Using the C-5 the late and great Rey Lopez created.
Question: With autopilot set at 6000 feet as a example,
the C-5 cannot maintain the alt setting. Goes from
400 feet above to 400 feet below air traffic controller's
instructions. Then when instructed by traffic controller
to go to 4000 feet, the aircraft starts dipping and rising
500 feet and more. Then it goes to 600 feet-to 800feet-
and so on. Just up and down.
Any ideas for a correction on this problem?
I tried setting the autopilot to 2900 feet, but this does
not correct the problem.

One other question; what is correct landing speed for C-5?

Thank you in advance

in the aircraft.cfg find this section

[pitot_static]
vertical_speed_time_constant=100

It might have a low number set there, like 2, raise it to 50 or even 100,
this sets the speed at which the autopilot reacts, higher is slower but it
keeps it from bouncing around.

If that whole section isn't in the aircraft.cfg, then I assume it
defaults to something?

Can you simply add that section and adjust to settle down an airplane
that is skittish in pitch?

Thanks,
