>Hm, maybe it points to the TRK in stead of HDG? ???????Course is desired track and so it still should point to 45. Michael J.http://img142.imageshack.us/img142/9320/apollo17vf7.jpg

Martin,Based on the scenario you discribed, did some flights observing the APPR Mode.Observed that the CDI pointer, in TRK mode, is not drawn correctly when there is a X-wind. Or to say it otherwise, the CDI is miss aligned by the amount of crosswind component.This can even better be observed when flying a VOR radial, set via the NAVRAD FMS Page, then select the VOR Mode and TRK on the ND.The CDI and RMI for the station have a difference proportional to the crosswind component.Hope this will be corrected in the FS9 version and the FSX Update.Regards,Harry

Xander,Thanks for your very matter of fact contribution.>Hmmm, I'm an airline pilot and although I fly conventional>gauges, logic tells me that even though Douglas "wants" you to>fly the track mode only in MAP mode, it should not allow>conflicting information to be displayed.Have been an airline pilot too, of which I flew MD11's for 11 years. So I can confirm Douglas does NOT "want" you to fly track mode in MAP mode only. >1.

The TRK / FPA were implemented especially for non-precision>approaches. I can't imagine that a non-precision approach has>to be flown in MAP mode. It does not make sense.Indeed, the primary navigation modes in this case (non-precisionapproaches) are VOR or APPR mode. >The CDI information takes information from the course you>enter.

Guys, thanks for your feedback. We will look at this issue for the next update.

Thanks Michael....knew you would chime in one time or another.Xander

You are correct, I had some wrong assumptions.
