Hi Jan,
You mention this limitation of XP11 making the cockpit bright. However, for me above around 6000ft, the 'light' comes on regardless of the position of the seatbelt sign switch. Someone on the IXEG facebook fan page also mentioned that they are having the same problem. If I am below 6000ft, then everything works as intended.
Is there something I could do to bypass this problem?
Kind Regards
Edgaras
