Can someone translate please?

Hi Tomislav,
I think you are trying to describe Strömungsabriss or stall, which is the start of all Trudeln or spins.

Without a stall there is no spin. Yes, an aircraft can stall at all different speeds. The only variable in stalling an aircraft is the angle of attack of the wing. If you exceed the critical angle of attack you stall. And if you stall your aircraft in uncoordinated flight a spin will most likely result. If you keep your controls neutral in a propeller driven aircraft you are most likely in uncoordinated flight since other factors like torque, slipstream, p-factor need to be considered (those are turning inducing aerodynamic forcees).

During steep dives when the pullout maneuver fails it may also have to do with blanking the elevator by the main wing resulting in no airflow over this control surface and consequently rendering it useless.

Sorry, had to go to bat for a fellow pilot, Peter's translation is right on.

Regards,

Norbert
