WARNING !
The controls are very sensitive, this being why we recommend frictions on the
three controls. Fully unscrew and re-screw 6 threads the lateral frictions and 11
threads the pitch friction.
The collective is also of the classical type with a throttle twist grip. A correlator activates
the throttle in relation to the collective position but a fine adjustment is still necessary
using a
servo-motor called a
“governor”
.
The governor acts as a « cruise control » and allows the pilot to avoid having to
constantly adjust the throttle to maintain engine and rotor RPM. The governor is a
standard equipment on the H3.
The governor operates on the
pilot’s throttle control and gathers its information from
the probe of the rotor rev-counter.
During take-off and climb, for more power, the governor is engaged at 5800RPM.
Later, during the flight, the governor can be slowed down to 5500RPM.
There are two different types of governors :
➢
Variable governor
Keeps the RPM selected by the pilot at the moment is has been switched on. It is thus
possible to fly at any selected RPM.
➢
Pre-selected governor
Keeps 5500 RPM or 5800 RPM. If the governor is switched on at other regime, the
governor will stabilize at the nearest pre-selected RPM.
NOTE
Takeoff with a failed governor is possible but the pilot must control the throttle
himself to maintain 100% rotor RPM until after landing. Do not fear LOW or HIGH
RPM. The total RPM acceptable zone ranges from 450 to 600 rotor RPM.
NOTE
Since June 2016, a new governor has been introduced. It is a pre-selected
governor 5500/5800 RPM. The RPM is controlled by a switch on the cyclic. In
addition, a slow motion push button is added for slowing down the regulation of
the governor during descent, enabling the pilot to keep the governor ON during
descent, if needed.
