Howdy folks!I recently bought ASE, and it sure makes a difference in terms of weather depiction among other things. Getting accurate winds aloft data is fantastic and makes my FMS very accurate. I do have one question though. How does one get the most accurate descent forecast values from ASE or other souces? Currently I just type in my destination airport in the reports section of ASE and use the winds aloft data there. The only problem with this is that I am not flying at those altitudes over the airport and I don't think it is the most accurate. Do you captains have any better ways to do this?Thanks!

excelent question

You can load a flight plan into ASE.

For FORECAST ? My preferred method is entering the destination ICAO in the REPORT page of ASE. Then I usually enter 3 altitude values that represent the wind "curve" in "interesting" altitudes where something changes. For starters try FL090 FL180 and FL300. That will cover most stuff.For ISA deviation I usually check the FL180 temperature. ISA is -21 C there. I also secondarily check the FL300 temperature (ISA is -45 degrees at that altitude). Then enter a number corresponding to the "average" ISA deviation between these two.Hope this helps.

i just download my flight plan into ase and than it gives me the wind direction and speed at each way point

Like you I just bought ASE. Really enjoying the much better weather depictions.Save your flight plan in both PMDG and FSX (.xml) format. Once ASE has finished starting up, click on the "Briefing" button, then click on "Change Flight Plan", then "Import" (it will look in your FSX FlightPlans folder for .pln files). Select your current flight plan, and in the window that appears, enter your Alternate Airport and Estimated TAS in knots. Then click "Process." In the Text Briefing you'll see Winds Aloft by Waypoint. From your FMC get your projected altitudes at points along your descent and use the data supplied by ASE to get estimates of, e.g, winds at 30K, 20K, 10K. It will also give you an estimate of average winds at your cruise altitude. Pretty cool.I don't know where you fly mostly, but for flights in the USA the info appears to be very accurate.

I use FS Build + ASE and then manually put it into the FMC....like a RW pilot would :D

I use fltplan.com to get my winds aloft. it even gives you a general FMS speed average to use on the perf init page as well as an awesome navlog for the entire route. great place to get current canadian plates also.

Hi,For those who are flying in Europe and who wants to fly very seriously here's the "Aviation Weather in Europe" link to acces to:Significant weather charts for 00 - 06 - 12 - 18 hr. UTC, Winds Aloft and Temperature Charts, Notams and so onhttp://www.flyingine...eather_maps.htmThis is freeware and update every day, here's a few pictures...Have nice flights guy'sNile Daniel

I use FSBuild+ASE like you. I obtain a navlog from FSBuild with wind direction and speed for every waypoint of my route. But the question is: how can you put those value for every waypoint into FMC? For example, in 737 NGX you can only put those value for cruise phase and descent forecast, not for climb. FSBuild navlog gives you also "climb" waypoints with respective winds and speed. How do you do in this case?

i was hoping someone will bring that up, i have a question about that, how do real pilot's planning their flight? do they have a program like active sky which tells them the wind aloft? thanks cheers.

No, they don't have ASE, have winds and temp aloft provided via data-link, not implemented in NGX.

 

However you HAVE to set winds aloft for cruise waypoints only, and in DES FORECAST for your descent phase of flight only. For climb you have to assum TOC winds aloft data.

i didn't mean to the spacific program, i said like, and for the rest, i think i will have to take another look at active sky as i have never used it for that matter, i don't really know where i can get this kind of information, so thanks for bringing that up, cheers.

I use something similar to Daniel. It is worldwide but not as accurate. Its page is: http://www.aviationweather.gov/iffdp/. This of course only works if you are using real world weather but it has been very accurate for me.

You can put a checkmark on the briefing side that says "Show Surface Information for Dep. Dest. and Alt (vs. Aloft)"

 

Then ASE will show you weather information for the ground on both Departure and Destination airports instead of the aloft data. But you do have to load a flightplan for this to work.
