Its not a matter of if its a known problem or not. I didn't post this to just report a problem to potentially be fixed. I posted this because I have this problem and I would like more information to determine if im doing something wrong or not and to resolve the issue. Basically I am just looking for some kind of troubleshooting support. However I am not receiving anything at all.This has happened to me 3 times on all 3 flights i have done with this bird so far so something is obviously screwed up somewhere. Whether it is my installation, my configuration, my setup, or the product itself is undetermined and I would like some help figuring this out. I am not here to complain, just asking for some basic support as a paying customer.Next time make a constructive post and suggest some ideas i could try to help me solve my problem. Thanks!

Chris,Its not a known issue and its not that anybody has decided to not answer you. Chances are as you guessed is that it slipped past us all.You list a number of variables so lets start with the basics.* Is this the preview or the full download?* If its the full download had you fully removed the preview?* Operating System?If you can write what it was you did in setting up your aircraft (from launching FS) or if you wish catch me on VATSIM either as a supervisor VATOCE2 or as a pilot KNT544

Thanks Norman.This is the full download (from the Multi Base Pack).I removed the preview from the add/remove programs dialog then installed the full release pack. I am on Win XP Media Center 2005.My steps are as follows:Start FS2004 (including starting Squawkbox 3 module).Start ASV5 Enhanced.Go to create flight and choose the PSS 777-200LR United livery (used the user edit since the liveries were not available yet). Select my departure airport, in this case RJAA (Using the JapanScenery version of Narita). Leave everything else alone as my default settings. (I am not sure if i have the default FS flight as my default anymore - will check that tonight when i get home from work)Fs loads up in cold and dark as i have set in the PSS setup box.I first turn on the battery. I then request the 2 external power connections and the ground air. Turn on the appropriate lights once power is established. Turn on the ADIRU. Program the CDU. Turn on the weather radar. Start going through the checklists. Load fuel. Recheck the CDU for proper init values based on fuel loaded. Configure the overhead panel (i dont remember the exact steps i took here - I can try this all again tonight and document all my steps. fully). Start APU, disconnect external power and air. Arm LNAV and VNAV. Pushback and start, taxi. All works perfectly until I takeoff and turn on the Autopilot. VNAV then goes haywire. The CDU Legs page shows altitude crossings perfectly fine for the beginning stages of the flight so i would expect that VNAV would climb appropriately. At around 3000 ft, it just takes a steep dive to the ground at like -7000fpm.After i recover and climb I can no longer engage VNAV as it always remains armed, even when i reach cruise. It does however engage again when i dial in a step climb by setting a new altitude on the autopilot and pushing the alt select button.If you need more info, please do let me know. Thanks!

Chris,A full report - thanks.>Start FS2004 (including starting Squawkbox 3 module).>Start ASV5 Enhanced.>Go to create flight and choose the PSS 777-200LR United liveryThere lies your problem.* Choose the ORIGINAL default flight (note that this isnt the same as choosing a cessna at Meigs / Seattle). (Set 122.80 in Com1 whilst you are there)* Maybe you have a favourite gate / field. Go there.* Change to the 777. * Set the XPDR and anything else you want to off* Save flight (set to default if you wish)Now you have a flight that is based on the default flight meaning you dont have to do this every time.You should find all your issues are now a thing of the past.

Ok i tried this in multiple variations and none of them solved my problem.I first did exactly as you said. I saved the flight as my default flight. I then closed FS and restarted it. I then setup a flight the way i normally would but this time the PSS777 was already selected as the default aircraft. No luck upon taking off.Second time I did this all over again, this time though i didnt restart FS. After saving the default flight, i then went straight to RJAA and tried the flight again. This time i did notice a difference though... The fuel calculations were different when it was the same plane and same amount of fuel. It gave me a higher gross weight, higher takeoff speeds and a much larger EFB for my arrival at KJFK. So I thought ahhh it might be working now... Thought wrong. Same thing on takeoff.Funny thing is, my Flight Director is commanding a climb at over 10 degrees. The autopilot just wont follow it with VNAV engaged. It just slowly pushes the plane into a dive. When i paused it before crashing into the ground my fpm was -12500! I was completely vertical nose down.Any other suggestions? I am going to reinstall the package now to see if that helps any.

