APU fuel burn does not matter

That's not why we want to shut down the engines right away. Rampers routinely forget to check if the beacon is off. They have hearing protection on and walk right up to the spinning engine with a cone that gets sucked in. Happens every couple of years. Only takes one of those events to undo years of your hard work of not starting the APU on taxi in.

Delta's May 2020 bid is a perfect example. On paper, that saved the company money by moving 1,000 more pilots to the 717 pay rates. Saved about $1.5 million a month on payroll. If that's the only thing you measure, then that was a very smart idea. Too bad the unintended consequences have cost Delta way more money than it saved. Wasting time on scaring pilots about APU burn gives our passengers a bad experience for minor fuel savings equivalent to a rounding error.
Here's an unintended consequence from one captain. He didn't like to start the APU until 10 min before push because according to him since he saved the company some fuel at the gate, he thought it was OK to fly at Mach 0.80 instead of 0.78.

We care about safety around the airplane over here and getting the engines secured efficiently after parking is high on the list. Plus an engine at idle
is burning WAY more fuel than an APU would burn running for the entire turn.

I've been here a good chunk of time and I've literally never waited for ground power to be plugged in before shutting down an engine. Every memo I've read, at least on my fleet, is to wait to turn on the APU until approaching the gate. I've never seen one that says to never start it at all.

Measuring with a micrometer and cutting with an axe. How many man-hours were spent researching the fuel savings of removing olives? How many meetings were spent discussing the rollout of that program? How many hours were spent recording the results? Then think about the opportunity cost of using all those employees to save $100,000. Were there other projects they could have been working on that could have saved even more?

It was Gordon Bethune who said you can't manage what you don't measure.

LOTS of “I” and “me” statements coming from this guy. MY passengers and MY FOM…..🙄👎🏻
If I were a betting man, I would say Oofff must have a shiny new stripe on the shoulder and her ego is full throttle now.

nope. No change in stripes any time recently. This is the main forum, so I recognize people who don’t work at the same place I do post here

In my opinion….the passengers pay for a certain level of decency. There are 180 people on board…each of them paid their 50 cents to not sweat their balls off. Compare it to a restaurant that decides to never give their customers refills on their drinks. You charged those people $3 for a soft drink, and you think it’s ok to further gouge them because of “economy of scale”. I think that’s beneath contempt, and I will be keeping THE (not MY) passengers comfortable. They paid for it.
Multiplying $90 by the thousands of flights that are operated sounds like a lot of money to an individual. To a corporation…..it’s a line item. The simple fact that it’s a CONTROLLABLE cost is why we are told to monitor it. These companies waste money hand over fist for other things that yield little to no ROI….yet we are supposed to make our customers suffer because they are already captive to the situation? Nope.
