737 NGX 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

There is nothing FSUIPC will do to control how much thrust it takes to move the aircraft. There must be other factors, like loading, wind, ground friction and so on. 26% N1  is 26% N1, 35% is 35%. What then happens is up to the simulation engine and environment.

 

Well is this a FSUIPC problem? 

 

No.

Hi pete hope you had a nice time off !

I'm not sure whats going on because when i first bought FSUIPC i then assigned everything through FSUIPC with my saitek throttle quadrant and thats where the thrust problem started yeh! So what i done is, i then set the saitek thrust lever back through FSX and worked fine like before i assigned it through FSUIPC.

It can't be loading as i fully loaded the AC down and it still moved with minimum thrust pete!

Pulling my hair out now, i have sent a ticket to PMDG and contacted jetmax also.

But the N1% reading from FS, the one shown on your cockpit, IS the thrust. There's no other. It doesn't matter how it gets to that value, whether by keyboard, throttle lever, writing the value directly in the appropriate memory location, that's it. I don't see how any control method can be involved in such a discrepancy -- unless it's the ground friction. Are you using the option in FSUIPC to change rolling ground friction values to what most folks say are "more realistic values". Have a look in the FSUIPC4.LOG file.

 

BTW a real 737NG will definitely start rolling with idle thrust. you have to keep the brakes on to stop it.  Maybe it's just that you aren't used to such realistic behaviour?

I have added that line in FSUIPC.INI and also moved that file to the modules folder? Is that correct?

Why look in the log file? Am i looking for something.

Maybe but i've heard it takes upto 35 for brake away trust at heavy loads. I just need to touch the levers and the thing rushes upto 10 kts lol

Thanks for the help so far.

You enabled the Lua friction file? that will explain differences in rolling resistance, for sure!  You'd need to undo that, and also make sure that "PatchSIM1friction=No" is set in the [General] section of the FSUIPC4.INI file -- else default frictions will be changed automatically too.

There'd be a line saying frictions were patched if "PatchSIM1friction=Yes". But it sounds like you are deliberately patching them using the more sophisticated Lua method anyway -- or even as well?

Well, I think you've heard wrong. If your engines are running you won't have to even touch the levers for it to start rolling. If you are moving them then yes, it'll "rush" instead of gently accelerating. You need to keep the brakes on!

 

However, if you prefer to have the ground friction preventing this, you now now what to do.

Ok so what am i to do here then? Remove the lua text in fsuipc.ini and replace it with this PatchSIM1friction=No?

 

Just undo what you've done, if you want FS's older non-realistic frictions. i.e. delete the friction lua file from the modules folder, remove the line you said you added in the FSUIPC4.INI and make sure that parameter I told you is set to No.

 

Sorry getting a bit lost with the steps to perform the friction!

 

 

This isn't "performing the friction", this is removing a facility in FSUIPC which most folks seemed to want, to give more realistic rolling and side friction on the ground, and which you evidently don't, that's all. It was a facility i put in on request. I did not devise it.
