Planning for a long cross-country flight involves a lot of thinking ahead. There’s weather analysis, route selection, and planning for alternatives. There’s also the need to estimate flight time and fuel burn to meet FAA regulations for minimum onboard fuel. Seems easy right?
The only way to determine the amount of fuel you’ll need, is if you’ve already solved a host of other calculations. To be accurate, you’ll need to know ground distance, forecast winds, and aircraft performance information. You’ll also need to make some choices about altitude and route. Most pilots complete these series of calculations using grid sheets to guide their calculations, with cryptic columns label such as TH, DEV, CH, and ETE. At San Carlos Flight Center, we use a Cross-Country Flight Log sheet that makes it easy to understand the sources of information and the flow of calculations.
In this Ground School Refresher seminar, Flight Instructors Herb Patten and Dan Dyer will walk students through the variety of calculations need for each leg of flight that lead up to the final Fuel Needed number. If you are a new flight student confused about cross-country flight calculations or just need a refresher, please tune in.
