Why Bother with Manual E6B Exercises in the Digital Age?

Before diving into the exercises, let’s address the elephant in the cockpit: foreflight and GPS. If your iPad overheats, dies, or tumbles out the window, your manual E6B (and the skills honed by these exercises) becomes your lifeline. Furthermore, physically manipulating the wheel builds an intuitive understanding of relationships (e.g., how a 10-knot headwind affects groundspeed) that apps obscure. These E6B flight computer exercises are brain training for the sky. e6b flight computer exercises

Tips for Practicing with These Exercises

• Always verify units (KT, NM, GPH, USG).
• Practice the wind-side plotting steps slowly: set wind direction, mark wind speed from center, rotate to course, slide vector to center, read WCA and groundspeed.
• Cross-check results with vector math when learning.
• Time conversions: decimal hours → hours + minutes (0.25 h = 15 min).
• Use answers above as checks; small differences may occur depending on rounding and specific E6B design.

Exercise 6: Finding Wind In-Flight (The “Double Drift”)

Scenario: You are flying HDG 315° at 110 knots TAS. You look down and see your ground track (Course Made Good) is 320°. Your groundspeed (from GPS or VOR timing) is 125 knots.

• Task: Determine the actual wind velocity.
• Method:
  1. Set HDG (315°) under the True Index.
  2. Center the grommet over your TAS (110).
  3. The difference between HDG and Track is 5° (Right). Place a dot for your GS (125) 5° to the right of the center line, vertically where 125 knots sits.
  4. Rotate the dial until the dot lies exactly on the center horizontal line.
  5. Read the wind direction under the True Index.
  6. Measure the distance from the dot to the center grommet for wind speed.
• Answer: Wind = Approximately 275° at 22 knots.

Part 1: Time-Speed-Distance Drills (The Fundamentals)

Before touching the wind side of the E6B, you must master the "whiz wheel" side. The formula is simple: Distance = Speed × Time. But the E6B uses a slide rule, not a calculator.

Quick Answer Key (summary)

• Ex 1: GS 120 KT; 1 h 15 min.
• Ex 2: Endurance ≈ 4 h 14 min; fuel used 17.0 USG.
• Ex 3: TAS ≈ 108 KT.
• Ex 4: Heading ≈ 047°; GS ≈ 125 KT (approx).
• Ex 5: Heading ≈ 310°; GS ≈ 99 KT; time ≈ 55 min.
• Ex 6: Required ≈ 13.4 USG; available 28 USG → OK.
• Ex 7: WCA ≈ 23°; heading ≈ 113°; GS ≈ 84 KT.
• Ex 8: Leg A example: heading 066°; GS ≈ 83 KT; time ≈ 29 min; fuel ≈ 4.11 USG.

. On the physical tool, you align the "60" pointer (representing 1 hour) on the inner scale with your groundspeed on the outer scale. Exercise A: If your groundspeed is , how far will you travel in Exercise B: You need to fly . At a speed of , how long will it take? 2. Fuel Consumption

This uses the same scales as distance but replaces "distance" with "gallons" and "speed" with "gallons per hour (GPH)." Exercise C: Your engine burns . How much fuel is used during a flight of Exercise D: You have of usable fuel. If you burn , what is your maximum endurance in minutes? 3. Visualizing the Wind Triangle

The most complex part of the E6B is the "wind side." You must determine your Wind Correction Angle (WCA) to find your Heading, and calculate your Groundspeed based on headwind or tailwind components. Answer: 26

The following graph visualizes a typical wind correction scenario: True Course (TC): 090∘090 raised to the composed with power (Due East) True Airspeed (TAS): Wind: 045∘045 raised to the composed with power (A quartering headwind from the northeast) Answer Key A (Distance) B (Time) C (Fuel) D (Endurance) Wind (GS) Groundspeed: -8∘negative 8 raised to the composed with power 082∘082 raised to the composed with power
