Ryan (PMDG) Help (FIX) required please Re. attitude on finals

Featured Replies

Zach..not here to debate with you as I said in my first post so why bother posting unless you like to be popular in which case start your own thread and for your information, you were not trying to help anyway. Already Ryan has said they used the Unreliable airspeed tables for attitudes for the NGX which is already incorrect since its not meant to be used for normal flight at Vref + 5. That Vref+10 is a safety buffer put in to make sure the aircraft will not be too slow on approach. AS CONFIRMED BY RYAN :
That's fine and dandy. You missed the point of my post, where I quoted a very specific thing you said, and added my ".02" (as you put it). Never did I ever say that your issue had no merit. Rather I addressed your blanket statement (you know? The one I quoted in my post). Rather or not my post was useless .02 or not, you mentioned me "having no sense in flying".... By all means, talk to folks anyway you please behind your monitor.
My research has led me to further conclude that simming in the nude with the PMDG 737 affects neither the approach or landing atttitude(s); however, it DOES have the effect of making me feel INCREDIBLY SEXY. Please don't judge me.
Funny!
Nice find. Thanks to Tony

Hey Rick, go ahead and post the flap settings I gave you for both versions of the -800.. I'm working on the 900 now.. You can always save your original settings and revert back, although I think you guys will like the realism.. Enjoy mates..

@OP Sir,1) Please sign your posts per PMDG request.2) Your statement about the landing attitude might be right but being arrogant and agressive isn't necessary on this forum.

Ryan or anyone from PMDG. Is it possible to advise how to change the attitude from approach all the way down to landing by 2 degrees for all flaps setting from the default one you guys have programmed into the 737NGX. That way some of us real world pilots can use the attitude we feel is right and replicates what we see in the real aircraft while others can continue with the default one without any issues. Brought this up because just had a proper go with the NGX and everything works perfectly except the attitudes on finals are 2 degrees off. I know you were going to look into this from some of the previous post but since this might take time, am sure your programmers could throw out some numbers for me to change on .cfg page or something. Sorry to sound arrogant but those of you who disagree with me saying that the attitude PMDG programmed is incorrect, I am not writing this to be told PMDG got it correct etc etc and that I am wrong. Am over that part and didnt write this to debate over the correct attitudes. Just want an answer from PMDG or anyone who knows how to increase approach attitude settings on the PFD by 2 degrees. Thanks
I have until now suppressed my own suspicions about this because they are based just on a session in a BA flight simulator which was for a -400 not a -800 and I assume based on its marketing and reputation that PMDG would not make such an elemental mistake in such a critical phase of flight. However, we have now heard from some real 737 pilots that the landing attitude is wrong. We have not, I think, heard from any saying that it's right. So: Are there any real 737 pilots who (a) think it's right and ( b ) are willing to come onto the forum to explain why? If not, then I am sorry but IMHO this is a non-trivial part of the simulation which PMDG needs to account for convincingly and if necessary put right, quickly. Tim

Just my pennyworth... All typed posts in any forum suffer from the mis-interpretaion of attitude syndrome . What one person types as a simple comment/request is often mis-read as an arrogant or know it all comment where nothing of the sort is meant. We all need to be more tolerant of different approaches to the written word and this will encourage participation not discourage it ! cheers Brian H

Tim, I am not B737-800 type rated but I too believe that the landing attitude could be tweaked slightly.I wonldn't say that it's "wrong" though.I agree with the OP that for a perfect touchdown at around 4 degrees in calm conditions after a flap 30 approach there is a little something to add to the NGX landing curve.Flare might be improved as well but again, these are fine tuning and not wrong algorithms.

David I'm interested to hear that this is also your impression. I imagine at most it's a matter of fiddling with a few numbers - albeit important ones - the question for idiots like me is not so much "which numbers?" as "please can PMDG do it for me?"All the best, Tim

As much as I love the NGX, I had a feeling ever since I started flying her that the landings seemed a little anticlimatic. I can't really describe it perfectly, but I can attribute it to the following behaviors - at 20 feet, she seems way too floaty, even if I feel like I've done all I could to be positioned for a great landing, like smoothly retarding throttle and raising the nose up 2-3 degrees. As a result of this float, I have to pitch down pretty significantly just to get out of the ground effect, I'm lucky if I can even manage 1 or 2 degrees up when the mains touchdown. - reverse thrust takes forever to engage. Yes, I know about the modeling of flight, approach, and ground idle. Maybe it's just a FSX limitation, and PMDG was right to model this idle behavior accordingly, but I find it hard to accept having to wait 5 or more seconds after touchdown to engage reverse. I'm hoping PMDG will take the necessary steps to address these shortcomings, as landings always seemed like they are more difficult than they should be.

Why do people who come up with legitimate criticism about the NGX become the victim of abuse here? I think the OP has a point, which you can see for yourself in the sim. It's not arrogant or uneducated, quite the opposite.

The aircraft flies 10kts faster than it should on approach - reason being is PMDG used the unreliable airspeed tables which is Vref + 10 attitudes and thrust settings. For every 5 kts above Vref, lower nose by 1 degree, and thats why we see 0 (Vref + 5 + 10 unreliable airspeed table additive which causes the further 2 degree pitch down) on the PFD instead of 2 degrees (Actual Vref + 5). More simply put, you think you are flying an approach at Vref + 5 but in actual fact, you are flying it at (Vref + 10) + 5. Thats the reason for the lower nose attitude on touchdown (2 - 2.5 deg instead of 4 to 5 deg) and the reason for the float because the a/c is 10kts faster than what you should be on the flare. Anyway, thats my 2 cents worth. Didnt mean to sound arrogant as i put it in the first post. Obviously this site isnt really meant for real world pilots. Thanks all those who tried to help. Happy landings!

I suspect some people just bring it on themselves...
... some of us real world pilots can use the attitude we feel is right ...... I am not writing this to be told PMDG got it correct etc etc and that I am wrong...
... dont think will really waste my time with someone who hasnt flown jets for real...
...not here to debate with you......Anyway, bet guys like you will sit in a real 737NG and tell the pilot the landing attitude......Isnt there any real B737NG pilots in this forum???...
This guy has a problem with his attitude, but he believes it is someone elses problem.

Paul Smith.

Braytoncycle real world pilots are welcome here I am one just not a jet pilot, you sir are very welcome here just dont play the real pilot card with attitude can be a sore point for all us poor souls that fly around in windmills he he
