Aircraft centre of gravity

[IanH 0]

I have just loaded Airbus A320/321/300 and noticed that the centre

of gravity is beyond the nose which make landing difficult.

Cannot adjust via weight and fuel is there an easy solution?

I am using FS9 on XP.

Which plane are you refering to?

If you are refering to the wilco vol.1, go to the start menu, and you should have a wilco folder that will help you setup the fuel required, and the weights including passengers and cargo all depending on your altitude and trip distance.

Good luck.

No, it is the Airbus series that comes with Holiday destinations but no amount

of altering the weight will get the centre of gravity nearer to where it should be! Other models such as the Opensky 757 are affected, but the PMDG 737

are fine. It has to be something in the aircraft cfg but no amount of fidddling

seems to work.

Any further help would be greatly appreciated.

many thanks

Hello Ianh,

When opening the "Fuel and Payload" window (Aircraft - Fuel and Payload, in the FS main menu), if you can see that the Center of gravity is too much close to the nose of the plane, go to the FS9/Aircraft/Your aircraft directory, and open the file aircraft.cfg.

In the § airplane_geometry, set the parameter wing_pos_apex_lon to 16 (the exact number is to be tested, because the greater the value of wing_pos_apex_lon, the more backwards the Center of gravity moves).

You can then check, in the Fuel and Payload window, that the Center of gravity is now correctly at the middle of the plane, above the wings.

Bests,

Philippe

Hello Philippe,

Thanks for the tip.

Ian, you will need to add this line to the Airbus aircraft.cfg as they are not there.

The 320 should be about 19.25

So add the following line to the aircraft.cfg for the a320 CFM in the airplane geometry section.

wing_pos_apex_lon = 19.25

Dear Shaun,

many thanks for your advice.
