EMERGENCY PROCEDURES
AutoGyro_POH_Calidus Revision 4.0 – Issue Date 17.JAN.2019 3-12
3.15 Additional Cockpit Indications
3.15.1 Canopy Indication (if installed)
Refer to emergency procedure “Canopy Open in Flight” and Flight Manual Supplement.
3.15.2 Outside Air Temperature and Rotor Bearing Temperature
The Rotor Bearing Temperature (RBT) indicator is provided for condition monitoring of the
rotor bearing. If, in stabilized conditions, RBT rises suddenly above OAT, have bearing
inspected.
Note; from the introduction of rotorhead III in 2018 the rotor bearing temp display is deleted,
because market feedback determined that this indication provided no useful information. It
is replaced by OAT, with the sensor mounted below the body.
3.16 Loss of Visibility
In case of canopy misting, open air vents and windows to ensure proper ventilation. If the
situation cannot be corrected or occurs suddenly, such as after a bird strike or canopy icing,
maintain safe attitude by visual reference to the sides, using the open sliding window, if
necessary.
When at safe height, stabilize the aircraft at 90 km/h (55mph) and clear the viewing
obstruction by using a hand through the sliding window.
If forward vision is still impaired or lost, continue flight with a left side slip, using the open
sliding window for visual reference. Land at the nearest suitable location and align just prior
to touch-down.
3.17 Recovery System / Rotor System
This gyroplane is not equipped with a ballistic recovery system. However, its rotor system
which is in permanent autorotation serves as such a system. Therefore, the entire rotor
system including its rotor head with blade attachments and the corresponding components
of the flight controls have to be inspected and maintained carefully.
If any undue vibration or unusual behaviour is experienced a precautionary landing should
be considered.
3.18 Rotor Icing
Flight in icing conditions may lead to ice forming on the inner leading edge of the blade (see
photo), leading to vibration and loss of lift performance. This may also be indicated by a
more than normal or constantly increasing power demand. This could ultimately result in a
condition where altitude cannot be maintained, even at maximum power. An iced-up rotor
system can also cause severe vibration. If any of the signs for rotor icing is evident, carry
out a precautionary landing.
Flight in icing conditions is NOT allowed!
