On a few checklists, I have noticed that after 10,000 ft the checklist may say PAX signs to auto or off. Does auto work as it does on the ground, and automatically turn the signs on and off (when transitioning from smooth to turbulent air in the air), or should I be putting the signs to off and manually turning them back on? I'm sure there's more than one school of thought depending on the airline, but wasn't sure what the more common method was.

In real world the the pax signs are turned to on manually and not auto before each takeoff and landing. As soon as the plane reaches a safe altitude[not cruising level] the pilots then turn the signs to auto
