Mr. Magoo, what the poster said in 15 makes no sense in the light of post 17, which is the operational procedure for re-entry.
A combination lock and keypad on the out side does no good if the keypad lock can be overridden from the inside.
The keypad in this case was locked out, thus no access for re-entry to the cockpit was granted.
How is this a solution to the problem?
Sorry. I can’t help you.
