Given: Distance = 120 NM, Groundspeed = 110 knots. Find: Time en route (minutes).

However, owning an E6B doesn't make you a navigator; practicing with it does. Many student pilots fail their cross-country planning checkrides not because of poor flying skills, but because they fumble with time-speed-distance calculations or wind correction angles under pressure.

Exercise 1.2: 4. 21.35 gallons 5. Time = 2.5 hr → 21.75 gallons

Step: Find the "US GAL" and "LITERS" arrows on the outer scale. Align "50" under the US GAL arrow. Answer: 💡 Practice Tips

All exercises assume no electronic GPS assistance; only a manual circular slide-rule E6B or approved electronic E6B.

The device is split into two primary parts: the for math like fuel burn and time, and the Wind Side for determining groundspeed and wind correction. Practice Exercise 1: Time, Speed, and Distance The most common use of the calculator side is solving the (Distance = Rate x Time) equation.
