AIRPLANE DESCRIPTION
Engine Fuel Ignition
Dual self-powered electronic ignition drive two spark plugs in each cylin-
der. The system is denominated as Magnetos, as it mimics the typical func-
tionality of mechanical magnetos. Normal operation is conducted with both
magnetos, as more complete burning of the fuel-air mixture occurs with dual
ignition.
Engine Exhaust
The exhaust system consists of four exhaust headers, a muer and a tail-
pipe. All of it’s components are made of titanium, making it very light weight.
The tailpipe is directed downwards at a 45 degrees angle relative to the
aircraft’s roll axis, thus decreasing the possibility of any CO finding to enter
into the cabin.
7.6.3 ENGINE OPERATING CONTROLS
Engine controls are easily accessible to both pilots on the center console.
They consist of a single-lever throttle control and the choke lever.
Throttle Lever
A throttle control lever is located in the central console and controls engine
power. The lever acts upon two cables which control the throttle valves of
the two carburetors. A wire, which is operated by the choke handle, actuates
the choke shaft of the respective carburetor, to provide assistance with cold
starts. The engine is not equipped with a carburetor heat device because
the carburetor air inlet position inside the engine cowling grants a suciently
warm air temperature in any condition.
Start button
A push-type button, located on the main switch panel, activates starter oper-
ation. The button is labeled START.
Magnetos/ignition switches
The two ignition circuits are indipendently activated by two switches posi-
tioned on the switch panel and designated MAG L and MAG R. Normally, the
engine is operated on both magnetos (both switch OP) except for magneto
checks and emergency operations.
