14.5.4.1. A multi-leg fuel plan becomes necessary when a mission includes multiple
stops where fuel is unavailable. Use the following procedure for multi-leg fuel planning,
assume a three leg mission with legs labeled 1, 2, and 3:
14.5.4.1.1. Begin with the last leg (3) and fuel plan as normal to obtain required ramp
fuel.
14.5.4.1.2. Next, determine the fuel required for leg 2. Include the required ramp fuel
from leg 3 as identified extra fuel for leg 2. Do not plan for contingency, reserve or
alternate/missed approach fuel for leg 2 unless those totals exceed the required ramp
fuel for leg 3. If this occurs, add the difference in the identified extra block for leg 2.
Use 1,000 lbs. for approach and landing.
14.5.4.1.3. Plan leg 1 using the same procedures you used for leg 2.
14.5.4.2. Fuel requirements must be verified at each stopover airfield. Requirement must
be recomputed whenever the planned burnoff changes; for example, enroute altitude
changes, actual cargo/passenger load differs from the estimate, holding is accomplished,
diversion to alternate is required, etc.
14.5.4.3. Regardless of the number of mission segments involved, fuel planning is
always accomplished by planning the last leg‗s requirements first. The remaining leg
requirements are planned in the reverse order to be flown until the refueling airfield is
reached.
Table 14.1. Fuel Load Components.
1. ENROUTE Fuel for flight time from departure to overhead destination or initial
penetration fix at cruise altitude (including time for planned orbit, escort,
search, recovery, appropriate climb, weather recon, etc. when applicable).
2. RESERVE 45 minutes (2+00 hrs for remote destinations). Reserve fuel will be
computed using consumption rates providing maximum endurance fuel flow
at 10,000 MSL (20,000 MSL for remote destinations). For gross weight, use
end cruise gross weight (ECGW) from section II of the AF Form 4116. If
an alternate is required, compute using weight at alternate destination.
3. CONTINGENCY 15 minutes. Use same fuel flow as reserve fuel above. (Not required for
4. ALTERNATE AND
MISSED
APPROACH
local training missions)
Alternate: Fuel for flight time from overhead destination or initial
penetration fix to alternate, or most distant alternate when two are required.
Compute at terminal fuel flow. Required whenever alternate must be filed.
Missed Approach: 2,200 lbs. Required if destination is below ceiling
minimums but above visibility minimums for planned destination approach.
5. APPROACH/LANDING Approach: 1,000 lbs (2,000 lbs for high altitude approach). Entry always
required.
Minimum Landing Fuel: 4,000 lbs. Entry always required. This accounts
for gauge error. Do not include this 4,000lbs of fuel in the reserve and
