Other equipment
Pitot - Static system
The Pitot tube is non-heated. It is located under the helicopter belly.
The static port is located just aft of it.
Engine governor
An electric engine governor helps the pilot control the engine speed.
When engaged, it acts on the twist grip to control throttle.
Once switched-on, the governor engages above 2000 RPM (NR =
400 RPM), and self-disengages below.
The pilot can disengage it by two ways :
•
Using the GOV switch located on the tip of the collective stick.
The GOV OFF light then comes on,
•
Forcing the twist-grip to NM = 2000 RPM, for an engine failure
simulation.
At any time, a friction clutch in the governor motor enables the pilot to
overtake it by acting on the twist grip. The pilot can easily disengage the
governor while overtaking its action.
