Wind
The wind velocities recorded as variables on the charts of
this handbook are to be understood as the headwind or
tailwind components of the reported winds.
ENGINE POWER & CONTROLS TERMINOLOGY
BHP
Brake Horsepower
is the power developed by the engine.
MP
Manifold Pressure
is the pressure measured in the intake
system of the engine and is depicted as inches of Hg.
MCP
Maximum Continuous Power
is the maximum power for
abnormal or emergency operations.
Maximum Cruise Power
The maximum power recommended for cruise.
MNOP
Maximum Normal Operating Power
is the maximum
power for all normal operations (except takeoff). This
power, in most situations, is the same as Maximum Contin-
uous Power.
Mixture Control
The
Mixture Control
provides a mechanical linkage with
the fuel control unit of fuel injection engines, to control the
size of the fuel feed aperture, and thus, the air/fuel mixture.
It is also a primary means to shut down the engine.
Propeller Control
The lever used to select a propeller speed.
Propeller Governor
The device that regulates the RPM of the engine and
propeller by increasing or decreasing the propeller pitch,
through a pitch change mechanism in the propeller hub.
RPM
Revolutions Per Minute
is a measure of engine and/or
propeller speed.
Stall Strip
Small triangular strips installed along the leading edge of
an airplane wing to disrupt the airflow at high angles of
attack in a controlled way. The strips improve stall
characteristics and spin recovery.
Tachometer
An instrument that indicates propeller rotation and is
expressed as revolutions per minute (RPM).
Throttle
The lever used to control engine power, from the lowest
through the highest power, by controlling propeller pitch,
fuel flow, engine speed, or any combination of these.
