Chirping Alarm

[manofmac]

HI,

 

I have a "Chirping Alarm" which goes off, usually, just at touch down but today it started on approach when I disconnected the Auto Pilot.

 

It chirps 8 times and repeats with a, approx, 1 second gap.

 

I can find nothing in the manual and cannot turn it off.

 

It even stays on after shutting down the engines.

 

Any ideas?

 

thanks

Press the red button on the yoke.

Thanks for that.

 

As a matter of interest, what does the alarm signify?

Autopilot disconnect.

Well, DUH!  (slaps forehead in disgust!)

 

I guess that should have been obvious.

 

Thank you

FYI: from the supplied SAAB 340A Systems pdf page 194:

 

A/P Disconnect Pushbuttons

 

When either A/P Disconnect button is initially pressed, the autopilot and yaw damper disengage, the AP 

 

and YD engage levers return to the DISENGAGED position, and a red AP and a yellow YD annunciator in 

 

a box flash on each EADI. Also, when the autopilot disengages, an aural warning (cavalry charge) sounds. Pushing the button a second time stops the flashing, changes the AP annunciator to white, and 

 

removes the YD annunciator.
