ASA E6B-CIRC – Circular Flight Computer

Designed for both precision and convenience, ASA’s E6B-CIRC Circular Flight Computer provides fast and reliable manual calculations for pilots at every level. With its compact 6-inch diameter, smooth rotary dials, and matte finish for pencil markings, it is ideal for flight planning, training, and in-flight problem solving.

Unlike slide-rule-style computers, the circular design simplifies common tasks like unit conversions, fuel planning, and crosswind corrections—making it especially useful during FAA written exams or while flying at higher altitudes in faster aircraft.

• Performs time, speed, distance, rate, fuel, altitude, airspeed, air temperature, and pressure pattern calculations
• Wind side solves for true course, ground speed, true heading, and off-course corrections
• Matte finish allows temporary pencil markings for step-by-step problem solving
• Vinyl case and instruction booklet included
• Made in Korea | 6" Diameter | UPC: 855734008385

Cleaning Tip: Use water and a cloth to clean pencil markings. For tough marks, use mild soap or rubbing alcohol.

Want extra training? ASA’s Pilot’s Manual: Ground School (ASA-PM-2) includes an entire chapter with illustrations and guided instruction on using the E6B flight computer.

The E6B-CIRC is a pilot favorite for its ease of use, compact format, and visual clarity—perfect for planning and performance insights.
