9.3.2
Idle Check
Fully close the throttle and note rpm; it should be 2,500 RPM ± 100 RPM. Adjustment, if
required, is by the throttle stop screw on the throttle body. For method, and precautions, see
the aircraft manufacturer’s manual.
9.3.3
Stopping the Engine
It is usual to idle the engine for 2 to 3 minutes before stopping (to dissipate internal heat prior
to shut down) [see aircraft manufacturers operating manual].
Switching off either the ECU power, or ignition switches, or the fuel pumps will stop the
engine. The latter gives a short run down and dissipates pressure in the fuel lines.
9.4
Power Loss at Altitude
Performance at altitude is degraded due to a reduction in air density. The approximate power
available (at given RPM / throttle setting) is given in 6.2.1 for Sea Level.
