Oz runways W&B

[biggles5128]

Have just downloaded oz runways, could someone assist me with setting up the weight and balance for a J230. It requires a lon and a lat data entry. Have done many W&B in the past but can't seem to get the correct data to create the envelope.

Have to modify for your own BEW and aircraft moment arm (will be close to this)

 

Lat is constant, I.e. No wing lockers or multiple wing tanks.

Might be dopey Q but how did you work out lon ?

For & aft CoG limits at BEW & MTOW (The 23o only uses a 4 point envelope)

 

 

[jetjr]

Ok, but from POH they give same limits at all weights?

 

Wouldnt that give square envelope?

Got it sorted, was neglecting to use indexs rather than arms
