Thanks Richard: When I load my 727-100 v2.4 the seat belt and no smoking switches are on...No sound until I load it twice then I have to click Off/ On,ON/Off to get the ding. I always start my sim with my default Cessna,engine running at my local airport Copenhagen ( Kastrup) From there I load views..eventual flight and when at the runway I load 727...Twice to get the sounds.
