First of all thanks for the great free-ware panel for the BAe-146. ONe thig I sepecially like is when you look Right and left you display cockpit images, not a huge thiong but it is the small things that all add up.
I have one problem however - when I shutdown the engines, and annoying buzzer turns on. I've tried toggling the AP master, but this doesn't seem to stop it all that I can do is load another plane and then go back to the Bae146
Thank you very much for your posting and the compliment about my BAe panel. I'm very happy that you like it. Unfortunately I could not post here sooner because I was on a holiday trip last week.
What you wrote about the buzzer sounds not good. My current version 3 panel just contains the sounds for the GPWS and some minor click sounds, so unfortunately I don't know from where this sound is at the moment. Have you checked the aircraft sounds? Maybe it's a sound from the aircraft soundset you are using. The best way to check this is to play the sounds from the aircraft sound folder. Just listen to them and compare them with the buzzer sound.
