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.  :-[
