Computer Exercises Verified: E6b Flight

: The scales use relative values (10 can mean 1, 10, or 100), meaning you must use common sense to place the decimal correctly based on the flight context. The Wind Side: Vector Solutions

120 kts

: Find total fuel required for a flight lasting 2 hours 17 minutes (137 minutes) at a burn rate of 8.2 gallons per hour (GPH). Rate Arrow to 8.2 on the outer scale. Find 137 (or 2:17) on the inner scale. Read the outer scale directly opposite. 18.8 Gallons

~4400 ft (varies slightly by E6B model)

Slide the card so the wind dot rests on your TAS line (112 knots).

The Learn to Fly blog features a "CFI Brief" specifically on enroute questions requiring an E6B, which closely resemble what you will find on the FAA knowledge exam. These exercises cover:

✅ Colder air → lower true altitude. Approx 4% per 10°C from ISA. e6b flight computer exercises verified

To give you a sense of the format and challenge level, here are three sample problems from that test:

Distance is 185 Nautical Miles (NM). Groundspeed (GS) is 120 Knots. Task: Calculate the time en-route.

The E6B flight computer remains a cornerstone of pilot training, serving as a reliable analog fallback when modern avionics fail. Mastery of this mechanical slide rule is required for passing FAA knowledge exams and ensuring cockpit safety. : The scales use relative values (10 can

Read the corresponding time on the inner scale directly below 78. 40.7 Minutes (40 minutes, 42 seconds) 2. Fuel Consumption Calculations

After leveling off, you have 38 gallons of usable fuel remaining. Your power setting results in a fuel burn of 11.2 GPH. Question: What is your maximum flight endurance? Verified Solution: 3 hours and 23 minutes (203 minutes). E6B Steps:
