANE PERFORMANCE AND FLIGHT PLANNING TERMINOLOGY
Demon- The ?lelocity of the crosswind component for which
strated adequate control of the airplane during takeoff and
Crosswind landing Velocity test was actually demonstrated
during certification The value shown is not considered to
'
limiting.
g Acceleration due to gravity.
Service The maximum altitude at which aircraft at gross weight
Ceiling has the capability of climbing at the rate of
100
ftlmin.
Unusable Fuel remaining after a runout test has been completed
Fuel in accordance with governmental regulations.
Usable Fuel available for airplane propulsion.

METEOROLOGICAL TERMINOLOGY
AGL Above ground level.
Density Altitude as determined by pressure altitude and Al-
titude existing ambient temperature. In standard atmosphere
(ISA) density and presure altitude are equal. For a given
pressure altitude, the higher the temperature, the higher
the density altitude.
