Hi, I was wondering if an aural warning(annoying buzz) sound that comes up as soon as the electrical power is turned on, is supposed to stay on all throughout the flight. If not, how can I fix the problem? Many thanks in advance for your help,regards,Mac

Mac,are you using the Project Tupolev Tu-154 or the one here in the library ? Are your throttle levers in idle position if you switch the power on ? Then later, is your "no takeoff" warning light really out ?Michael

Michael, I am using the Project Tupolev from Avsim.ru. (With latest Update, I beleive is 9.3 or so, for FS9) The throttle levers are at idle before turning the electrical (battery) on. I am also following the manual and by the time I move the engine stop levers to forward (engineer's panel), the electrical system is already on. At the beginning of the takeoff run, I make sure the nosewheel steering is in the 10 deg limit operating mode, which puts out the "No Take-off" warning light. I still get the annoying sound, although somewhat muted from the engine sounds. Thanks for your help,regards,
