4.21 Flight under Conditions of Precipitation
The flight through areas of precipitation is challenging for pilot and gyroplane. Rain or other
precipitation can have a negative effect on flight performance of the gyroplane; flight
characteristics can be slightly or in extreme situations drastically affected by rainfall. In
particular the following must be expected:
Reduction in, or loss of sight due to wet and / or misted canopy
Failure or faulty operation of avionics and instrumentation (eg water in the pitot
tube)
Increased wear and tear of some gyroplane components (mainly of the
composite propeller leading edge)
Change of aircraft aerodynamics (mainly under freezing rain)
Small reduction in performance due to wet rotors.
Avoidance of precipitation conditions should be taken into consideration during flight
planning. Should a precipitation area be entered despite correct flight planning, react, if
necessary, according to chapter 3 “Emergency Procedures”.
WARNING
Precipitation is a risk that can be minimized by proper flight planning. Flight
through areas of precipitation should be avoided.
4.22 Flight with Summer Canopy
Depending on customer configuration the gyroplane can be configured with a summer-
canopy, which features opened canopy sides. Before flying with summer canopy any loose
objects must be removed from the cabin or safely stowed.
Removal and installation of the canopy is described in chapter 9-8
NOTE
When flying with summer canopy be aware of the strong air stream outside the
cockpit.
4.23 Engine In-flight Shut-down and Air Restart
The engine should not be stopped in flight deliberately except as part of forced landing
training under the supervision of a qualified flight instructor. If possible, allow the engine to
cool down at 3000 rpm for about 30 sec before turning it off.
Make sure both magnetos are switched back ON and the master switch/starter key has
been turned to OFF and back to ON to be prepared for an immediate engine start-up in
case the manoeuvre has to be aborted.
