WHere to find stations for nose and main gear

[JimC]

Hi all,

If I'm reweighing my Skymaster, where do I find the stations for the nose and main gear? I can't find it in my 1970 T337E manual anywhere.

I found the W&B for the last time my plane was weighed. It had the most bizarre formula. It was

87 - (NGW x 96) / GW + 65 = 137.08

That's my published c.g: 137.08 inches.

There's no mention of where the 87, 96 or 65 came from.


NGW = nose gear weight, 500.0 lbs
GW = gross weight, 3218.0 lbs.

Can anyone explain this?
