On a real world flight recently I`d entered all the en route winds into the FMC but hadn`t put the descent forecast winds into the machines VNAV descent page. I remembered I hadn`t done it but I thought I would leave them out as I didn`t think it would make much difference and the aircraft would just use its current sensed wind to work out a top of descent point.I was wrong, the VNAV path was all over the place and almost unusable, I ended up using FLCH for a large part of the descent. Lesson learned there.CheersJon Bunting

Jon I'd be grateful if you would give me guidance about my query dated April 20 in this string. It includes a screen print illustrating a problem I have entering the information manually into the Forecast page of VNAV.Cliff

Hi Cliff,Yes, if you want to enter the winds over a waypoint you need to go to the LEGS page and select RTE DATA bottom right button. Once in there you need to enter your flight level into the left side then your wind on the right side, there is a RTE DATA page available for each waypoint.The page on your screen shot there is the VNAV descent forecast page, on that page you dont enter waypoints but altitudes on the left and winds on the right, so it will end up looking something like this350 240/78300 270/60250 190/45I hope that gives you a clue, perhaps someone else could give you some more in depth expanation, I`m just turning in for the night here in Vegas, I`ll get back to you in the morning if you need more helpcheersJon Bunting

Is the RTE DATA page modelled in PMDG? Mine isn't functional... am I doing something wrong or am I supposed to enter the relevant data once airborn?I use ASE so this kinda data is easy to have the problem is how to use in FS.

Yes it is there.. press the side button next to the RTE DATA prompt. Them manual has examples and instructions.

Hi Jon! This morning I was up at five to see whether you'd answered and was delighted to get your input.I'd appreciate your comments on the screen pics to see if I'm on the right track. They are:LEGS pageACT RTE 1 DATAACT DES FORECASTTo program the FMC I used the information on the Active Sky page bearing eight coloured boxes entitled Wind direction, Wind speed, Visibility, Precipitation, Temp, Pressure. Below each box are (I assume) altitudes ranging from 3K to 49K. And below them are vectors and speeds.Incidentally you note that "there is a RTE DATA page available for each Waypoint" I found only the one page as illustrated on the screen print.How am I doing?Regards.................Cliff

I've noticed that the FORECAST page was missing from my last post. Here it is;Cliff

Each waypoint has RTE DATA fields, the number of pages just depends on number of waypoints.

Cliff,The info shown in the screen print from ASE is only regarding your departure airport (KSFO in this instance). You should go to the "Briefing" page (the buttons at the top) where there are METARs for destination/arrival and alternate and temp/winds info for various altitudes for every point of your flightplan (you must load a flightplan in ASE in order to have this feature- check ASE manual it's an easy procedure).

Hi George...Am I correct in assuming that the winds and vectors at varying altititudes are in the lower section of the Briefing page entitled "En Route Textual Briefing" as illustrated in the attachment with this posting?If so please where can I learn how to interpret this information? e.g In sentences such as AVE:KPRB 221953Z AUTO 00000KT 10SM BKN075 12/07 A2976 RMK AO2 SLP078 T01220072KPRB 221730Z 2218/2318 00000KT P6SM -RA SCT030 SCT045 OVC060 FM222100 05006KT P6SM SCT050 FM230300 VRB03KT P6SM SCT150Cliff

You are correct and check this link for METAR interpretation: METAR information

Grreat! Just what I need Wayne.Thanks.Cliff

You can go here as well and the sight will translate for you. Just press the translate button and check both metar and taf, it will translate both for you.http://aviationweather.gov/adds/metars/METAR text: KORD 230551Z COR 06004KT 10SM FEW100 BKN250 06/02 A2988 RMK AO2 SLP120 T00560022 10106 20056 401560033 53002Conditions at: KORD (CHICAGO O'HARE, IL, US) observed 0551

The aviationweather.gov site is the best weather site on the net. It is put together 24/7 by a small staff in a windowless building in Kansas City. They do a great job.

Hi guys, a simple question...related to PMDG 737 NGX.

 

1) Can i insert winds aloft data only for cruise waypoint?

 

2) Have I to use "descent forecast" page on FMC for inserting three different altitude?

 

3) and for climb phase, no entry?

 

I have fsbuild and in its navlog are reported winds aloft for every wypoints of my route, can't I insert those for climb and descent?

 

Many hanks
