Hi all, I'd like to know the following about the NGX: max zero fuel weight max takeoff weightmax taxi weightmax landing weightrangemax cruise altitudenormal cruise speedmax seating capacity Thanks.

How about reading the manuals?

How about reading the manuals?

Tried browsing through it but I don't know where to look exactly...

Start with FCOMv1 or using Google will lead you to this

I wonder if this should be raised again. But I just purchased the NGX a few months ago after having flown the PMDG NG for years. But in both cases the manuals and the modeled plane seem to disagree. In the NGX FCOM it says the MTOW for the -700 is 133,500 lbs. But the FMC reports MTOW as 153,500 lbs. The FMC more closely matches what is on Boeing's website, 154,500 lbs. My guess is that the FCOM is just out of date but I'd be curious to know why the discrepancy.

Hi Dave, just guess that engine options has a lot to do with it.  My copy of FCOM lists max taxi at 133.5 and MTOGW at 133.0 klbs for -700. Regardless, PMDG didn't make these manuals, they come to PMDG direct from Boeing and is copyright by them. Notice the manual does specify Typical, I'm sure that in the tens of thousands sold that there are a lot of variances.

Planes are just like cars.  Sure, cars have generic weights provided by the manufacturer, but the individual cars weigh differently because of installed options.  If one has a nav system, that system will have a weight that a car without it might only have a portion of with a radio only.  If you have an optional full-size spare, then you'll have that additional weight.  If you have leather versus cloth, that'll change the weight, too.

 

Same goes for the plane.  It's something a lot of simmers somehow miss.  Different options will cause the plane to differ from the "factory" value.

Yes a little more searching in the forums revealed PMDG's answer. Which is they modeled the heaviest MTOW option. I fully realize the different individual airplanes with different options will have different weights. It's just it was such a large difference, 20,000 lbs that it made me wonder.

Here you go, the -700, from Boeing website: (For the entire PDF go to http://www.boeing.com/boeing/commercial/airports/plan_manuals.page )

 

I've been to the Boeing website looking for that info. According to that document it appears that there is a 20,000 lb. difference in MTOW between the non-winglet and winglet version of the 737-700. I'll have to check to see if the FMS in the NGX shows that difference when you load the non-winglet version. My guess is it doesn't. I'll have to try it when I get home.

Dave, I think you may be mis-reading that - it means it COVERs all 3 variants, IE you could order any variant at any MTOW. See how the box extends across all 3 MTOW options - that means that info in that box is valid for all 3 sub-columns. If it was specific to version, each version (-700, 700W -700C) would have their own little box around them. 

 

PMDG models the highest option from Boeing at the time they developed the sim product; if you want to simulate a lower weight, just do so via your flight planning tool.

 

Have a look at the document, it is interesting.

 

Boeing seems to be on a trend of standardization these days, with far less MTOW options to choose from. I believe the 787 has just one option.

These are the PMDG weights I've been using for TopCat and PFPX and match exactly to the FMC (not specific to any one Boeing or airline pub).  'M' regs are mixed and 'S' regs are single class cabins.
