ComSimPilot 77 Posted February 9, 2017 Share Posted February 9, 2017 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? Link to comment Share on other sites More sharing options...

srcooke 421 Posted February 10, 2017 Share Posted February 10, 2017 Personally I don't use the template preferring to setup an aircraft from the profile myself. Link to comment Share on other sites More sharing options...
vallewipp 4 Posted February 10, 2017 Share Posted February 10, 2017 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. Link to comment Share on other sites More sharing options...
FraPre 89 Posted February 10, 2017 Share Posted February 10, 2017 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.

ComSimPilot 77 Posted February 10, 2017 Author Share Posted February 10, 2017 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: ===================== PMDG B737-600 ===================== DOW: 36378 MZFW: 50893 MTOW: 65317 MRW: 65717 MLW: 58480 Cargo Capacity:5080 Fuel Capacity: 20891 Max PAX: 119 ===================== PMDG B737-700/W ===================== DOW: 37648 MZFW: 53841 MTOW: 69626 MRW: 69853 MLW: 58480 Cargo Capacity:5397 Fuel Capacity: 20891 Max PAX: 136 ===================== PMDG B737-800/W ===================== DOW: 41413 MZFW: 61733 MTOW: 79242 MRW: 79560 MLW: 66360 Cargo Capacity: 7439 Fuel Capacity: 20891 Max PAX: 162 ===================== PMDG B737-900/W ===================== DOW: 42909 MZFW: 61733 MTOW: 79242 MRW: 79642 MLW:66360 Cargo Capacity: 5034 Fuel Capacity: 20891 Max PAX: 174 Link to comment Share on other sites More sharing options...
