EMERGENCY PROCEDURES
RSUK0287_POH_Cavalon Revision 2, Issue Date 24.06.2015 3-4
 Select a suitable landing site from safe altitude, considering slope, wind speed and
direction
 Fly a reconnaissance pattern to check for obstacles, especially power lines, wires,
and cables in the approach and go-around path
 Overfly the landing site to check for obstructions such as fences, ditches, rocks,
height of vegetation, and select most suitable touch-down zone
 Perform a normal approach and touch-down into wind with minimal ground speed
3.8 Flight Control Malfunction
In case of a flight control failure the gyroplane can be controlled with the remaining primary
and secondary controls, including power and trim. An immediate reduction of power, and
corresponding reduction in speed may be necessary to avoid pitch oscillations (phugoid) or
other effects affecting dynamic or static stability. Navigate to a suitable landing site with
wide and shallow turns and approach against the wind.
3.8.1 Engine Power Control / Throttle
Throttle jammed open or max
Navigate to a suitable landing site with the power set. If over safe terrain, magneto switches
may be used to control power. When within gliding distance to the selected landing site,
shut-down engine to perform a power-off landing as per Emergency Procedure “Engine
failure”.
NOTE
In case of a control cable breakage the carburettor will be automatically set to
full throttle position.
Throttle jammed closed
Land as per Emergency Procedure “Engine failure”. Residual power may be used to extend
the glide.
3.8.2 Rudder Malfunction
In case of a stuck or loose rudder, continue flight to a suitable, preferably wide landing site
that allows a landing into the wind. If necessary reduce power to avoid excessive side slip.
Align gyroplane prior to touch-down, using engine torque or lateral control input to the side
where the nose is pointed.
3.8.3 Rotor Head Control
In case of a rotor head control malfunction, control pitch attitude using careful trim input and
power setting. Use rudder for directional control and for shallow turns. In some conditions it
may be appropriate to reduce power/speed in order to avoid phugoid effects or a possible
negative yaw-roll coupling. Approach landing site with wide and shallow turns.
