SGR (Still-air ground range)

SGR Calculation

Calculations of SGR are as follows;

consumption rate (lb/kg/etc per hr) / ground speed (kts) = lb/kg/etc per nm


ground speed (kts) / consumption rate (lb/kg/etc per hr) = nm per lb (or whatever you’ve used)

Consumption Rate

This is calculated by taking TAS and dividing by SAR (Still air range)

TAS / SAR (nm per lb) = lb per hour


TAS * SAR (lbs per nm) = l per nm
