I was pondering this D-0 thingie and how best to identify the rough spots and track them. Different door switches that report separate times was a great idea but then I remembered a long lost item from the past.

At the OLD terminal in DTW, we used to get push clearance over ACARS. When they installed it, it really cut down on the radio traffic. It wasn't moved to the new DTW terminal because it was too expensive to move (so Delete Pete told me one time when I flew with him).

So, if there was an e-record of:
Cabin door closed
Push request sent
Push clearance received
Beacon on/Breakes released
Aircraft moved

I think the powers that be would have a much better picture of whats going on.

Anyway, just throwing it out as a long range solution as we get a fancier system.
