Flight to Moab Mr. Brunner would like to do some rock climbing in near Moab Utah. You will use the COMANCHE PA 24 -250 performance data chart attached to determine time enroute and fuel costs for a no wind flight. I'll fly the Comanche at 75% power optimum at the chart posted crusing speed at 9500 msl altitude. Airnav gives a distance of 503 nm(nautical miles) to Moab airport(KCNY). Avgas costs 5.30 dollars per gallon. 1.00nm =1.15miles.
