Ok notice how this problem appears when for some reason the cabin pressure starts to drop dramatically, and that is when the autopilot unresponsiveness occurs.then, like I mentioned before after pausing the simulation it recovers,and after almost exactly one hour the issue reappears.

Hello !! Have you guys found any solution for this problem? I did a clean reinstall of FSX, no add-ons at all, only the T7 and the NGX 737 and this issue still persists. Thanks

Hi: Have you found any solution for this issue? It also happens to me on the T7 and the ngx as well.

i have the same issue. Do you get the cabin altitude and landing altitude EICAS message when this happens? In my case, when this occurs, I pause the simulation for a few seconds and the the A/P recovers but then exactly after one hour the problem reappears.

Try with the NGX 737 if you have it and see if the same situation occurs. It happened to me. I'm guessing it's some sort of cabin pressure config problem, I dont know. When this happens I pause the simulation and then the auto pilot magically recovers, but only for exactly one hour and then it goes crazy again.

Curiosly Hi !! Curiously the same issue is happening with my NGX 737. Don't know why.

Hi folks !! Wonder if anyone has had a similar issue. I haven't been able to complete any long haul flights because I get this Cabin altitude alert. At the same time this happens, the A/P seems to ignore VNAV and LNAV for it starts either climbing or descending and also it deviates from the planned route path. I have actually timed the occurrence of this problem and it happens every one hour during the flight(mostly during cruise, although it has happened during any phase of flight) Now, the curious thing is that the problem stops by pausing the simulation for a few seconds and then the A/P regains control, but then after exactly an hour the problem reappears again. Packs are on and cabin pressurization is on Auto but still I don't know what could be causing this issue. Thanks

Greetings ladies and gents !! Hopefully you guys can shed some light on this issue. Few minutes after reaching cruising altitude and leveling off without any problems my bird goes crazy. It seems to ignore LNAV and VNAV because it starts to climb out of the selected flight level at which point I get the Altitude Alert EICAS message and it also deviates from its lateral path. I have done all my weight and balance and fuel calculations correctly, also turbulence effects are disabled. I don't know if its because of REX or the wind speeds aloft and its direction. I have noticed as well that usually it does not complies with the selected MACH speed for cruise(it usually stays at MACH .80 when it should be .83 or .84 as shown on the FMC) at this point if I try to intervene with A/P engaged with HDG select to get back on track, and it banks sharply over 30 degrees and stalls(BANK angle selector is in AUTO) or if I try to correct the altitude it's either no response or it climbs or descents abruptly. Any suggestions...ideas or tips greatly appreciated.!! Thanks

PROBLEM SOLVED !! It was such a silly issue: The date and time in my BIOS was incorrect (I recently did an upgrade) and therefore the activation code was not allowed to get confirmed due to the discrepancy of the date of purchase and the date showing in my system. LOL !!! I wanted to kill myself after spending so much time racking my brains and doing several re-installs of FSX

yeah. It happens to me. I type the activation code, submit it and shows "activation successful" but then if I change aircraft and then select the 777 back I get the activation code prompt again

I have the exact same issues, however I do get my turbofans. Do you also get the activation code prompt everytime you select the aircraft to fly?

Ok folks, here's what has kept me awake for 2 days in a row. :Hypnotized: First let me start by saying that this is not a pirate copy of he product. Any help will be grately appreciated. 1.- Everytime I select the aircraft I get the activation code prompt but then after the activation is succesful I get it again and again. Also I've noticed that once the aircraft is loaded is not doing the system start-up sequence like it does on the 737. 2.- When the aircraft loads it does so with the landing gear retracted (it literally hovers) 3.- All panels are dark and all switches are unresponsive, including the landing gear lever of course which appears in the UP position and may I add that sometimes the engines are running. Thanks

Wow that was fast !! Thanks a lot BA757 !! Found them. !!

Hey guys !! i just need some clarification with one thing. I've recently purchased the PMDG 737ngx package for $69.99 which includes (according to what it is posted on the included features ) some documentation such as the Flight Crew Operating Manuals Vol. 1 & 2, the Flight Crew Training Manual and the Quick Reference Handbook. However, this was not included in the download file. Anyone else had the same issue?? Thanks !!
