At about 5000f the controlller gave me a decent of to 4000f and then quite quickly to 3000f.

The speed though just kept rising even with the spoilers out all the time.

The 737 is slippery. Even offline, you go down or you slow down, but you can't do both. If you were level at 5k, that was the perfect opertunity to reduce your speed in anticipation of descending.

 

Any NGX-driver who set up ASE 2012 working perfectly smooth with the ngx and wanting to share their setting parameters?

 

Thanx

I thought AS2012 was pretty amazing straight out of the box!

Obvioulsy not other wise he wouldnt be asking

Actually it is. I'm running it quite smoothly without any tweaking. But with the previous version, somebody posted an excellent thread explaining an showing his settings. Using his settings, FSX got a lot smoother and since using ASE2012, it is still smooth, but I lost some performance in comparison to the older version. I'm running everything on a laptop as I'm working abroad.

 

I must admit, it is a little lazy of my part to ask for this. I'm sure I could take the time and tweak around a bit, and find the settings that give met better performances, and, eventually, I will :-)

 

AS2012 settings and fsx.cfg Weather settings. Everything runs great on my rig.

 

Haven't seen this when posting above reply. Thank you for sharing this. Will use your settings and start tweaking from there. You are right that some of your setting are probably to high for my system.

Haven't actually thought of the FSX Weather settings. You use FSUIPC?

 

Thanx again

Sorry Pete, but this isn't REX. It does not have to be 'tuned' to make it work.

Just make sure DWC is enabled (I think it is by default but worth checking) and you should be fine. I do not have or FSUIPC and I do not have problems with unstable weather.

Thanks for your replys, sorry I was busy. And the AS settings thanks.

 

One more suggestion is to make sure your N1 idle speed is correct. If you're on approach and it's stuck around 35-40%, there is a problem.

 

Good point. What is the idle thrust reading meant to say because my N1 is saying 37.6%

Is my throttle stuck. If so why?

Because engine anti-ice is on. Always enter expected altitudes of using anti-ice on descend forecast page.

37.6N1 sounds a bit high for idle N1 at that altitude, even with TAI.

I have compared one video with PMDG and yes, NGX have about 3 or 4% higher idle N1 than real NG.

I have written about that in support ticket, but Ryan told that atmosphere is very complicated thing and such difference is good result for 70$ simulator.

As far as I know FS atmosphere was implemented with some mistakes.

Interesting thing that VNAV compensates this good and I think NGX is quite close to perfection and it's no need to complain more on such small differences.

 

So Matt, if you are flying real 737NG, maybe you have some way to share your ideas with PMDG team.

Sorry Ryan, for opening this topic again.

What I said to you was quite a bit more involved than that, I'd appreciate it if you didn't sit here and make it look like I just blew you off or something. I replied in great detail multiple times to your questions.

 

What I said (in short) was that you would have to know the exact atmospheric conditions at the time the video was taken (pressure, temperature, humidity etc) AND FSX would have to be a perfect reproduction of real-life atmospheric physics in order for this type of comparison to work. The NGX is using the actual Boeing/CFM data for the engines and the guy who programmed it all has a PhD in computational fluid dynamics and does engine performance modelling in real life - if anyone else can do better I would love to see it.

 

FSX (and the NGX) are not perfect - we never claimed they were. What we said is that we've made it as close as is possible given what we have to work with and that remains the case.

It's because you are descending throttles idle because you are way over your speed limit for the decent. Shortly after you took this screenshot, I bet your plane levelled out and slowed you to the magenta bug, then waited for your VNAV to catch up and then continued down.

 

My birds more or less stay on course and path (minus a touch of speed brake) using AS2012 no problem.

Because engine anti-ice is on. Always enter expected altitudes of using anti-ice on descend forecast page.

 

Could you please enlarge on this. I had the anti-ice on pretty much all of the flight. Why would this effect the air speed? Or at least the N1? I'm surprised if a decarded setting can make a engine dangously powerfull on decent.

Also please give a more detailed explaination. I don't understand how that can effect the N1?

An idle engine is an idel engine. Or it isn't.

 

I know I'm over the speed, please don't rub it in :P

I wasn't flying at that stage with VNAV. I was using VS and speed hold (MCPS) , as conservatively as possible.

 

Occationally I do get a mesage in the FMC Something like '10 knots above ISA' or something like that. This was higher up up when I was more inclined to use VNAV.

I replied in great detail multiple times to your questions.

 

Sorry again. I wanted to change my post in the morning.

Ryan wrote me about two pages of text in that conversation with lots of arguments (he always provided great support even with my groundless cavils), I was just too tired to write them all and my English is not so good to write fast. I even thought do I have to write it right then. Always think before you write.

PFD, ND, engine display are filmed there, so I tried to reproduce maximum I could.

Simulator will never be perfect, just because it's simulator.

 

Or at least the N1?

 

Idle N1 will increase.

Hi

The 737's anti ice system uses hot bleed air. This bleed air is normaly supplied by the engines and will heat up the various parts (eg.: leading edge of the wing). In order to produce enough bleedair for the anti ice system the flight idle will rise if you switch anti ice on. It won't make your engine more powerfull, it will just increase your idle trust, but you theoretically loose a little bit of engine power (the same with the packs, if you switch them off, you get a little bit more thrust (short field operations ;) )).

This may be not 100% correct but it is good to understand. :D

 

Hope that helps

You have icing on at +16C. You are attempting to land with almost 9,000lbs of fuel on board. You are 30knots over target and way above the glideslope at less then 5,000 feet while tracking ILS.

 

Go around and set up your approach again, this one is a wash out.

 

Icing is used in certain circumstances for stated reasons and has documented consequences. If you are not quite sure about the details, look them up, but you can summerise it to only required between -10 and +10 below 10k with visible moisture present. It increases idle and reduces available power.

 

Fuel planning is seriously important to the economics and effiency of your flight. Getting it right is very satisfying as it is a way of measuring the quality of your pre flight perperations. It is not that difficult but does take a little care and attention.

 

I can only suggest that you try the tutorials again a few times and watch what the automated systems do, read up on everything that happens that you are not sure when or why it happens, then try to emulate it in manual flight one channel at a time. (i.e turn off VNAV and let it handle the throttles etc.)

Paul,

 

I agree with the gist of what you are saying, but just curious where did the " but you can summerise it to only required between -10 and +10 below 10k with visible moisture present. It increases idle and reduces available power " come from?

 

Certainly not any of the documents supplied or general/generic Anti-Ice usage.

 

Great call on G/A though to our friend.
