APU fuel burn does not matter

My APU usage has always been determined by how environmentally conscious the destination is about climate change. I respect the local citizens, and their freely elected city planners. I research the population’s wokeness, then plan accordantly. Don’t ask; my wokeness scale is proprietary.

You could just be like American and make whatever delays you have worse by never hooking up GPU or air then adding time after the plane has already been fueled. And sitting there with your apu running and burning so much fuel that you go under load. But hey as long lazy ground crews and people in the fuse lodge are happy. That is all that matters. Maybe tell your ground crews to hook up that air and electric and shut the apu off until it's close to time unless you don't mind the delay from having to call for a top off. Maybe the director of ops might take umbrage to using that extra fuel when the GPU and gate air are cheaper.

While most pilots have reached the point where they are sick of sweating while they wait for pushback, some still think that starting the APU early is putting a burden on the company. Most APUs burn 200-250 lbs per hour under full load. That's 31-39 gallons per hour. Over the last 5 years, Delta's average jet fuel prices have ranged from $1.05-$2.40 per gallon. That means to cool the airplane during a 1-hour turn costs between $32.55 and $93.60. Keep in mind that GPUs and ground air also cost money. Odds are your airline is wasting more money by understaffing ground crews forcing multiple planes to wait with engines and APUs running before they can block in. The moral of the story is don't feel guilty about starting the APU 20 minutes earlier than you normally would.

And has that stopped hot cabins? Has that prevented Delta from including training material about how to reduce APU fuel usage and that we should only start the APU after we have asked ops to make the ground air colder? By the time a ramper adjusts the ground air, it's way too late. Up until recently, the training center taught new hires to wait for the pre-push message before they start the APU.
