Hi Shayan,I never hit Auotflight until ready for the auto pilot to take over personally. I arm Nav and Prof, then after I'm tracknig the FD and all is stable I will usually then hand it off to AP.

The minimum altitude to engage the Autopilot on the MD11 is 400ft AGL , have a read of the limitations section of the FCOM

FLEX1978 is correct, if you press autoflight to engage the AP below 400 ft, it WILL shutoff ap guidance. You have to wait until you are 400 or higher.

I always found it curious that people engage the AP below 400ft. are those first 10 seconds so tedious?
