Here is some data from an actual flight plan for an S-80 via American Airlines. The data reads horizontally, but I will have to list it vertically here. The route leaves Chicago for Puerto Vallarta Mexico. There are actually about 18 waypoints but I will list only the first line:
TO        BAYLI
IDENT   BAYLI
FL 32
LAT      N394265
WIND   29096
LONG  W091047
WCP   M036
MC    230
MH    241 
MK    760
TRR   009
GS     409
TAS   445
TD    P00
I       0
SD    0103
TLDR 1461
ST     0017
TTLT  0017
SB    0051
TTLB 0051
IDENT=identifier (would be 3 leters for a VOR/DME)
FL= cruise altitude
LAT= latitude
LONG=longitude
WCP= wind component (M=minus/headwind, P=plus/tailwind)
MC=magnetic course
MH=magnetic heading
MK=Mach #
GS=ground speed (TAS+/-WCP)
TAS=total air speed
TD=temperature deviation from standard
SD=segment distance
TLDR=distance remaining
ST=segment time
TTLT=total time
SB=segment burn
TTLB=total burn
Questions:
What does WIND 29096 refer to? Wind from 290.96 degrees NW?  Or wind from 290 degrees Northwest at 96 knots?
What does TRR refer to?  I cannot imagine what this value stands for.
I do not know what 'I' refers to either.
That actual flight plan contains much more data, including:
aircraft weights
passenger loads
runway choices
CI or "cost index"
alternate route for 1 engine out condition
Dispatcher/Captain/First Officer listed
Flap speed settings
Weather conditions
I hope this has been of interest to some of you, as I myself found it quite illuminating.
Yes, the wind is from 290 degrees (i think magnetic) at 96 knots.
I'm not sure about TRR.  Looks like it is some sort of direction.
"I" might stand for icing? But I really don't know.
I agree with you. Using a fraction of a degree for windspeed would be getting just a tad precise, I would think. Noteworthy is that wind directions are posted as 'from' while aircraft headings use the direction 'toward' convention. A bit confusing unless one is accustomed to the standards. It does make sense that a wind from 290 acting on a plane heading at 230 would generate a headwind component of about 30 kts if the wind speed were around 90 kts. I'll need to review my trigonometry!
What is really interesting is that the wind values can be different for each leg of the route. The wind component changes each time the aircraft changes heading. I believe that it is only possible to choose one wind direction with FS-2002 which is what I still use. Makes things much simpler, though not as realistic.
