I was quite surprised about one (all?) of doors on my latest Air Berlin flight. In particular:

  • the "Door locking indicator" was empty (black),
  • the "Cabin pressurized" light was not lighten and
  • the "Remove before flight" red strip was not removed.

red strip reading “REMOVE BEFORE FLIGHT”

(I am the owner of this picture and I authorize anyone to use it for any purpose except illegal activity.)

The plane landed safely and there was no noticeable in-flight change of air flow/pressure etc. Still, I wonder if the described situation is a violation of some in-flight procedures or at least odd in any way?

  • $\begingroup$ How long a flight was this? In other words, was it just an up and right down flight to get between two relatively close airports? $\endgroup$

    $\begingroup$ I did a Google search using "How many aircraft emergency exits can be inoperative?" and it appears that it's legal to dispatch some aircraft with one inoperative. For example, fsims.faa.gov/wdocs/policy%20letters/pl-001_r03_d00.htm. It appears that some restrictions may be required. $\endgroup$

    $\begingroup$ @trejder are you talking about the "cabin pressurised" light on the door? That may simply be part of the reason the door is inoperative... As for removing the pin, not really as that is an indicator that the door is inoperative and will restrict the use of the door. $\endgroup$

    $\begingroup$ I can't tell from this picture where the pin (and attached "remove before flight" strip) was actually placed. The thing does need to be kept somewhere during flight; it's not removed from the aircraft entirely. $\endgroup$ Commented Apr 2, 2017 at 23:32

The safety pin is in its stowage position - ie. where it is supposed to be stored when not in use, as you can see in this video. The red streamer is usually tucked away out of sight, but some airlines seem to leave it visible. Also, it appears from your photo that the arming handle is over to the right, ie. in the 'armed' position, as it should be in flight.

The Door Locking Indication is green-lettering-on-black for LOCKED, as you can see at 0:28 in this video, or red-lettering-on-black for UNLOCKED. But that lettering may not be very evident unless you are quite close to the door and looking almost directly at the indicator.

As far as I am aware, the Cabin Pressurized light is not normally illuminated in flight - it flashes red if-and-only-if the door handle is moved towards the OPEN position AND the cabin is pressurized, as you can see at 1:04 in this video.

  • $\begingroup$ You have managed to explain almost anything, thank you. As for the second part -- since I was staying in a quite long toilet queue I had pretty much enough time to actually stare directly into the "Door Locking Indicator" and I'm 100% positive that there was absolutely nothing inside, neither red nor green and no text. It was just a black, empty strip. Since we managed to figure out that these doors were inoperative, this may be a repercussion of that fact. $\endgroup$
