The rapid escalation of fuel costs has required our commercial airline carriers to take drastic steps to remain profitable. Cutting services and reducing schedules are commons practices but fuel is the one constant which they cannot reduce or cut. Accurately measuring your fuel usage is something they can control and the Brodie non ferrous aluminum aviation Bi Rotor Plus is the perfect solution. The compact, lightweight construction and extreme accuracy make it a favorite for equipment manufacturers and airlines alike. No other aviation meter can be mounted horizontally or vertically and perform like the  Brodie Aviation BiRotor Plus.
