hi hansmake sure you have the latest patches for the 747. one of them addresses the FLCH issue. Also, make sure both FD's are off.as for the horn, hmmmm. there are numerous sounds that could be occuring. alas, it would be of no help if we can't hear it. can you describe it?possibly, it could be that your flaps are not config? your AP isn't on, or maybe its a glitch. just disengage A/P and re-engage. maybe that will help.good lucktomas
