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.

Takeoff Power
Maximum
Continuous
Power (MCP)
Idle Power
The maximum power permissible for takeoff (may be time limited).

EGT Gauge
TIT Gauge
Tachometer
The lever used to control engine power, from the lowest through
the highest power, by controlling the air and the fuel flow. The extreme
lever positions are called OPEN (forward position) and
CLOSE (aft position).
The lever used to select the propeller blade angle of attack. It provides
a mechanical linkage to the propeller governor. In the
FULL AFT position of the lever the angle of attack is high, in the
FULL FORWARD position it is low.
The mixture control provides a mechanical linkage with the mixture
control valve of the fuel control unit, to adjust the air/fuel
mixture. It is also a primary means to shut down the engine. The
most forward position of the mixture control lever is called
RICH, the aft position is called IDLE/CUT-OFF.
The exhaust gas temperature indicator is the instrument used to
identify the lean fuel flow mixtures for various power settings.
A temperature measuring system that senses exhaust gas temperature
at the turbine inlet.
An instrument that indicates rotational speed. The speed is shown
as propeller revolutions per minute (RPM).
