Introduction
This Section provides description and operation of the propulsion
systems.
7.2
Cockpit controls
Cockpit Ventilation
During powered flight, front ventilation valve in centre of the spinner,
should be opened. This is important as during powered flight,
especially at high power settings, motor needs sufficient amount of
cooling air. On the instrument panel, close to the handle which
operates ventilation valve, is a sticker, which clearly identifies in
which position of control handle, ventilation is opened.
When is pushed
forward
, than ventilation is
opened
! Also from amount
of air coming into cockpit and its noise, is quite evident to the pilot if
ventilation is opened or not. So there is no indication on FCU about
position of ventilation lever, however FCU instrument monitors how
quickly motor temperature is rising in time. If motor temperature
rising is faster than it is usual, then pilot gets red warning message
“Check ventilation”.
Throttle control
Throttle is controlled via FCU instrument unit rotating knob. Rotate
the knob in clockwise direction to increase motor power and
counterclockwise to degrease motor power or stop the motor.
Detail information about FCU instrument operation there are listed
in
FCU Instrument manual
.
WARNING
If temperature of motor is raising too fast, check if ventilation
valve is opened – ventilation lever must be pushed fully
forward!
