Was that You in IFD ex KG, one day, on climb to FL's, when the #@*& heater wouldn't work, and you were *$#^ freezin', so you returned to KG., and when you called 'On descent inbound', you 'was politely informed' that we already KNEW THAT, as your mic was 'open' ....and had been for the whole of the climb..??
We knew all about the status of your *&#@ heater.....and your feet!!
Cheers
