E6b Flight Computer Exercises ~repack~ Access

Mastering the E6B "whiz wheel" is a rite of passage for every student pilot. Whether you're prepping for your FAA written exam or just want to navigate without a dead battery, these exercises will sharpen your manual flight planning skills. The Basics: Time, Speed, and Distance

The front side of the E6B is essentially a circular slide rule where the outer scale represents distance/speed and the inner scale represents time.

Problem 1 (Time En Route): You are flying at 150 knots (Ground Speed). Your destination is 250 nautical miles away. How long will it take?

Solution: Set the "Rate Arrow" (black triangle) to 150. Look for 250 on the outer scale. Opposite that, on the inner scale, you’ll find the answer: 1 hour and 40 minutes.

Problem 2 (Fuel Consumption): Your aircraft burns 12 gallons per hour. If your flight time is 45 minutes, how much fuel will you use?

Solution: Set the Rate Arrow to 12. Find 45 (minutes) on the inner scale. Look across to the outer scale to find 9 gallons. The Wind Side: Wind Correction & Ground Speed

The back of the wheel is used for wind vector solutions to find your Heading and Ground Speed.

Problem 3 (The Wind Mark): Wind is 210° at 30 knots. Your True Course is 180° and True Airspeed is 110 knots. Find your Wind Correction Angle (WCA) and Ground Speed. Steps: Rotate the dial to wind direction (210°).

Slide the grommet (center hole) to 100 and mark a dot at 130 (30 knots up). Rotate the dial to your True Course (180°).

Slide the card until your pencil dot is on your True Airspeed line (110).

Result: Read the WCA under the dot (approx. 8° right) and your Ground Speed under the grommet (approx. 84 knots). Essential Prep Resources

Mastering the E6B flight computer, affectionately known as the "Whiz Wheel," is a rite of passage for any pilot. This circular slide rule has remained a cockpit staple for over 80 years because it doesn't require batteries and can solve complex navigation problems in seconds.

The device is split into two primary parts: the Calculator Side 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.

Problem: How much time will it take to fly 120 Nautical Miles (NM) at a groundspeed of 100 knots?

Step 1: Rotate the inner scale until the "60" Index (the big black triangle) is opposite your groundspeed (100) on the outer scale. Step 2: Locate your distance (120) on the outer scale. Step 3: Read the corresponding time on the inner scale. Answer: 72 minutes (or 1 hour and 12 minutes). Practice Exercise 2: Wind Correction and Groundspeed

The wind side is used to find your Wind Correction Angle (WCA) and Groundspeed (GS) by plotting a "wind dot".

Problem: Find the Groundspeed and Heading for a flight with: True Course (TC): 130∘130 raised to the composed with power Winds: From 250∘250 raised to the composed with power at 15 knots True Airspeed (TAS): 112 knots Procedure: Set Wind: Rotate the transparent disk to 250∘250 raised to the composed with power under the True Index.

Mark Velocity: Mark a dot 15 units up from the center "grommet". Set Course: Rotate the disk so 130∘130 raised to the composed with power is under the True Index.

Adjust for Airspeed: Slide the background grid until your wind dot is on the 112-knot arc.

Read Results: Your Groundspeed is under the grommet (approx. 119 knots) and your WCA is shown by how many degrees left or right the dot is from the centerline. Practice Exercise 3: Fuel Consumption

Calculating fuel is critical for legal requirements and safety.

Mastering the E6B flight computer, often called the "whiz wheel," is a rite of passage for every pilot. While digital apps are convenient, the manual E6B is a reliable, battery-free tool that helps you visualize the relationships between speed, time, distance, and wind.

Below are exercises designed to sharpen your skills on both the calculator and wind sides of the E6B. Part 1: The Calculator Side (Time, Speed, & Distance)

The calculator side is a circular slide rule used for ratio-based problems.

The E6B flight computer, often called the "whiz wheel," is a manual circular slide rule used by pilots for flight planning and navigation. It consists of a Calculator Side for math problems and a Wind Side for vectoring. 🧭 Calculator Side Exercises

Use the circular scales. The outer scale (A) is for distance/fuel/speed. The inner scale (B) is for time. 1. Time, Speed, and Distance Review: Wind side practice with varied wind angles

Exercise A: You are flying at 120 knots. How long will it take to travel 45 nautical miles?

