Everyone but you on this thread confirms that the radalt will be accurate in this case because the plane is not tilted, is not closing too rapidly with the terrain and, close to impact, is not passing over significant buildings or steeply sloping ground. It was also proved reliable by checking every landing on the FDR file, and found to give -6 feet in every case while taxiing.
You started this thread claiming that the Pressure altimeter would not be accurate operating "outside of it's envelope".
Many agreed. I would agree too.
Then you posted the actual speed on page 4. See the above quotes. The Pitot-Static system was operating well within it's capability without error and is confirmed with airspeed v. groundspeed analysis as pointed out in this thread.
Do you think that Radalt only measures from the ground? What happens if a building is on the ground? Does the Radalt measure through that building to the ground?
If you feel Radalt tracking capability is based on vertical speed, how does that apply when crossing over multiple obstacles with a 90 degree side? Do you know basic trigonometry?
Perhaps this is the reason you do not wish to answer my questions?

(also, if you want to talk amongst real pilots, try not to use the word "tilted".... rather bank, roll, pitch, yaw, crab... etc.... these are the terms real pilots use.)
