B-26 Marauder Weight and Balance/Station loads

Hi Guys,

I have been unable to find what the various weights are for. 3000 is probably bomb load and 180 and 170 are crew - but what do the other weights represent? I normally lower landing values to what an aircraft returning to the base AFTER a mission should be. Hence my need to understand what the values represent.

Bill,

Doing this from memory but it should be close.

This is for the FSX version only. The FS9 coordinates are slightly different.

station_load.0= 180, 12.608, -1.800, 0.000 //Pilot
station_load.1= 180, 18.135, 0.000, 0.000 //Bombardier
station_load.2= 180, 6.725, -2.000, 0.000 //Radio Opr
station_load.3= 180, 6.725, 2.000, 0.000 //Navigator
station_load.4= 170, -14.017, 0.000, 0.000 //Turret Gunner
station_load.5= 170, -21.641, 0.000, 0.000 //Rear Gunner equipment
station_load.6= 170, -29.594, 0.000, 0.000 //Rear Gunner
station_load.7= 3000, 0.200, 0.000, 0.000 //Bomb Load
station_load.8= 400, 19.535, 0.000, 0.000 //Bombardier Equipment/Gun/Ammo
station_load.9= 400, -21.641, 0.000, 0.000 //MG Ammo
station_load.10= 700, -6.518, 0.000, 0.000 //MG Ammo
station_load.11= 700, -6.594, 0.000, 0.000 //MG Ammo
station_load.12= 800, 6.825, 0.000, 0.000 //Radio/Nav Equipment
station_load.13= 180, 12.608, 1.800, 0.000 //Copilot
 
Man!
Those are some scrawny crewmen!

They need to EAT. Steak and potatoes ONLY. That'll put some weight on their bones!
:biggrin-new: :biggrin-new:

Have fun, all!

Unfortunately those young men did not have the luxury of eating steak and potatoes every night being they were in the middle of fighting a world war. I think they were probably happy to have anything at all to eat. K-rations and baloney sandwiches probably would have been the order of the day. It's no secret that the Air Corp ate a lot better than the infantry. If you look at lots of old pictures of the Army Air Corp crews it appears (anecdotally)that many young men were smaller than today's generation. I know my father was. His size didn't keep him from winning the Bronze Star. Besides, who could have fit into one of those belly turrets?

Milton,
what method are you using to site those weights into the aircraft? When I'm building an FDE, I use a nav light to site the location of the different stations. Placing those station loads at different locations really changes the flight dynamics which then need to be compensated for in the aircraft.cfg and airfile.
 
Mal998,

It appears that Milton has placed the various loads in the model where they actually were located within the aircraft. This is the normal method of computing weight & balance. This "combat load" should be reflected in the actual aircraft flight dynamics, and also in a realistic Flightsim FDE. By inspecting the aircraft CFG file you will also see where the fuel and oil is distributed.

If you fly with a minimal crew, various ordnance load outs, or less than full fuel, the weight & balance changes and must be recomputed to insure that the Center of Gravity is within limits for safe flight. This is a procedure which every real world pilot performs as part of preflight planning.

And it is true ... change the CG and the plane will have different flying characteristic. This is why in the Piper J3 you must solo from the rear seat only. In more complex aircraft you may have to use or move fuel from one tank to another to stay within a safe flight envelope.

Since the aircraft is my own model, I read the coordinates in gmax and transfer directly to the aircraft.cfg. :)

Of course they affect the flight model; that is a given, and intended.

I have been doing flight models for 16 years, but I also rely on Tom Falley (and others) who has type ratings in singles, twins, quads, and ATP jets to ensure our flight models are representative.
