STEP 4: APPLY NEW WINDS TO REMAINING LEGS AND UPDATE ETA AND
The next step is to take these "new" winds and apply them to the new course to
Blountstown (057°T) in order to determine a new True Heading and predicted
Ground Speed. The True Heading is calculated to be 055ºT, and the Ground
Speed is calculated to be 131kts.
With the new Ground Speed and remaining distance to Blountstown a new ETE
can be calculated. Given this new ETE and the fuel flow, a new leg fuel is
calculated. With the given fuel on board minus the calculated amount of fuel
used up to this point (22#), a new EFR can be computed at Blountstown, just as
in the preflight steps. In this case, the ETA will be 16+59 (11+54 ETE added to
5+05 elapsed time) with an EFR of 745.5# (815# start - 22# getting off course -
47.5# leg fuel).
Repeat these steps for the remaining legs to derive an ETA and EFR at the
destination. The results are logged in the jetlog as in Figure 4.7-20.
