A/C and helicopter have and indicated speed at the top of the screen.
PROBLEM : This speed is a GROUND SPEED ( GS ). If you use script of wind effects with aircraft you will be able to stall with FULL THROTTLE. Only because the reference is GS !
PROBLEM N°2 : The contrary to the stall, at high speed (back wind) helicopter have a very low control (it is GS not Indicated speed so the control should stay the same)
PROBLEM N°3 : As Problem n°2 when you turn in direction of the wind you have have some difficulty to turn. Same origin of problem like n°2.
SOLUTION : You should use INDICATED SPEED AS REFERENCE ! IT is not normal to stall with full throttle (+ afterburner) with front wind.
EDIT : This kind of script allow people to turn ON wind effect to paratroopers and to paradroping box.
Updated, because there is several issues due to the wrong reference.
stall / can't move with air mass / wrong turn / wrong power / wrong control with wind / Wond landing / wrong hover possibility with helicopter
