PMDG NGX weights mismatch in PFPX


Recommended Posts

Hi all,

 

Having some fuel wrong predictions using the built in PMDG NGX 737WL profile I wanted to investigate the reason. What I found out is that the weights used in the PFPX built-in PMDG NGX profiles are not matching to what I see on the aircraft cfg. The aircraft .cfg and FMC give the DOW and MTOW. So for example for the NGX 738-winglets I get these confusing numbers (in Kg):

FMC/aircraft.cfg : DOW: 41413 , MTOW: 69626

PFPX profile: DOW: 42991, MTOW: 78900

 

Also, the PFPX profiles give different values for the non-winglet and winglet versions, while the aircraft.cfg and FMC give the same values for both.

 

What we are interested in is simulating the PMDG model in PFPX, so in that respect are the PFPX PMDG NGX profiles wrong?

Same here. I am setting up an aircraft from scratch with all weights and data.

So i have same values in PFPX / TOPCAT and P3D.

 

That lets you plan your flight perfectly and you have everywhere the same weights.

At my PMDG 737 i´ve the followed values from the aircraft.cfg

 

MGW = 79242 Kg

Empty = 41413 Kg

 

Max Values (testet with the CDU inputs)

MGW = 79.2 t = MTW at PMDG

MZFW = 62.7 t

1 Paxe = 0.79 t

 

For the PFPX you must see, that the DOW is required. Real DOW = Empty + Crew & Baggage + Water + Catering. This is for the PMDG difficult to determine, but the iFly 737 differs between Empty 41414 + Crew (6 Member)  408 = DOW 41822 

For PMDG you must take 41413 as PFPX DOW, because i can only complete with Passenger and Cargo in the Airplane, the Crew is missed.

 

At the difference airplanes all weights are often stated incorrectly. In conjunction with Airplane Configurator / TOPCAT / PFPX / Load via CDU very difficult.

Thank you guys..

 

I do the same, just wanted to be sure and report that these profiles on PFPX are not accurate.

 

This is what I measure:
