hello,i am a little foggy on this,i enter the wind,direction,temp on the ground while programming for a flight but do not enter any more data.i am wondering should i keep updating these numbers and at what intervals.thanks for any help.tony.

There are at least 9 specific FMC units as both payware and freeware. You must provide much more specifics before you can receive any help.

hi,well i mostly use the pmdg and pic 737,and once in a while the pss series.i have read the manuals,but if it says in there i am missing it.thanks,tony.

I usually input most wind data on the ground and maybe finish up on the way to initial cruise. Never touch them again.I think, and I'm reaching here since I'm not a real pilot, that ACARS(to FMS) is how weather data is updated enroute.regards,Markhttp://www.precisionmanuals.com/images/forum/747400.jpgXPHomeSP2/FS9.1/3.2HT/1024mb/X700pro256

i guess i was doing it almost right.thanks for the help.tony.
