SECTION 4
CABRI G2
NORMAL PROCEDURES
4-17
Training
Caution
: The Cabri G2 has a very capable rotor, giving her comparatively
permissive autorotation characteristics. This allows efficient
training and practice, from different situations and using different
piloting techniques.
Following procedures are given as guidelines and should be
followed for best safety.
However, pilot and instructor should keep in mind that power
failure training is a very demanding practice, requiring a high
level of awareness, good health and personal condition, and
aircraft in perfect airworthy state.
Power failure practice must be limited to the strict needs of
instruction and maintaining good proficiency. Never practice
autorotation as a show.
Pilot must stay familiar with Height-velocity diagram page 5-3 together with
procedures described in Section 3 to follow them in case of an actual
failure.
Autorotation must only be practiced over an area that would minimize
hazards associated with an actual engine failure.
Smooth and hard surface should be preferred to practice running landings.
In order to familiarize with Cabri G2 landing attitude, practice powered
running landings before autorotation training.
Caution
: Before attempting running landings, check thoroughly carbide
wear shoes. An unexpected drift during a running landing is a
clue to a carbide shoe failure. Always check in case of doubt.
Rapid throttle chops should not be used to practice autorotation.
During autorotation training, try to keep the helicopter skids level
at touchdown, to avoid unpleasant pitch-down and bouncing.
If the ground is not smooth and if the rotor speed is too low when
the helicopter touches the ground, a pitch oscillation can happen,
leading to an uncomfortable landing. In that case, the pilot has to
keep the cyclic control in the neutral position in order to prevent
induced oscillations.
