In my case, the values are wind 312 at 31 knots and a temperature of -
54.2C.
During the initial FMC PERF INIT setup phrase prior to calculating fuel
load, we can make entries based on these values that will cause the FMC
to take them into account and show the effect on our fuel burn.
There is a simplified but less accurate way and a more complicated but
also more accurate way to enter the wind predictions.
The simple way:
Because the 737 generally flies short to medium range routes, it is often
sufficient to just enter the winds aloft average for the whole route.
You do this on the PERF INIT page at LSK 3R. When I put my current
wind average of 312/31 into it, the fuel prediction at LOWI goes from 3.2
to 3.4, which indicates that I’ve got a tailwind component and I’m going to
burn about 200 lbs (90.7 kg) less fuel than I would in a no-wind situation.
Do the simple way first even if you’re planning to do the complex way.
The complex way:
Press the LEGS button, then press LSK 6R to go to the RTE
DATA pages. This is a list of the waypoints in the route and their
corresponding winds aloft predictions.
Press NEXT PAGE twice until page 3/9 is shown.
