Airplane Manual FK 9 ELA FK Lightplanes
Revision 4 Limitations page 2-5
Spinning any aircraft which is not certified for this maneuver is extremely
dangerous! The onset of a stall is indicated to the pilot by many factors like
IAS, stick pressure, horizon level. Stalls can also be result from abrupt
control deflections / changes in angle of attack!
In strong turbulence the airspeed must be reduced below V
A
(151 km/h).
When flying off grass strips with long grass, the wheel pants must be
removed to avoid damage.
When flying with doors removed, maximum speed is 100 km/h. Flight with
door open is prohibited.
Maneuvers with zero or negative load factors must be avoided under all
conditions. These maneuvers may cause a fire due to fuel spill when using
ROTAX engines with carburetors.
