“How does a flight attendant unlock the cockpit in emergency scenarios,
e.g., both pilots have fallen unconscious if the door is locked from the inside?

♦♦♦♦♦♦

• When the correct code is entered.  A chime rings in the cockpit which alerts us that somebody wants in.
• We can either unlock the door or switch it to “deny”.
• If we select deny, the door will hard lock for 30 minutes.
• Then the flight attendant can try again if he wants to.

If we don’t do anything, neither select deny nor unlock the door then the door will unlock after 30 seconds.

It seems to be a pretty good system and it’s not secret at all.

Key Biblical Concepts:

• salvation
• I stand at the door
• election
• knock

New procedures have been put in place since the terrorists hijacked airliners on 9/11.  One of those changes has been the security of the pilots.  If you have watched the flight attendants initiate a final closure of the cockpit door before takeoff, or watched them enter the cockpit during flight, you may have been reminded of that fateful day on 9/11.

Have you had this thought as well . . . . With the cockpit door securely locked during flight, what would happen if someone needed to get into the cockpit during an emergency — such as — both the captain or first officer going unconscious due to a lack of oxygen —  or if they both experienced some other kind of a medical crisis — or due to an act of covert terrorism in the cockpit?  How does someone get in to help, revive, or even replace them with another pilot who may be on board?

That question has been asked and answered.  That is a real question that has been addressed by those who designed the newly secured doors of the cockpit.

The design of that locked cockpit door allows entrance through various steps which can be taken by the flight attendants — and is this is not top-secret information — an article on this very question states. . . .

• There is a keypad at the door.
• When the correct code is entered.  A chime rings in the cockpit, which alerts us that somebody wants in.
• The pilot(s) can either unlock the door or switch it to “deny.”
• If a pilot selects deny, the door will hard lock for 30 minutes.
• Then the flight attendant can try again if he/she wants to in 30 minutes.
• If the pilot doesn’t do anything — the pilot neither selects deny — nor unlocks the door —  then the door will unlock after 30 seconds.

There is a code to get in!  — There is a code that must be entered at the door.

There is a code to get it — that code is no secret — it has been and continues to be announced worldwide — punch in J-E-S-U-S.

That word — J-E-S-U-S — indicates that somebody, anybody, whosoever-will would like to enter into that eternal kingdom.

The angels of heaven rejoice when that code is entered and heard throughout the halls of heaven.

Hebrews 2:10 states that “this captain” —  the captain of salvation — will always open the door.

Unlike — in contrast to — the security measures aboard today’s passenger jets . . . .

• There is never a denial of any who seek entrance.
• There is no hard lock for 30 minutes — to see if you really meant it.
• There is no wait and try again later — In fact, a later time is never suggested — Today, if you will hear His voice.
• It is not that the captain passively does nothing, but He purposefully opens the door to all who seek entrance.
• Within a fraction of a second, the door unlocks — and like the thief on the cross — the woman at the well — the Ethiopian Eunuch — a Roman centurion — the Philippian jailer —  the mad man of Gadara — Ruth — t is reported that even a terrorist gained access – Saul/Paul. . . .  all who call on Jesus are granted full access into His presence.