Norm,When I tried to do this the little PSS panel that is above the windscreen that allows one to click and select various guages disappears reliably when I select the saved flight.GReg

I did a reinstall completely clean. I repeated all the steps with the default flight and all. The same problem occurs.

Chris,Can you please post step by step description of how you program the route and the FMC, also please include the flight plan. It will make replicating your problem easier.Thanks

Chris,When you look at the LEGS page first time after loading the route, can you remove altitude restrictions for ( 635) and D050E and give it a shot.EDIT: remove only the first one Adam

Ok after trying that VNAV just didn't engage at all. It remained in TO/GA mode for vertical navigation although LNAV engaged fine. However the plane magically followed the flight director as if it was in VNAV when i let go of the yoke. The speed was not increasing to 250 though. It hovered around 190-200 kts. Around 9000 ft, V/S mode just kicked in out of nowhere set to 2500 fpm. VNAV disappeared. I clicked VNAV again and it remained armed with V/S mode still engaged. The speed then slowly dropped and I stalled.

I tried it twice, first time removing the first restriction, second time removing both restrictions. Same thing as reported in my previous post. Any more suggestions?

I think some forget the amount of work that goes into making these addons, its a small price tag to pay for something so complex, I dont have the tripple 7 yet but will, alot of these problems are caused by incorrect programming of the CDU, this is something i have first hand experience of with the airbus series, i thought i could program the FMC 100% fault free on my own and still had issues, then i used the tutorials, hense forth the problems stopped. I would suggest try programming the CDU with one of the tutorial flights and if its still is a problem then im sure PSS will do their upmost best to find a solution.So read the manual, follow it by the numbers and see how it goes.//Jabbaru

Just out of curiosity, does this happen at every airport or only at RJAA with the addon scenery ?

Chris,I've been trying to contact you on Yahoo Msg to go over some solutions. Anyway, remove all the SID waypoints up to GUPPI and also remove the altitude restriction of 10,000 feet at GUPPI. This should help isolate the problem.Adam

Next flight... RJAA to KJFK. I was good all the way to the takeoff, everything set right, checklists complete, rotate and climb. All fine. LNAV and VNAV armed and FD stating TO/GA mode in both vertical and horizontal nav modes. At 400 ft, I turn on the autopilot and LNAV engages. Shortly after VNAV engages. Supposedly im supposed to be following the CHOSHI departure off of 34L. My LNAV does fine, but VNAV suddenly commands my plane to dive right into the ground! I disconnect the autopilot and climb quickly. I choose FLCH mode and continue climbing after regaining control of the aircraft. Then the plane just wont climb over 10000 ft! I decide to return to the airport and spend 30 minutes dumping fuel (which is a wonderful feature btw) and land perfectly at the MLW. I re-select the aircraft (since there seems to be no way to reset the plane for a turnaround - AUTOPILOT DISC in red on the EICAS, G/A mode shown etc.) It was a painful flight but i had to try again. Thought to myself i must be doing something wrong. So i try again, everything perfect. I takeoff and BOOM it happens ALL OVER AGAIN! This time i dont give up as the plane this time decides it can climb over 10000 ft. However i could not re-engage VNAV so i climbed to cruise using FLCH mode with VNAV armed. I am currently flying at FL330 in cruise with ALT HOLD mode on and VNAV STILL ARMED. Any ideas on what is going wrong here? I had 75% fuel loaded and im flying the 772LR. I have yet to have a perfect flight. Something major is constantly going wrong...

True, i have not tried this at another airport or with the default scenery at RJAA. I will try both of the latest suggestions tonight.Thanks guys!Chris

Just to update, Adam and I did extensive testing of this problem last night and we found that this is only happening in the Tokyo area. It happened at RJAA and RJTT. However upon trying out RKSI in South Korea, it worked like a charm!We also did some further testing and found some other issues that are happening to the plane around the Tokyo area. Adam has filed a report with PSS and hopefully a resolution to this can be found.Thanks Adam for all your help!