Step: Set the speed index (black triangle) to 12. Look at 45 on the outer scale. Answer: 22.5 minutes.

Exercise B: You travel 18 nautical miles in 9 minutes. What is your groundspeed?

Step: Align 18 (outer) over 9 (inner). Look at the speed index. Answer: 120 knots. 2. Fuel Consumption

Exercise A: Your engine burns 8.5 gallons per hour (GPH). How much fuel is used in 2 hours and 20 minutes?

Step: Set speed index to 8.5. Look at 140 minutes (2:20) on the inner scale. Answer: 19.8 gallons.

Exercise B: You have 35 gallons of usable fuel. Your burn rate is 11 GPH. How much endurance (time) do you have? Step: Set speed index to 11. Look at 35 on the outer scale. Answer: 3 hours and 11 minutes (191 mins). Wind Side Exercises

Use the sliding grid and the rotating azimuth to find your Wind Correction Angle (WCA) and Groundspeed (GS). 3. Wind Correction & Groundspeed Scenario: True Course (TC): 090° True Airspeed (TAS): 110 knots Wind: 180° at 20 knots Steps: Rotate the azimuth to wind direction (180°).

Slide the grommet (center hole) over a heavy line (e.g., 100). Mark a "wind dot" 20 units up from the grommet (at 120). Rotate azimuth to your course (090°).

Slide the grid until the wind dot is on your TAS line (110). Results: Groundspeed: Look under the center grommet. (~108 knots)

Wind Correction Angle: Note the dot's offset from the center line. (10° Right) True Heading (TH): TC + WCA = 100° 🌡️ Conversions & Altitudes

Small windows and scales allow for environmental corrections. 4. True Airspeed (TAS)

Exercise: You are at 8,500 ft Pressure Altitude. Outside Air Temperature (OAT) is +10°C. Indicated Airspeed (IAS) is 105 knots.

Step: In the "Pressure Alt" window, align 8.5 with +10°C. Look at 105 on the inner scale; read TAS on the outer scale. Answer: ~122 knots TAS. 5. Unit Conversions Exercise: Convert 50 US Gallons to Liters.

Step: Find the "US GAL" and "LITERS" arrows on the outer scale. Align "50" under the US GAL arrow. Answer: ~189 Liters. 💡 Practice Tips

Check the Units: Ensure you aren't confusing Gallons with Pounds or Nautical Miles with Statute Miles.

Sanity Check: If you have a headwind, your Groundspeed must be lower than your Airspeed. If it's higher, you likely plotted the wind backwards.

Pencil Matters: Use a fine-point pencil or a specialized E6B pen for the wind side to keep marks precise.

Part 4: High Performance & Weather – Density Altitude

As you move into complex aircraft, hot days at high altitude fields become dangerous. Density altitude (DA) tells you how your plane will perform.

Part 5: Emergency & Diversion Drills (Timed Exercises)

These are high-pressure E6B flight computer exercises to simulate real emergencies.

7. Recommendations & Next Steps

Review: Wind side practice with varied wind angles (crosswind vs. headwind).
Quiz: Timed TSD and fuel problems to increase speed.
Flight application: Plan a cross-country with E6B only, then compare to GPS GS and actual fuel used.
Advanced exercises: Off-course correction, radius of action, and true altitude conversion.

Exercise 2: Finding Groundspeed

Scenario: You pass over a VOR at 14:25 Zulu. You pass the next VOR (exactly 32 NM away) at 14:49 Zulu.

Task: Calculate your groundspeed.
Method: Align the 32 minutes on the inner scale (time) with 32 NM on the outer scale (distance). Look at the Speed Index (60 on the inner scale). The number on the outer scale above it is your groundspeed.
Answer: 60 knots. (Bonus check: If you cover 32 miles in 32 minutes, you are going 60 knots).
Advanced: You cover 48 NM in 24 minutes. Groundspeed? (Answer: 120 knots).

Part 3: The Wind Triangle (The Hardest E6B Exercises)

This is where most students quit. Solving for wind correction angle (WCA) and groundspeed (GS) requires visualizing vectors. Do these slowly, then speed up.
