AIRPLANE FLIGHT MANUAL
AIRPLANE PERFORMANCE AND FLIGHT PLANNING TERMINOLOGY
Demonstrated
Crosswind
Velocity
The velocity of the crosswind component for which adequate control of the
airplane during take off and landing test was actually demonstrated during
certification. The value shown is not considered to be limiting.
g
Acceleration due to gravity.
Service
Ceiling
The maximum altitude at which aircraft at gross weight has the capability
of climbing at the rate of 100 ft/min.
ENGINE CONTROLS & INSTRUMENTS TERMINOLOGY
Propeller
Control
The control used to select engine speed.
Throttle
Control
The control used to select engine power by controlling MP.
Mixture
control
Provides a mechanical linkage to the fuel injector mixture control to control
the size of the fuel feed aperture, and therefore the air/fuel mixture. It is
the primary method to shut the engine down.
CHT
Gauge
Cylinder head temperature indicator used to determine that engine operat-
ing temperature is within manufacturers specifications.
Tachometer
An instrument that indicates rotational speed of the engine. The speed is
shown as propeller revolutions per minute (RPM).
Propeller
Governor
The device that regulates RPM of the engine/propeller by increasing or
decreasing the propeller pitch, through a pitch change mechanism in the
propeller hub.
METEOROLOGICAL TERMINOLOGY
AGL
Above ground level.
Density
Altitude
Altitude as determined by pressure altitude and existing ambient tempera-
ture. In standard atmosphere (ISA) density and pressure altitude are
equal. For a given pressure altitude, the higher the temperature, the higher
the density altitude.
Indicated
Altitude
The altitude actually read from an altimeter when, and only when baromet-
ric subscale (Kollsman window) has been set to Station Pressure.
ISA
INTERNATIONAL STANDARD ATMOSPHERE assumes that
1. The air is a dry perfect gas;
2. The temperature at sea level is 15 degrees Celsius (59
o
F);
3. The pressure at sea level is 29.92 inches Hg (1013.2 MB);
4. The temperature gradient from sea level to the altitude at which the
temperature is --56.5
o
C (--69.7
o
F) is --0.00198
o
C (--0.003564
o
F) per foot.
OAT
OUTSIDE AIR TEMPERATURE -- The free air static temperature, obtained
either from in--flight temperature indications or ground meteorological
sources. It is expressed in
o
C.
Pressure
Altitude
The indicated altitude when Kollsman window is set to 29.92 In. Hg. or
1013.2 MB. In this handbook, altimeter instrument errors are assumed to
be zero.
Station
Pressure
Actual atmospheric pressure at field elevation.
