Hi all!

 

I fly the PMDG 737 NGX with Fs2Crew.

 

My problem with this is that the Recall Button is Lighiting about 30nm (Nautical Miles) from T/D (Top of descent)

 

What has happened? Its same when im at the ground and im just gonna pushback from the Gate, the recall is showing "Air condition", the Co-Pilot turns it off just before taxi when i have completed the checklist.

 

This repeat in the flight as i said previously is showing "Overhead Air Conditon" at the gate it was just "Air Condition" now is both Air condition AND Overhead just before T/D

 

Do anyone have a clue what this problem is?

 

Thanks!

Sounds like you're not completing some part of the flows.  The packs are probably off.

Thats what my Co-Pilot should do, since i fly with Fs2Crew!

Get a new co-pilot. And make sure you check your pressurization climbing through 10,000ft.

Okay...then your issue is something I'd bring up in FS2Crew's forum.  Would that not make sense?

I'm guessing you have a "Off Schedule Descent" amber illuminating?  Hit recall and look at AC panel and it is probably illuminated. 

 

This occurs when you begin descent before reaching the cruise altitude set in the pressurization FLT ALT window.  You can cancel this light by setting any altitude lower than your current altitude in FLT ALT.

 

If I remember correctly the pressurization system "cruise" relay trips based on this setting - changing pressurization from a proportional climb schedule to a constant altitude mode - (lowest allowable cablin altitude respecting max differential - which varies slightly at different alitudes )to avoid pressure bumps during cruise flight. 

 

If you start descending before reaching the cruise altitude set in the window, the system assumes you are doing a emergency return, and starts returning the cabin pressure to the takeoff field elevation. 

I am using FS2Crew as well and never had any problems with it. Make sure that you are performing all the essential checklists and flows - your virtual FO should actually set everything up properly, provided you did your job as a captain and performed all of your flows.

Tried to fly to Hamburg from Arlanda and when i reached FL330 i started to descent (Max FL360) and the recall button started to light and on the F/O seat the recall shows ''Air cond''

 

Here are some screenshots i took when this happened

The dashes in the pressure controller display show you have some kind of pressure control fault active. It seems there is no cruise altitude and landing altitude set. Hence "Auto Fail" light is on.

You don't have to hit recall to see the light on the overhead illuminated.

Kyle - Please can you stop seeing your signature as giving you a right to consistently make condescending and patronising posts? It really does lower the overall tone of the forum. Sure it's your choice and i dont have to read them etc..., but I think it is totally unnecessary and undermines your otherwise hugely valuable input to the forums. Just saying.

But i dont Understand because my Co-pilot turns it to my maximum altitude which in my hade were FL360, then the Landin altitude is set to auto.

I don't see anything wrong with Kyle's contribution to this thread. It was to the point, given the information available at the time.

That's part of the problem as your maximum cruise altitude is not necessarily your actual or planned cruising altitude. There is no auto position for landing altitude, unless this is an FS2Crew option.

 

If the dashes are part of FS2Crew operation then I wasn't aware of that and I'm surprised it does it. If FS2Crew allows you to choose "auto" then perhaps you should try setting the cruise altitude to your planned cruise level instead of letting it choose. You are the Captain after all. If it sets FL360 and you never reach that flight level then you will get Off Sched Descent caution when you descend.

 

As Kyle said, the problems may relate to FS2Crew, rather than the NGX itself. Although FS2Crew does a lot of setup for you you should really crosscheck it when it reads the checklists at each flight phase.

So. Exampel. I put in my maximum altitude that i want in the FMC, in this case it Will be FL360. And i put in an Initial altitude on the MCP like 8000, during the climb and after takeoff at about 5000 ft, i choose to climb to FL180 and then FL360.

 

Should i put in the initial altitude up in the roof that my Co-Pilot puts maximum altitude (FL360) and i put initial 8000. Is that the problem? I Should put my initial altitude instead of the FL360?

No.

 

I've never had the problem you're experiencing, and given your questions, I'm not quite sure you understand how things work (which is crucial knowledge), which points to a few things:

1. You haven't completed the tutorials that came with the NGX; which likely means that
2. You haven't completed the tutorial flight that comes with FS2Crew

Both of those are integral to understanding how to fly the aircraft and use FS2Crew.  My guess is that you're not doing something properly in setting the aircraft up, which is confusing FS2Crew.  FS2Crew (and a real co-pilot for that matter) would expect you to behave in a particular way.  While a real crew member could compensate for shortcomings, computers aren't that smart, so you get weird results if you don't behave how it expects you to.

 

Fly the two NGX tutorials to get a better understanding of the aircraft (even detailed with pictures of what you should be seeing at that point), and then fly the FS2Crew tutorial, following the scripts to the letter.

 

I have a strong feeling that will have you sorted out completely.

No.

Ye you right, i have never flown the turorial but i have watched many YouTube videos with proper tutorial flights from real pilots from the PMDG 737 NGX, and i followed the steps Excactly like they do, sometimes the AIR COND warning shows but sometimes not (often it does)

 

Thanks for the help!
