It doesn't go off until I'm at about 35 MPH after landing during the roll out. It doesn't sound at all during an approach to stall or during the stall. I know that there are two different adjustment points, one on the face of the ASI and one on the stall warning control board, but is would sure be nice to know what the procedure for adjust is instead of trying to adjust it hit or miss. Thanks, Larry Allegro 2000 N4362C Read this topic online here: http://forums.matronics.com/viewtopic.php?p=353506#353506 ________________________________ Message 2 _____________________________________ Time: 07:36:05 AM PST US Subject: Allegro-List: Re: Stall Warning Adjustment From: "aerosiam" Larry I have the same problem. It sounds after touchdown. The system worked normally for a couple of years so i am not sure an adjustment will cure your problem. Presumably you already checked that the sensor tube is not blocked.

I was thinking that the pressure switch may have lost some of it's effectiveness over the years and could be adjusted. But maybe not. It may require the replacement of circuit board.

It does sometimes sound just after touchdown with the nosewheel up, but when doing stalls I am focused on coordinated flight and aerodynamic cues, so maybe wouldn't notice the lack of the buzzer. Will have to try that out this weekend if the wind dies down from todays 30 kts. 807 hours TT and about 8 years on my Allegro. Will be interesting to see if there is a stall warning problem that happens on Allegros after they fly several hundred hours and a few years of age. ...brad Bismarck ND.
