Has anyone ever seen or for that matter used the following technique for verifying adaquate fuel FAR Part 121 or similar flight plan?
Using the FIX page and average wind to provide preliminary wind calculation for FMC (may not be needed if you’re getting an ACARS wind uplink).
o
Load destination into FIX page
o
Note bearing from destination
o
Insert flight plan average wind at TOD point in FMC, using bearing or opposite of bearing as direction (depending on avg headwind or tailwind on FP)
o
TOD wind propagates back through FP; provides first-order check of FP fuel
o
Update with exact point winds as enroute time permits
