The day starts in Mansfield, Ohio by stuffing your Piper Arrow to its max gross weight. The plan is to stop for fuel at Queen City Municipal in Allentown, Pennsylvania on the way to Massachusetts. You load three other people, bags and as much fuel as weight permits25 gallons. Meticulous flight planning shows 1.7 hours to get to KXLL, burning 9.2 gph. This leaves one hour of reserve, slightly buffering the legal minimum 45-minutes of 91.167(a)(3). And, youve diligently followed 91.103 as far as knowing all available information for the flight, including weather, runways and some backup airports should you need to stop en route.
