Reported winds, S-Turns, Build 394

[bojote 20]

DWC control is enabled, and, while in cruise (not always, but regularly) the plane is kind of strugling to keep a straight line. This is the Level D 767, I took a snapshot for you to see.Notice that the reported winds (as shown pressing CTRL-Z) match those in the EHSI, however, the FMC is reporting completely wrong winds. This does NOT happen when DWC is disabled... so where is the FMC reading the winds from when DWC is enabled? One more thing I noticed is this:I have my weather updates in ASA set to every 10 minutes. Each time there is a weather update the FMC alternates with good reported winds then reverts back to bad winds in the next update. So, it seems that a weather update fixes it, but them comes another update and it messes up the winds on the FMC. why?My guess, is that the Level D uses the wind data (reported on the FMC) to maintain track. If this wind reading is innacurate then the plane goes off track.

Thanks Jim, I also posted the question to the LevelD forums, it would be interesting to see 'where' does this wind reading comes from.. it could hold the key to the S-Turns/Wind shift problems...

One more thing... the winds the FMC displays are the ORIGIN airport surface winds

An interesting observation...Yesterday, I forgot to load the flight plan in ASA, but noticed in mid-flight... interesting enough, I did NOT experience the problem described in this post, weird. For the first time a 3 hour flight, no s-turns, and the reported winds on the FMC were matching those in the sim.

talked to soon... again, the 'ORIGIN' airport winds are the ones shown in the FMC from time to time.
