737 GENERAL -- ENTRY DOOR EXTERIOR OPERATION General
You open and close an entry door manually with the control handle. While open, a hinge lock mechanism holds the door in the open position.
The cabin crew puts the door slide warning pennant across the door window if the slide is armed.
Open the Door - Exterior Operation
An escape slide is on the inside, lower part of the entry door. If the slide girt bar is in the armed position, the slide will deploy automatically as the door opens. Look to see if there is a door slide warning pennant (orange) in the door window. The pennant is across the window when the slide is armed. Make sure that the escape slide is not armed before you open the door.
The door swings out of the door frame when it opens. Make sure that the area outside of the door is clear.
You must pull the exterior door control handle from the recess position to engage the door drive mechanisms. Turn the handle 180 degrees in the clockwise direction. The door moves to the cocked open position.
At this point, any more effort on the door control handle will not produce more door motion. The door control handle has gone through its full motion. Release the control handle and allow it to return to its recess by spring force.
