A supply te mpe rature above the reported value indicates a mechanical or
electronic problem. Do not fly until the problem is identified and resolved.
At temperatures below 15°C with particular environmental conditions, frost may
form and impact negatively on the butterfly valve.
With temperatures below 0° C it can be difficult to start the engine if the battery is not fully
charged. If necessary, for cold starting, it is possible to connect a fully charged second battery in
parallel to the one installed on the aircraft.
The minimum temperature required for ignition must be understood for a cold
engine.
B.7.1.8. Load Factor
The operating limits of the engine to contingency are due to the need to allow adequate lubricant
to the mechanical action. The fuel injector system is instead substantially insensitive to the
conditions of contingency.

B.7.1.9. Inclination Angle
Similar as to what is described for the load factor, the limits on the angles of inclination of the
engine with respect to the horizontal position are to guarantee adequate lubrication to the
mechanical action.

The angles are referred to the condition of minimum and maximum oil levels. On the pitch axis it
consider a positive angle when the flange propeller pull up; on the roll axis it’s consider a positive
angle when the side # 1 to rotate downward.
These angles should be interpreted as angle of skidding relative to the direction of flight: in case
the angle is accompanied by a centrifugal force implicit in maneuvers coordinates, the angles of
inclination may also be more.
