Ah, the APU police. Sorry for the thread creep. UPS had this brilliant fuel savings plan to not start the APU on block in. MX would plug in ground power so no need for APU. Pilots were to shut the engines down after 90 seconds and wait for ground power if MX wasn't there. Sadly, now the cargo door can't open and the the ramper kids don't get their cans. It's all about the cans. Imagine 10 ramper kids standing around and the K loader guys just staring at the cargo door. Second thing was when they plugged ground power in after the plane went dark. Saw some weird status messages when that happened but we were heading for the crew van at that point.
