I have recently added the Cessna Citation Sovereign to my list of aircraft. When flying I get a loud buzzing sound (not sure but seems to be associated with the flaps).Could someone please tell me what this sound denotes, and how I can disable it.Any help would be much appreciatedregardsBrian

Does this sound play at all altitudes ? From my expereince it's a sudden warning sound which plays when climbing through 10.000 feet without the cabin pressure system being switched on. The switch(es) concerned is(are) on one of the sub-panels and should be ON or AUTO as part of the plane's startup procedure.Good luckHans
