: Align the Rate Arrow (large black triangle on the inner scale) to 12 on the outer scale. Locate 21 on the outer scale. Directly below it on the inner scale, you will find 105, which translates to Problem B : If you cover , what is your groundspeed?
The E6B flight computer is a circular slide rule designed to perform a wide range of calculations, including:
You have 48 gallons of usable fuel on board. Your engine burns 12.5 GPH. What is the total endurance of the aircraft? Solution: 3 hours and 50 minutes (3.84 hours).
However, knowing the theory is different from applying it under pressure. That's why working through —practice problems with confirmed solutions—is the most effective way to build mastery. This guide provides just that: a collection of verified practice exercises covering time, speed, distance, fuel, wind, and airspeed, complete with step-by-step solutions.
Mastering the E6B Flight Computer: Step-by-Step Exercises with Verified Answers
The "calculator side" of the E6B uses a circular slide rule where the outer scale represents (or Fuel) and the inner scale represents Time . Problem A : You are flying at a groundspeed of and need to cover . How long will it take?
