Gravity32,
The static port can only be mounted on the fuselage side where the air is relatively undisturbed.
If it were mounted on the nose of the aircraft then the speed of the aircraft would have a huge effect on the altimeter reading.
The point of the link I provided was to indicate the following sources of error for the instrument and that they are inherently
error prone and in the case of an aircraft, specifically when standard operating procedures are not adhered to.
The link shows the equation variables which apply to any barometric altimeter.
All this aside, lets say that Boeing gives you a calibration chart for the altimeter and this chart shows that the final reading
was incorrect by a factor of ten.
What significance would this have in relation to the aircraft crashing into the Pentagon or overflying the Pentagon or any other factor
regarding the crash.
My opinion is that the 757 crashed into the building and this was deliberate. The hijackers would probably not have reset the reference
datum to local conditions on the descent.
What will confirmation of the calibration data prove?
That is in my opinion the million dollar question.
ETA: You may find this interesting.
