On the EFIS display in the Socata,the LHS middle button(Nav Sensor Selector) is used to couple the GPS to the auto pilot.If you are running Windows XP,clicking this buttons gives you an instant exit.The No1 System Bearing Pointer Select.in bottom row,gives the same result.Is it possible to use another method to couple the GPS?Sticking pieces of tape on the screen to cover these buttons so I can't click them doesn't seem to work!!!(Just kidding)Rodger.

Rodger,This is a know problem as stated by the ROTW developers in the Socata documentation. They forwarded the problem to TRI. I don't know what the status is though.Best,Mannie

MannieThanks for your reply.What a fabulous aircraft!!Rodger.
