The mass of an aircraft and the location of its centre of gravity are vital information required before flight. 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. The index calculation in this app is based on computer translation of the manual loadsheet, therefore the MAC can differ from the electronic loadsheet by a value of +1%.

It is fairly simply to use. Just fill in the required values and click the "Calculate" button, CG will be automatically plotted. Click here for a functional demo .

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.

Note: The graph and CG Plot requires Android 4.4 (KitKat) or above. Lower versions can be used if only weight and index calculations are required.
