I assume you are asking how to arm the Emergency Escape Slide in a passenger airliner?
After you close the door, there is usually a lever that you pull to activate the arming mechanism for the Escape Slide. The Airbus has a lever on the door. Others have it above the door.
Door or hatch
A block hour is the time from the moment the aircraft door closes at departure until the moment the aircraft door opens at the arrival gate following its landing.
those are doors used to access an aircraft, like the passenger door on an airliner.
It varies according to the aircraft.
Most of the time it called a door. Sometimes but rarely it maybe refered to as a hatch
They are stamped into the door frame, you can't remove the arm rest. However, if you're wondering how to get to the INNER mechanism of the door, you have to remove the outer door skin. Instructions are elsewhere.
Remove inner door panel and replace complete door check assembly
are you talking about the little arm that comes out of the door and attaches to the door frame? because that's really simple. there should be a little pin that connects the that arm to the frame of the door, you pull that out and it should come right off.
Through the door,just like any aircraft.
Most helicopters have a door just like any aircraft.
a arm, naval, and aircraft base
Adjust the length of the arm or move the door closer.
