Hi I just joined, as you can see. (IMG:style_emoticons/default/rolleyes.gif) I got hooked on your forum in the middle of the night, while reading about the FDR and Flight 77 Flight Deck Doors not being open. I understand the part about this FDR not being for the actual flight. I got a few knit-picker debunkers, that have me going around in circles about stuff. I asked them to read your whole thread first, before commenting. This one has me stumped. You know more about it than I do, can anyone here explain it to me, so that I can give the poster a snappy comeback? (IMG:style_emoticons/default/handsdown.gif)
Yes, the FLT DECK DOOR value was CLOSED for the entire flight. You got me. Oh wait, the same parameter is the same for ALL recorded 12 flights. The pilots never got anything to eat or left the flight deck to go to the bathroom, not even on the long LA - DC flights. As a matter of fact, the door is NEVER recorded OPEN for any point ever when the FDR is recording. Very strange. The pilots must have worn those astronaut diapers.
Thoughts and advice: There are 42 HOURS of flight data in Warren RO. It is wise to check your observations for the last minutes or flight against the other 41 hours of recorded data. I don't know why the value is CLOSED for the entire 42 hours (that is one for the pilot folks to hash out), but if the parameter never changes and reason dictates that it should at some point, then I can conclude one of two things. The parameter was not being recorded and a default value was being stored, or the parameter being recorded is not what some think it is.
and after my reply, I got this:
The Flight Deck door parameter is also listed as "Not Working or Unconfirmed" on page 13 of the FDR report:
I'll see if I can track down the file 911files was working from.
The poster pulled it from another site, and only posted a thread link, instead of where this information really came from. I questioned their motive. I am a truth seeker. NOT A DEBUNKER or a TROLL. I just have to deal with them.
Lots of the other members, found this forum very interesting, and thanked me.
If you want to check out the thread, so that I can prove my honest intentions, read it here.
We're all on the same side.

Wow, this is GOLD, Truly gold! This configuration is fool proof and knocks out any of the excuses the
GL's make about "jammed switch", "faulty switch", etc.
In the event a proximity switch fails, it will show OPEN, or a LOGIC 1!!!!
If the switch is defective it cannot complete the circuit either.
Even if the door is slightly open (not completely shut), it will show open. This is because the circuit is ONLY complete when the door is tight against the jamb.
On top of this, the wiring to the breaker panel and pilot controls would have made it SIMPLE to interface
with the FDR wiring. In other words, the retrofit to install the door switch would not require extensive
plumbing, wiring, backbending to get a voltage signal from the circuit to the FDR port input.
JFK, if I may I'd like to contact you further about this circuit and diagrams.
