Can confirm at least for the Helicopters used in the fire-fighter exercise and the one for air control altis multiplayer and the solo mission.

thank you guys :)

seems to be rather an Windows issue, the following steps resolved the issue:

i can can confirm this bug. I have a 3 monitor setup. On first start it was on the middle monitor (my main monitor), where it was supposed to be. After changing Video stuff (fxaa etc.) it was snapping to either left or right monitor but never the middle one. I only could place it on middle monitor in the windowed screen.
