Disclaimer: This app is useful in verifying if CG is within limit after a "Last Minute Change" of load distribution from that shown in the electronic loadsheet. Since the index calculation in this app is based on computer translation of the manual loadsheet which does not have any negative values (see the excel file for details), the results will look illogical in case of extreme forward or aft loading. Therefore its use is limited to last minute changes in load distribution rather than generating a loadsheet from scratch. The data used in this app is for ATR 72-500 operated by PIA. Since aircraft weight and company policies vary, results may not be valid for aircraft operated by other operators.
