This j-hook can be overridden with a button next to the gear handle in case there is some sort of malfunction with the system. Once overridden, the handle can be moved and still actuates the gear retraction. From what I can remember, that is all that prevents the gear from being retracted on the ground. Somebody please correct me if I'm wrong.[/IMG]
Correct but you still need hydraulics and we don't turn them on until after the engines have been started. Unless we are doing the first flight rudder check but at SKW 99.99% of the time only the CA’s do the FFOD Originating Check and IF we let the FO’s do it we are there observing so they get it right. It’s a very long series of systems checks and FO’s just don’t do them that often, they’re plates are already full in the morning.
BTW, do you Lakers turn the hydraulics on after you start the APU? Why? You don’t need them unless you drop the parking/emergency brake? Or maybe he was trying to suck the Hydraulic Gear doors back up.
