Description
The ASA CX-3 Flight Computer is a mechanical E6B-style calculator designed for pilots who need quick, reliable wind correction, fuel burn, and distance-to-climb solutions without batteries or electronics. These slide-rule computers have been standard equipment in general-aviation cockpits for decades because they work anywhere and require no charging—essential backup tools for cross-country flight planning and inflight problem-solving.
Typical users include student pilots building fundamentals, IFR-rated aviators keeping a backup calculator handy, and experienced pilots who prefer hands-on computation for weight-and-balance or true airspeed verification. The CX-3 format works for Cessnas, Pipers, and Beechcraft aircraft where traditional E6B functionality remains relevant. Keep one on your kneeboard or in your flight bag as insurance against avionics failure or dead batteries on the flight deck.
