AUTO mission with LOIT_TIME param

Hello to the community

I test my hexacopter with an AUTO mission which consists of LOIT_TIME adding 10seconds in each.

It was highly unstable pitching up and down upon reaching each waypoint.
My setup is
Pixhawk 1
My copter weight is over 20kg.

I want to know how the LOIT_TIME works

Do you mean LOITER_TIME?

Thankyou for reply
