Description of Airplane and Systems EXTRA 500
ENGINE START
The ENGINE START (ignition) switch is normally set to
IGN OFF position if aircraft is on ground and engine shut down.
During normal flight and under normal flight conditions, the
ignition switch can also be set to
IGN OFF position.
During start and landing and during critical flight conditions
such as severe weather (e.g. heavy rain and others) the ignition
switch should be set to
IGN, which guarantees “continuous”
ignition and minimizes possible engine flame out.
Generally during flight and under consideration of the above
mentioned, the ignition switch should be set to
IGN OFF
position to minimize wear and tear of spark plug.

Engine Switches
Note Engine starting can also be performed using external power
from a ground power unit (GPU), described in Section 4 of
this POH.
7.14.l Engine Air Intake
Engine air intake is located at front lower section of the engine
cowling. Two separate engine inlet heating devices, one for
engine external and one for internal heating are installed. The
external air inlet heating is heated with exhaust gas while the
internal, which is the first stator ring of the engine compressor,
is heated with bleed air. Both devices are activated
simultaneously via a Bowden cable, located in the center
console. The engine part is activated with a micro switch
located in the right exhaust stack (activated by Bowden cable
