GENERAL
ENGINE POWER TERMINOLOGY
BHP
BRAKE HOFSEFOWER
-
Power developed by the engine.
MCP
MAXIMUM CONTINUOUS POWER
-
The maximum power
for takeoff, normal, abnormal or emergency operations.
CHT
CYLINDER HEAD TEMPERATURE
-
Operating temperature of
engine cylinder(@ being monitored by a sensor unit. Expressed in°C
MP
MANIFOLD PRESSURE
-
Pressure measured in the engine's
induction system and
IS
expressed in ~nched of mercury (Hg).
RPM
REVOLUTlONS PER MINUTE
-
Engine speed.
TIT TURBINE INLETTEMPERATURE
-
The exhaust gas temperature
measured at the turbocharger turbine inlet. Expressed in
O F .
Turbocharger
A device used to supply increased amounts of air to an engine
induction system. In operation, the t ~ b i n e i s driven by
engine exhaust gas mixture. The turblne drrectly drives a
compressor which pumps air into the engine intake.
AIRPLANE PERFORMANCE AND FLIGHT PLANNING TERMINOLOGY
Demon-
The velocity of the crosswind component for which adequate
strated control of the airplane during takeoff and landing test was
Crosswind
actually demonstrated during certification. The value shown
Velocity
is not considered to be limiting.
9 Acceleration due to gravity.
Service
The maximum atiude at which aircraft at gross weight has the
Ceiling
capability of climbing at the rate of 100 ftlmin.
ENGINE CONTROLS 8 INSTRUMENTS TERMINOLOGY
Propeller
The control used to select engine speed.
Control
-.
Throttle
The control used to select engine power by controlling MP.
Control
Mixture
Provides a mechanical linkage to the fuel injector mixture
Control
control Control to control the size of the fuel feed aperture, and
therefore the airlfuel mixture. It is the primary method to shut the
engine down.
C H I Gauge
Cylinder head temperature indicator used to determine that engine
operating temperature is within manufacturers specifications.
Tachometer
An instrument that indicates rotational speed of the Engine.
The speed
IS
shown as revolut~ons per m~nute (RPM).
Propeller
The device that regulates RPM of the enginelpropeller by
Governor

METEOROLOGICAL TERMINOLOGY
AGL Above ground level.
Density
Altiiude as determined by pressure atiude and existing
M i u d e
ambient temperature. In standard atmosphere (ISA).density and
pressure atiude are ~ u a l . For a given pressure altitude, the h~gher
the temperature, the hlgher the density altitude.
