Climb gradient when no restrictions

[KrisJ 43]

In some older planes, eg. Dc-10, a climb gradient limitation is required in calculaction of take off and climbout performance. Question: is there a kind of default, minimum climb gradiet that should be assumed when charts does not specify one?

It would be great if anyone knows this problem and can assist.

ICAO has a minimum procedure climb gradient and I believe that it is 3.3 percent -  starting from 5meters above the departure end of runway.

This basically the same as 200ft / nautical mile.

Not sure about FAA has other rules for the U.S.

Thank you for this info.

Do you know if ICAO policy applies for european airline regardless departure airport? For instance for return leg to europe from US?

Anyone can provide US FAA climb gradient restriction?
