Hi everyone,
I noticed that the PMDG 737-800 payload model available in the download section is incomatible with the NGX Version of the plane. It seems to overload
the aircraft. The result is, that, with a moderate to heavy loaded aircraft, you cannot reach decent FL's anymore, because the red overspeed and stell
speed bars are closing in on each other until there is no normal speed left and you either get a stick shaker or an overspeed warning, or both at the
same time. The -600 and -700 FS9 versions seem to run fine with the NGX. I havent tested the 900 so far.
I tried to config a new payload model for the NGX, just to get a reminder that I suck at it. I tried to convert the readings of the stations into the
payload editor.....
As far as I know, the weight is in lbs and the distance is in feet in both FSP and the aircraft.cfg.
[WEIGHT_AND_BALANCE]
reference_datum_position = 0.00, 0, 0.0
empty_weight_CG_position = -5.51, 0, 0.2
max_number_of_stations = 50
station_load.0 = 4550.0, 16.1, 0.0, 2.0
station_name.0 = "For Cabin"
station_load.1 = 7000.0, -5.9, 0.0, 2.0
station_name.1 = "Mid Cabin"
station_load.2 = 4550.0, -28.1, 0.0, 2.0
station_name.2 = "Aft Cabin"
station_load.3 = 7200.0, 15.9, 0.0, 0.0
station_name.3 = "For Cargo"
station_load.4 = 7200.0, -26.4, 0.0, 0.0
station_name.4 = "Aft Cargo"
My Problems are now:
-there is a weight specified in the aircraft.cfg, FSP has only an option to set pax numbers, but how am I supposed to know how many pax the NGX-800
can handle? Havent found a reference on that yet......of course, there are plenty of 737-800 seat maps around, but I dont know which configuration was picked by PMDG for development.....
-The aircraft.cfg positions are relative to the datum reference point while the FSP positions are relative to the CG, so for station 1, the position
is 10.59, 0.0 , 1.8, is this correct?
-Are the values really in pounds and feet? If I divide 2 * 4550lbs / 170 lbs and 7000lbs/ 170lbs I get some 93 pax for that plane, which is very little for a 737-800.
of course, the most favourable solution would be someone who is an expert on that finally making a payload model for that great plane. I am pretty
sure there is a demand.....
