@ the autopilot guys
MiG 21 BIS SAU is equipped with a SAU23ESN autopilot.
It lowers and stabilizes the controls.
Its possible to do an autoland with minimums 40m.
There's also a rescue button , when the pilot is pushing it, the autopilot will recover the aircraft. If you will set an minimum altitude in radar altimeter it will also recover when you're below that altitude.
For more questions I've to ask a friend.
