Fellow builders / flyers,
I've shared several KR / flying poems with fellow netters over the
years. There are several more aviation inspired poems as well as a
nearly complete 40 year collection of my writings including
"observations on LIfe" such as "Be kind to everyone. No one got to pick
I have the Great Plains 2180 with a Prince P tip prop (52x48) and it burns 4.0
US gallons per hour.
So Larry’s calculation is correct.
My header tank holds 10 US gallons so I usually flight plan for 2 hours with 30
minute reserve .

Rather than "looking it up", perhaps actual measurement is in order.
I have the great planes 2180 with a rayjay turbo. I set up a graduated
container, with calibration marks as the test fuel tank, and ran the motor
at full power, while measuring the actual consumption.
Certainly other methods of
I am preparing for my aircraft certification and one of the items on the DAR
checklist is a fuel flow test for take off fuel consumption. I have a Great
Plains VW 2180 engine. No luck finding anything online. Does anyone have a fuel
flow chart/ graph showing consumption rate for takeoff? Ref. 81
