Gravity32,
Fair enough. You are concerned about the speed affecting the altimeter reading.
Now once again, lets say the calibration data shows that the aircraft was flying at speeds exceeding the calibration envelope.
What does the FDR say about the speed of the aircraft and what would be the significance of this excess speed and barometric altitude error in relation to the weight of evidence?
This is what I am trying to understand. What will this data refute or confirm.?
