Hi. I've heard that PMDG built the NGX with Boeing's blueprints; however, this does not preclude PMDG from making mistakes (anyone who's watched the Nick's 737NGX Walk-Around video on flyaoamedia.com would be aware of this).I've attached a picture that shows a possible error with the NGX wingbox (indicated by green lines) where the position of the NGX ram-air intake is well forward of the ram-air-intake position on the actual 737 NG (compare the ram-air-intake position relative to the Krueger flap). I've also included a comparison of an actual 737 NG wingbox with that of the NGX wingbox to show the differences in wingbox shape (the NGX wingbox is more "rectangular" in appearance whereas the actual 737 NG wingbox has more of a "curvy" appearance).This is not a flame thread or an argument thread; this is a discussion thread. If people think that I am wrong, then please provide evidence to support your statements. If people think that I am right, then I hope that PMDG would consider looking over the blueprints again in order to revise the entire NGX wingbox with future updates of the NGX.Thank you.

Discussion: I disagree. Proof: The same pictures you provided.

That's a start. :( I still think that the ram-air-intake positions are not the same. I also still think that the wingbox shapes are not the same (this statement is tricky because the shape changes depending on how the wingbox is presented).

It could have changed over time or been specified in a customer request. It wouldn't be the first time Boeing has made design changes.Ref: that ridge above the cdu's tht isn't present in the ngx. It doesn't mean the ngx is wrong, only that it doesn't match every 737ng produced.

This is a very good point. It does, however, appear as though that the ridge still exists on the NGX, it's just that the NGX CDU (along with the lower EICAS display) is located further up so that it covers the ridge, perhaps.

Right, but that was an actual change in the design. Some have the prominent ridge & some look just like the ngx, which according to pmdg looks just like the cockpit they used to model the vc (with a little extra cleaning)

Ah, I see. Would you happen to know the registration number of aircraft that PMDG used?

The airline who owns it isn't even known to us plebeians!

Ah, wow.

They probably have their reasons, I would imagine some sort of agreement with the airline (else lawyers would have to get involved).All we really know (to my knowledge) is it was well used, US based & a 738.

Is the wing box and or fairing the same for all models from the 600 to the 900? Maybe the different fuselage lengths effect the aerodynamics and therefore each model may have different belly fairings. Just a thought

The wingboxes for all of the NG variants appear to be the same. The wings for all of the NG variants have same span (112 feet, 7 inches without winglets and 117 feet, 5 inches with winglets).

I love perfection as much as the next guy. But sometimes there's those things that you just have to "let slide", not read to much into, and not make a big deal about (not that you are). this is one of those times.mitch bowman

I understand your point, but I disagree that this would be one of those times because PMDG is currently making updates to the aircraft (SP1c being the latest, proposed update), so I don't think that it would be asking much for a fixed wingbox (unless, of course, there is no error to be fixed). :(

Sorry, I cannot help you as in other topics I was attacked because I'm giving info... so, because this topic is already considered useless (but I think you are right asking when the product is still updated) I will not post drawings about it.
