The CR-3 E6-B ASA Computer is an indispensable tool designed for pilots, aviation students, and instructors seeking accuracy, versatility, and ease of use in their aeronautical calculations. From basic arithmetic operations and flight planning to the most complex in-flight calculations, this calculator offers a comprehensive solution for your needs.

Constructed from high-quality materials and featuring easy-to-read letters, the CR-3 E6-B ASA Computer combines durability with unmatched efficiency, accuracy, and convenience in the manual flight calculator market.

The calculator side uses conventional slide rule procedures to quickly solve multiplications, divisions, and unit conversions. In addition, it incorporates specialized scales for essential calculations of time, speed, distance, fuel consumption, altitude, airspeed (TAS), air temperature, and pressure patterns.

On the other hand, the wind computer side provides an intuitive graphical method for solving wind-related problems and displaying the answers in a clear and useful manner. Use this section for simple addition and subtraction calculations, as well as for determining true wind, en route winds, true heading and ground speed (GS), true heading and true airspeed (TAS), and heading correction calculations. The matte surface of this side allows for pencil annotations during use and is easily wiped clean for the next calculation.

It is an excellent tool for use during flight planning, flight training, or study, and is approved for use during FAA theoretical exams. Pilots operating faster aircraft at higher altitudes will find this calculator especially useful for obtaining accurate information about external atmospheric conditions and their effects on flight performance.

A handy vinyl case is included for protection and transport, as well as a detailed instruction booklet so you can get the most out of all its features.
