Ever notice that in the cockpits of some transport aircraft there is an incessant clicking noise when it is powered up. Does anybody know what it is from and what causes it?
I am pretty sure it has to do with the electrical standby AI. I think I was in a 757 sim or on the ground when someone pulled a breaker which I think was the standby AI breaker to stop the noise (obviously it was reset before flight).
Just wondering where it comes from and why it clicks. Thanks!!
