Military AI Works

I have a few aircraft that appear to be floating above ground.
Which part of the contact points do I change to either raise or lower stance of aircraft?

Can anyone assist?

Its the fourth parm that you need to alter, as in the highlighted one here :-
point.0=1, -19.50, 0.00, -5.70, 1181.1, 0, 0.6349, 46.8, 0.3000, 2.5, 0.9100, 10.0, 10.0, 0, 260.0, 260.0

Thanks Steve for your reply.
