EDP's switch on 747 aircrafts???
Hi,

I read somewhere that EDP's switch on 747 (classic) has 3 positions: ON/Depress/OFF.
-What is the function of this switch in the depressurization mode?
-Why this switch is different than the one in other aircrafts (just 2 positions: ON/OFF).

Thank you
Best regards.
