AviatJet 647 Aristo Air Navigation Computer.

A particularly complex slide rule for air navigation, the AviatJet was developed from earlier flight computers such as the previous example.at above. It has scales for distance–time–speed problems, fuel consumption, wind triangle computations, and for converting between British/US and metric systems. There are also scales for true air speed, true altitude, speed of sound and Mach number, which is the velocity divided by the speed of sound.
