Mark a dot 25 knots up from the center grommet using the grid lines.
Locate the "Airspeed Correction" window on the calculator side.
Align the "60" index under 8.4 on the outer scale. Find 45 on the inner scale; the outer scale will show 6.3 gallons .
You pass over your first checkpoint and note that you have traveled 24 NM in exactly 11 minutes. Question: What is your current groundspeed? Verified Solution: 131 knots. E6B Steps:
The wind side of the E6B is where most students struggle. The error usually comes from drawing the wind dot incorrectly or misinterpreting the True Course. Let’s run a standard FAA-style question with a verified answer. e6b flight computer exercises verified
Find 28 on the outer scale and align it with 14 on the inner scale. Look at the 60 pointer (1 hour) on the inner scale. Read the number directly above it on the outer scale. 120 Knots. Exercise 2: Calculating Time En Route
You traveled 45 NM in 20 minutes. What is your groundspeed? Steps:
Look at the pencil dot to determine the Wind Correction Angle (WCA) on the curved lines. The dot is to the right, indicating a right wind correction. Wind Correction Angle (WCA): +10∘positive 10 raised to the composed with power True Heading (TH): 100∘100 raised to the composed with power ( Groundspeed (GS): 118 Knots 4. Altitude and Airspeed Corrections
To become proficient in using the E6B flight computer: Mark a dot 25 knots up from the
Mastering the E6B flight computer, often called the "Whiz Wheel," requires consistent practice with time, speed, distance, fuel, and wind calculations. These verified exercises and step-by-step methods are designed to help you prepare for the FAA Private Pilot Written Test and real-world navigation. 1. Basic Calculator Side (Time, Speed, Distance) The front side of the E6B uses a 60-to-1 ratio
Look at the pencil dot to see how many degrees left or right it sits from the vertical centerline. This is your .
If you got 81 knots, you likely misread the numbers (reading 36 instead of 135) or placed the inner number under the wrong outer number. Remember, the numbers on the outer scale usually represent the "answer" (Distance or Speed), while the inner scale represents the "variable" (Time).
The core of E6B work involves the 60:1 proportion used to compute time, speed, or distance when any two are known. Use the following exercises to master this fundamental skill. Find 45 on the inner scale; the outer scale will show 6
Your aircraft burns fuel at a rate of 8.4 Gallons Per Hour (GPH). Your flight time is 2 hours and 15 minutes (135 minutes). E6B Steps:
A rotating bezel and sliding grid used for solving wind triangle problems (calculating heading and groundspeed based on wind direction/velocity).
Rotate the inner disk to align the "60" rate arrow (Speed Index) with (representing 112) on the outer scale. (representing 45) on the outer scale. Read the time on the inner scale directly below 4.5. Verified Answer: ~24 minutes. Flight Training Central 2. Fuel Endurance (Calculator Side) Calculate the endurance of an aircraft with 53 gallons of fuel and a burn rate of 9.8 gallons per hour Set the rate arrow (60) to on the outer scale. (53 gallons) on the outer scale. Read the time on the inner scale. Verified Answer: ~5 hours and 24 minutes. Flight Training Central 3. Wind Correction & Groundspeed (Wind Side)
True Heading=True Course−Left WCA or +Right WCATrue Heading equals True Course minus Left WCA or plus Right WCA Groundspeed: 123 KT Wind Correction Angle: +9° True Heading: 099° Best Practices for E6B Accuracy
5 hours 24 minutes.
Rotate the wheel to place wind direction (360°) under the True Index. Mark a point 20 units up from the center (grommet).
