Reduce power. If condition cannot be corrected, have
maintenance action performed prior to next flight.
Lower
limit
If combined with other indications, such as rising oil
temperature or unusual engine behaviour, shut-down
engine and perform a power-off landing as per
Emergency Procedure “Engine failure”.
Otherwise, monitor engine instruments carefully and
land as soon as practicable. Have maintenance action
performed.

Investigate on landing, there is no flight safety effect
Lower
limit
This may indicate low fuel, (especially if the indication
drops to zero), or filter blockage. The two fuel pumps
have their own filters, so turn on pump two and note
pressure increase. An increase will indicate blocked P1
post pump filter. No change will indicate a pre pump
filter issue. If the engine is running, continue to fly. If
insufficient fuel pressure make a precautionary landing.
3.11 Outside Air Temperature and Rotor Bearing Temperature
Outside Air Temperature (OAT) and Rotor Bearing Temperature (RBT) indicators are
provided for condition monitoring of the rotor bearing. Both readings should be more or less
equal. If, in stabilized conditions, RBT rises suddenly above OAT, have bearing inspected.
OAT is also indicated within the Aspen PFD (where fitted).
3.12 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 50KIAS and clear the viewing obstruction by
using a hand through the sliding window or from the inside.
If forward vision is still impaired or lost, continue flight in a side slip, using the open sliding
window for visual reference. Land at the nearest suitable location and align just prior to
touch-down.
3.13 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.
