2.8. Maneuvers
The FK 9 is certified as an Ultralight aircraft.
Acrobatic maneuvers, including spins, bank angles greater than 60°, as well
as IFR and VFR night are prohibited.
Note regarding spins:
In the light aircraft/ultralight category spinning is
strictly prohibited and is not required to demonstrate during flight test
program.
Despite this, all FK aircraft have also been tested regarding their general
spin characteristics. In general it is important to know that a spin is a very
complex flight condition and relates to many individual factors like weight,
centre of gravity, mass distribution, aerodynamic conditions, number of spin
turns already performed, kind of control deflections already made and so on.
For example, the spinning characteristic of the same aircraft on the same
day can differ significantly because of differences in mass distribution or dirt
on surfaces. This can cause a “non recoverable” spin-condition!
In practice this means that flying into stalls on purpose must be avoided and
recovery procedures have to be performed immediately!
