INSTRUMENTS FLIGHT PLANNING
FUEL PLAN SECTION
The backside of the jet log has a fuel plan, which is completed during preflight planning in order
to simplify the process of making decisions during the course of the flight. Figure 1-21 depicts a
breakdown of a fuel plan for this flight:
Figure 1-21 Fuel Plan
CLIMB/ROUTE DEST IAF This figure is your total fuel burned from start to arrival at the
IAF. This number is taken directly from the front of the jet log.
ROUTE ALT IAF This figure is the fuel required to go from your destination IAF to your
alternate IAF at cruising altitude. (ALTERNATE PROFILE #1)
APPROACHES For preflight planning, use 40 lbs of fuel for each planned approach.
TOTAL (1, 2, & 3) The sum of lines 1, 2, and 3.
RESERVE 10% OF LINE 4 (Min 20 mins) This is your required reserve fuel. It is either
10% of the sum listed in line 4, or pre-computed reserve fuel (60 lbs for T-34C, 125 lbs for the
T-6A). Choose the higher of the two.
START/TAXI 40 lbs
TOTAL REQUIRED (4, 5, & 6) The sum of lines 4, 5, and 6.
TOTAL ABOARD 815 lbs.
SPARE FUEL (8-7) The difference between lines 8 and 7. This figure is the final determinant
for your "go" or "no go" decision. If you have at least zero spare fuel, you can legally fly your
route under the conditions expected in preflight planning. If your spare fuel is less than ZERO,
your flight, as planned, is not feasible. You should revise your planning using more favorable
