Gentlemen,
Whether or not this is the proper thread for this particular discussion (though it seems appropriate enough considering it's mostly technical aspects), I dare interject nevertheless.
Propduffer is correct in this instance.
Buzzbox, with due respect, you first agree that the only way to turn off the satellite transmitter/modem from the flight deck is by dropping the left AC bus.
Then, seemingly out of thin air, you disagree all of the sudden and provide no basis for this change of mind, other than to claim that this is 'sensitive information'.
DJ177, with due respect, I feel it unfair to accuse Produffer of a lack of imagination. He has clearly stayed solidly grounded in fact, and the burden is on you or others to factually discredit his claims, which you have failed to do.
