Aal77 Fdr Decoder Program, Decodes almost 4 more seconds Options

[wstutt]

I have created a new program to decode AAL77's raw FDR file.

I am making it available for download along with it's source code and some output files from the program.

You can read more about it here

It decodes almost 4 more seconds of data than what appears at the end of the NTSB CSV file.

I welcome suggestions for any more parameters you would like decoded or any other features you would like added.

I will also be discussing this on the J.R.E.F. "AA77 FDR Data, Explained" thread as well as here.

Hi Warren,

Yes, I agree, positive roll means right bank (right wing down). You can also cross-check this with heading change. The data conflicts with the ASCE damage report requiring a left bank of roughly 5 deg IIRC.

Unfortunately, I have no way to verify the other 11 flights in your data. However, the last flight does verify with our data.

I spoke with Ralph Kolstad (American 757 Capt) and Rusty (United 757 Capt), they verified and confirmed my article before i published it.

Also, it is not unusual to keep the cockpit door closed during flight. I have gone on many 4-5 hour flights never leaving the cockpit. I've even done many trips single and twin engine prop from NY to Florida, Memphis... etc, 8-10 hours of flying, with one pee break at midway point when stopping for gas. I know many pilots who go hours without leaving their seat.

Many pilots dont like to leave the flight deck. Its called "The Walk Of Shame" for a reason...lol

Also keep in mind, some of the previous flight locations if i recall were LA-ORD-MIA-IAD, These are relatively short legs. 2-3 hours. Hit the bathroom before boarding, bring your lunch (which most pilots do to save some cash and eat more healthy than airline food), and you never need to leave your seat. There is also plenty of room to stretch on a 757 Flight Deck.

You are correct about the short flights. The longest section of FDR data for all flights (engines on to engines off) is only 4 hours and 34 minutes. If the pilots never left the flight deck during the previous 11 flights, then it would appear to me that either:
(1) The flight deck door was never opened while the engines were running.
(2) The flight deck door open/closed state was not sensed and recorded correctly. e.g. The door sensor reports closed when the door is actually open.
(3) The flight deck door was opened, but for less than 4 seconds each time.

I am open to suggestions.

I have only just started reading through the thread you included a link to.
