For argument sake, 800 airplanes. Let's leave 50 or so out for maint. 750 doing 4 legs/day. 3000 legs each saving 1 minute. 3000 minutes/day or 50hr/day or about 760 days per YEAR of fuel savings.

Too bad ATC can't give accurate edcts and vectors planes around at low altitude for half an hour. Sorta defeats the whole plan.
Then I get to a plane with 3000 lb split in the tanks first thing in the AM. MX sez the GPU was broken.
Argh!

The GPU was broke? Ever heard of cross feeding? Sometimes I wonder about maintenance.

I'm sure. There's a pressure switch that tells the PTU to come on. Sometimes if it's not calibrated quite right, 3000 PSI from the electric pump is not quite enough and the PTU comes on. It's not a pump problem, but a switch problem. Most guys don't even realize this is a problem. Ask about it next CQ.

An APU at 5#s per minute would have had to be running for 10 hours...ouch.

Wish we could do that in the 320....no cross bleed starts for us unless the parking brake is set. I'd like to see that changed. We could shut the APU down and save more $$s

Thanks for sharing your point of view. Let's review our current situation to put your advice in perspective:
APA - 1800+ furloughs
DAL - 0 furloughs, actively hiring.
Now let's review some recent history.*
APA - first to the concession stand in 2003. No snapbacks and no progress over three years of contract negotiation.
DAL - Bankrupt company, $1.3 billion in cash paid to pilots for concessions (ALPA Claim), DAL current wage rates exceed many AMR rates and will exceed all AMR rates in January. DAL pilots own 5.6% of the company (present value $600 million) due to NWA merger. Profit sharing of $90 million booked for this year( note some of that is probably from SE taxi). Reviewing the 2nd quarter corporate numbers, DAL's operating margin and free cash flow looks pretty impressive compared to AMR. I want more, too, but after reviewing the numbers I can really understand why you're "fupm." I'll need some help in figuring out how your "strategy" is going to get you there. I hope your new APA officers can move the ball forward...it'll help all of us.
Again, thanks for sharing!
*We could go back to the "B" scale, or Judge Kendall, or your "strike" for other references if you'd like...

RD, great post, wish more discussions on the subject would be held at UPS. I'd love to hear more on the subject of re-dispatch flight plans and the use of fix balancing to reduce ATC delays...maybe we can get some of those practices at least introduced at my trucking company.

No kidding? Then... wouldn't common sense encourage you to try to avoid such incidences, rather than trying to count them?
I haven't heard one aircraft ask for permission to do cross-bleed starts since the first time oil crossed $70. Any aircraft in front of you should rightfully be assumed to be taxiing SE.

Don't worry about fuel, you guys: I found a Captain trying to send our money directly to outerspace.
I heard a rather short, but eminently rotund captain trying to work a computer and a printer (at the same time!) in JFK. He didn't like the experience. He wanted to ask the dispatcher something, so he says "I'll just call them on SATCOM from the airplane". The other Captain on the flight suggests he just call the dispatcher from the lounge. Stubby says "I can't figure out their phone system: I'll use the SATCOM".
I don't think the APU, or a running engine, can keep up with SATCOM, in terms of cost/minute.
