When looking at the waypoints in the flight plan in AS 2012 and the wind conditions for each of the waypoints, what altitude do the wind conditions refer to?Reason I ask is I'm trying to ease the job for the FMC to calculate a good VNAV descent profile by entering a couple of wind conditions for at various flight levels in the DES Forecasts page. Do the waypoints in the AS 2012 flight plan take the actual route into account meaning the waypoints should be pretty close to what I see in the FMC on the LEGS page when it comes to flight levels for each waypoint?

Hello Richard,If you scroll down the lower box on the flightplan page you'll come to an entry: 'Winds aloft by waypoint:'The column header gives the various altitudes and is the data I enter for both CRZ and DES purposes.

Thanks alot Stephen, don't ask me how I missed this...guess I should open my eyes :(

Been there myself mate!Sometimes you can't see the wood for the trees :-)

:( True!

Hello Stephen,Could you please clarify what some of these numbers mean?For instance, the top 2 lines show this:Waypoint 6K 9K 12K .......etc 30K 34K 39K ....I guess these are altitudes but why these particular altitudes when I entered a 30000 ft cruising altitude in the flight plan? Also, further down, the waypoints show something like this:LOWI 081@03(5) 056@07(6) etc.... 018@30(-45) 022@29(-55) etc .....I imagine that 018@30 for instance are the wind direction & speed. But what are the negative or positive numbers following inside the brackets?Thank you,Maurice

Someone correct me if I'm wrong but the top numbers you mention are the altitudes like you guessed and these are fixed letting you choose the one that are closest altitude wise to the waypoint you're interested in and the numbers within () are the temperatures.

Maurice,The top line numbers are as Richard confirmed the wind layers, a total of twelve being generated by ActiveSky. The two rows been referenced against the correspoding waypoint.The temperatures are supplied following the speed/direction in () for each layer. They can be utilized in some add-on FMC's to enter a deviation from the ISA standard for that level allowing better determination of max altitude

Thank you guys. I get it now. I don't know why I never clued in on the numbers inside the brackets being temperatures (duh!) :Hypnotized:Maurice
