climb with no side slip
4.20 Special Procedure: Slow Speed Sink and Recovery
Reduce power to idle and let speed decrease by gently using aft control stick
Maintain enough forward speed for sufficient rudder effectivity
Rudder will regain effectivity quickly as soon as airspeed or propeller thrust is
increased
To recover, let nose drop slightly below the horizon and build-up air speed while
adding power at the same time
4.21 Flight under Conditions of Precipitation
The flight through areas of precipitation can be challenging for pilots. 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 wind shield or windows
Failure or faulty operation of avionics and instrumentation (eg water in the pitot tube)
Pilot disorientation (especially in snow)
Increased wear and tear of some gyroplane components (mainly of the propeller)
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 areas of precipitation 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 Doors Removed
Before flying with removed doors any loose objects must be removed from the cabin or
safely stowed.
A possible tail shake tendency can be minimized by using a small side slip. In the case
where only one door is removed perform a small side slip into the direction of the closed
door (so that the removed door is on the lee-side).
Removal and installation of doors is described in chapter 9-7
