Probst B-727: can't make the intermittent horn stop!

[Noel 4,502]

From the manual, I guess you need your stab trim in the green zone, your flaps at 5-25, and I think it said your speed brake off. Where's the speed brake--this is what seems to be deployed and I'm not seeing how to undeploy it?!Noel

Hi there,click on the airplane symbol below the vertical white, amber, blue marker beacon lights and the throttle stack should appear. Just to the left of the number 1 engine throttle is the speedbrake (or spoiler) lever. Make sure it is all the way forward.Or you can use your keyboard instead and type # (pound key). This will either extend or retract the spoilers.Hope this helps.

Make sure you do not arm speed brakes (for RTO). Just let them in the full DOWN position.
