Gear Horn Issue

[hew]

Got rid of the noise of the gear warning horn. One of the throttle body switches had an intermittent fault which didn't show up on ground testing but then did so in the air and occasionally went away. While waiting for a new microswitch we simply bypassed the microswitch allowing the other engine to provide the gear-up throttle closed warning. If we had just disconnected the ground from the warning noise box we would have lost all warning sounds. Nevertheless, I had trouble hearing the horn anyway as I have good noise cancelling headsets!
