I was on final approach and elected to perform a go around.  Throttles were at full and gear retracted when the horn cut in and wouldn't quit till I put the year down again on final approach.

The warning horn comes on if the flaps are lowered to Flaps 15 or more and the landing gear is raised. If you had raised the flaps to Flaps 10, the warning horn would have stopped. ;)

Hi,

in Addition, you can silence the horn by clicking the little round button on the right side if the throttle quadrant right beneath the flap selector stick.
You can silence the horn with flaps setting to 25 and gear up. Any flap setting above 25 degrees and gear up condition will result in a warning horn that can only be silenced by gear down. So if you fly a go around and raise the flaps, try the Warnung horn silence button as soon as the flaps are above 25 degrees.

Thanks for that Mathias. While I knew about the Warning Horn silence button, I did not know about this one: Any flap setting above 25 degrees and gear up condition will result in a warning horn that can only be silenced by gear down. I guess that's because if I do a Go Around, I raise the gear, increase the throttle, then raise the flaps to around 5^o, without worrying about silencing the warning horn until I have got everything under control for the Go Around. By then, the horn has gone off due to the flaps being at 5^o. ;D

Hi,

i know, that you were familar with the silence button, it was just in addition for our topic starter  ;)
Yes, the flap and gear logic seems to be very close to the real 737 logic! I think, it is a very simple but useful trick, that Boeing allowed to silence the warning only with flap settings used for approach, but not for landing with a retracted gear. I think there have been enough examples of very very close to runway touch downs in history cause of pilots forgot the landing gear and irgnored reading the check list.  :-[

Horn can't be silence ... That is actually the bug

The only time I couldn't silence the horn was when I had the flaps at 25, or more, and the gear up.
