AAL77 FDR Decoder Change Log

Version
Changes
1.0
First version.
1.1
Changed the conversion formulas for the LATERAL ACCELERATION, LONGITUDINAL ACCEL and VERTICAL ACCELERATION parameters so that the values produced by the program exactly match the NTSB CSV files instead of having a maximum difference of 1 in the last decimal place.
