Default RE: FineTuning Jets CG

Harley, I have never quite understood this method of CG checking wherein "fly inverted" if no down is required you are properly CG'd. I have always worked it as a percentage of MAC. Fine tuned based on landing speed.

Can you point me in the direction of a good explanation of the inverted flight method, how and why it works? Or someone with some expertise in this area explain?

Thanks,

Sean
Hi Sean. Correct or not, I "get" the inverted test method. And %mac is something I've used since I was 15, then tweaked based on longitudinal stability. But I must confess I am completely lost with your reference to tweaking based upon landing speed.

Help me out here? Thanks, Don.
