Project Airbus a380 - CoG problems?

Featured Replies

Ooops - more haste, less speed; sorry, it's not the PA version, it is the one downloaded with the file a388abus.zip in the AVSIM library!!

 

I notice in the Fuel & payload settings that the CoG is right on the nose, no matter how I change the fuel balance. There is only one load entry, but changing that doesn't help either.

 

I haven't actually tried flying the aircraft yet, so don't know if it going to have problems because of this - I can't see any other comments about this here, or when I Googled either, but does anyone else who has this aircraft see the same thing?

 

Thanks,

 

Martin


LATER:  OK, having backed up just in case, I just substituted the station load part in the aircraft.cfg weight and balance section with the PA version and now the CoG is where it should be.

Martin,

 

The normal position of any aircraft's CoG should be at or around 25% chord but in FS9 (and possibly also in FSX) the CoG is very often a relative position in relation to the "reference_datum_position" which can be anywhere, dependant on where the developer has decided to position it. All other attributes like, e.g. the gear, engine thrust, lights, fuel, passengers, etc. are all positioned relative to this "reference_datum_position".

I agree with you that a CoG on the aircraft's nose is not really "as real as it gets" but it does not automatically mean that your aircraft will not fly as the developer intended it to do. Moreover, moving only the existing CoG position by any means, especially in the above relative setup, will most certainly have unpredictable results, both on the ground and in the air.

 

I would therefore like to suggest that you try to fly your aircraft as is or was and then report back in this thread.

Hi.Thanks - I always assumed that a CoG showing on the propeller image in FS9 meant problems - but I am sure you are right, that is not necessarily so.

 

I didn't change any of the CoG data in the a/c, just the stations list, and the plane flies just fine. I could try with the original, just as an experiment though.
