Calculating Fuel

[Chris41]

What I do that works perfectly is using the flight planner for feul estimate. For my 737-800,900, once the flight planner gives me my estimate I had
850 gallons (flight planner estimates are always off around 850 gallons) to that total and then add an addtional 1500 gallons, which is an hours worth
of feul and required with fs passengers. This gives me 47 minutes to an hour and 8 minutes of reserve feul depending on whether or not I have to do a
"go around" or "circle around" due to an aircraft coming in ahead of me that is traveling much slower than I am able to do (atc sometimes lets a much
smaller aircraft land ahead of me,me being second to land, and not putting in enough space or time between us so that if i don't circle around i'll
pass up the other plane on final--hate it when this happens). I do this every time and end up with my required reserve feul load.
PS: the 850 gallons plus 1500 gallons is what works for my 737-800,900. You might have to play around with these numbers depending on with what
aircraft type you fly. Do a test flight or two with fs passengers and look at where you're at in regards to feul in the flight log at the end of the
flight/s.
