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,

Thanks for posting the new csv file of system parameters. I looked through it and as expected all systems are normal. There isnt any indication of impact with any object.

Bleed Pressure
AC Bus Volts
Fuel Flow
Tank density
EGT
N1, N2, N3
Engine vibration
Inlet Temps

etc...

All operating normally and within limits.

Not sure why the EPR ACTUAL show 0 for last two subframes as the engines were definitely producing thrust. You can see this in N1, N2, and N3 along with EGT and Fuel flow (some pilots actually prefer to set thrust with fuel flow instead of EPR as the flow is instantaneous instead of a slow change in EPR). The other EPR parameters also show thrust.

Anyway, as i said, there is no indication of impact with any object, this includes the tree/bush top at pole 1 which GL's love to pull out their ass claiming you can see the semi-circle made by the top of the bush being ingested into the engine. This would be reflected in the Engine vibration, EGT and perhaps fuel flow. It is not. Their theory is bunk as usual.

By the way, can you upload AOA (angle of attack) when you get a chance? TIA.

Hi Rob,

Hi Warren,

Your welcome.

OK, I'll add the following parameters:
AOA HEAT ON - L
AOA HEAT ON - R
AOA PROBE HEAT - L
AOA PROBE HEAT - R
CORRECTED AOA
INDICATED AOA
INDICATED AOA3
INDICATED AOA4
INDICATEDAOA2
