737 NGX N1 movement with throttles

Recommended Posts

I have the 737 NGX and the jetmax TQ737 throttle. But something is off because when i load down my plane MAX out, it only takes 26 % N1 to move the AC and thats aload of bull because before i used FSUIPC it took around 35 or even more to move it. Now imagine if i was carrying alot lighter load, the thing would take off with a slight touch of the throttles!

 

Any ideas or help? I did try send the controls to FSX but i can't synce the full range of motion on both throttles, it seems the NGX is out of sync or FSX is and doesn't match my TQ throttle adjustments.

Below is a link to two pictures. 1 is when my throttles on my TQ737 is at idle and you can see in the ngx it doesn't return to idle


 


second picture is full thrust and again doesn't go to full thrust in ngx. 


 


any help anyone??????????????? these are set through FSX different from my first post. so either way i can't use FSUIPC OR FSX WITH MY TQ

The throttles in the sim are not in idle or full position.
So i'd say it has something to do with the calibration of your TQ

Yeh but only way i can fix the axis is through FSUIPC but i can't use FSUIPC because somehow the NGX moves at 24 N1 when its fully loaded.

 

I honestly give up

 

At the moment i'm not enjoying FSUIPC because now all my controls and buttons have somehow mixed up! The controls on my TQ i assigned have somehow switched over to my yoke

 

WHAT IS GOING ON

Do you have the fsuipc lua ground friction script installed?

 

This actually makes the breakaway thrust more realistic by fixing the messed up fsx ground friction.

Not i haven't got that?

 

All my FSUIPC assignments have just messed man

 

I just want to fly man. Why has FSUIPC MESSED things up

Installed the friction and the NGX still moves at 24 N1 under full load

 

Anyone?

Infact it moves at 22 N1

 

Need serious help

Yeh followed it to the letter.

 

Even my old saitek lever moves the AC at 22 N1 when fully loaded. Something is wrong

Maybe try it with the iFly 737, which generally is easier to configure/intregate than PMDG with add-on hardware, as they release the SDK to developers. It's a risk free gamble, as Flight1 do a 30 day money back guarantee. If it works with iFly, at least it means the hardware is OK, if it doesn't work properly with iFly either, maybe it might might point to the hardware, or be PC related, but either way progress will have been made?

Just a thought,

Eugene

PS Also once you've registered your iFly version, you'll have access to the iFly forum, including the Cockpit Builders forum, which has some really knowledgeable folk in residence. But pay careful attention to the install instruction, iFly's anti piracy measures are quite tough, UAC and anti-virus etc need to be disable. Also Win8 is not supported, although there are unofficial work-arounds that some have used successfully.

Thats a good thought thanks! I may try that out.

 

I'm not sure why this is doing this. I have even tried it without running the FDS GLARE, still the same problem.

 

Even my saitek lever through fsx behaves the same.

 

Maybe reinstall the NGX and FSUIPC?

Im not sure what your issue is?

 

Most jet aircraft will move on the taxiway with minimum thrust. Breakaway thrust values in FSX have always been useless, hence the need for FSUIPC LUA fix.


A quick look on the web shows 737 NG's can quite happily start moving at min thrust. Max thrust in any situation should be 30-35% for taxi purposes.

 

Perhaps Im not understanding the problem correctly. Apologies if not.

If i set my controls only to FSUIPC and fully load the NGX it moves at 22 % N1 and rapidly builds speed to 10 kts! This isn't normal for a full loaded AC. This isn't right i can't even taxi without constantly braking.

 

I installed LUA and that seems like its not working. I added that line in FSUIPC.INI and copyed that file into the modules folder.

In the immortal words of David Gunson

 

 

Just noticed that - Brings back memories - we were both controllers at Birmingham (EGBB) in the seventies - he's a funny guy ( everyone called him "Bunny Gunson" for some reason) - those were good days....

Minimum thrust yeh but its fully loaded it shouldn't take 22 N1 to move the AC and it then rapidly builds up speed?

Blast from the past ;)

I just tested my iFly 737-800, At around 60 Tonnes (so well below max}, and an idle of 20.2%, it would stay put if the brakes were released, and from around 20kts taxi speed, it would take about 1500M to come to a stop. I use the same throttles in a JetMax supplied by FDS.

I normally go to about 35% just to get it going, then around 15kts back to idle, after 20 secs or so, it slowly de-accelerates, so I put a bit of power back, then idle again, and continue like that. I rarely need the brakes unless I've mis-judged a bend, or need to stop completely.

As an experiment, I tried 24% from a parked position, and had the same result as you, it continued to accelerate, and by half way down the runway was doing 30kts, but back to idle, it stopped in about 1200m with no brakes. It seems that extra 2% is the critical factor. As your other throttles give the same result, it indicates that the PMDG model is the problem? Maybe try the iFly even if you don't intend to keep it?

Thanks so its not just me thats going crazy haha! I need to take it to about 24 % N1 to get it going.

 

How is the IFLY 737 ?

For me with a JetMax, it's a no brainer - they produced a cockpit builders edition designed from the floor up for that sort of project. It makes the whole process of launching the sim a one button procedure. I've got both, and I think in the cockpit eye-candy department, the PMDG has the edge, but technically the iFly is nigh on perfect, and works well with 3rd party hardware. Before the JetMax, I used it with VRinsights CDU, and 737 Overhead, both of which wouldn't work well with PMDG (at the time at least.),

But both are fine products.

Both very good products! Even though i haven't tried the ifly.

 

Thanks for checking out the taxi thrust for me. Surely at heavy weight the NG would take alot more thrust?

I was just watching a Frogglesim video about using FSUIPC, in it he said PMDG aircraft shouldn't use FSUIPC for throttle setting, but use the inbuilt FSX axes controls to set the PMDG throttles - have you tried that?

 

Video here: about 70 secs into video:

I tried setting it through fsx but when i do its somehow using the reversers instead?
