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
