What does it take for you guys to put up a real debate and answer questions?
What is the tolerance of commercial category pressure altimeters?
John stated they are "highly inaccurate".
Do you agree?

Please backup your reply with FAA and manufacturer data. I'll await
either reply and then post the real data for the readers to view.

And to this day I have not seen one credible, or rational explanation for THAT.

As to the accuracy of a pressure altimeter: considering the resolution of the adjustment which is 0.01" Hg increments and 1" Hg representing near enough to 1000', we could expect an accuracy in the order of +/- 10' if the instrument was perfect in every way.
In practise the accuracy would be somewhat worse than that.
A radar altimeter would be an order of magnitude better for very low altitude measurements and immune to air pressure anomalies produced at extremely low level, high speed flight.

The reason I ask is that it appears that all the discussions prior to this latest work have revolved around what the NTSB .csv shows as the last altitude (and other parameters) readings when it would be quite obvious to anyone actually decoding the data that extra readings existed.

The first decode of this data independant of NTSB was done in association with PFT members somewhat secretly ... 'readout2'
That particular decoding must have revealed the existance of the extra (incomplete) packet at the end of the raw file consisting of the altitude data we're discussing here now.
Have you acknowledged that data prior to W Stutts's decode and revelation of it and, if not, why?

Originally posted by ReheatTurbofan can argue the accuracy of a pressure altimeter versus a radar altimeter all day long as long as he gets instructions from his master.

The serial numbers were missing? How would you know that unless you have personally seen the FDR/CVR in question? Was there a news report/news release that specifically stated the "serial numbers were missing"?
Here is an alleged photo from the official US Department of Defense Pentagon 911 book of the alleged FDR planted on some guy's footprints. Perhaps you can see a serial number?

I don't see what you both are so worked up about? Have you even
studied the data trend that was uncovered?
