The last few Captains I flew with actually take that APU Sheriff crap pretty seriously and I'm getting sick of it. I didn't read the whole memo, but I guess it has to do with not using the APU or something. I usually start start the APU after landing which most of the time is followed by a short lecture about "I don't want the APU Sheriff to catch me", "It's cool outside, so no need for APU", "They can get ground power and air", blah blah... Just because it is cool outside doesn't mean it is cool in the cabin, people want some sort of airflow back there!! I always put myself in the pax shoes pretending I'm sitting back there deadheading and how I would feel. Also, I think you will burn more fuel leaving the engine running at the gate while waiting for ground power. And forget about getting air. We are not mainline! I already got a preview of the winter season, people flying PPAS with 100+ kt. headwinds. Better start increasing the block hour even more Comair! Some of these 25+ year Captains want to make money!
