The wind side requires a pencil to plot a "wind dot." This side solves the wind triangle to find your True Heading (TH) and Groundspeed (GS). Exercise 6: Calculating Heading and Groundspeed True Course (TC): 090° True Airspeed (TAS): 120 knots Wind Direction/Speed: 180° at 20 knots E6B Steps:
Wind Correction Angle is +10°. True Heading is 100° (090 + 10). Groundspeed is 108 knots. Practice Matrix: Challenge Yourself
Before diving into calculations, you must understand the two sides of a mechanical E6B: e6b flight computer exercises
If the wind is a headwind, your groundspeed must be lower than your TAS. If the E6B says otherwise, you've made a rotation error.
123.5 knots
If your groundspeed is 115 knots, how long will it take to fly 64 nautical miles (NM)? Exercise B:
Align the 60-minute index arrow with 85 (representing 8.5) on the outer scale. Locate 75 minutes on the inner scale. Read the value on the outer scale. 10.6 gallons. Exercise 5: Endurance (Time to Fly) The wind side requires a pencil to plot a "wind dot
Note the dot's offset from the center line. ( 10° Right ) True Heading (TH): TC + WCA = 100° 🌡️ Conversions & Altitudes
Flight computer proficiency is a perishable skill. Spend 10 minutes a week running through these exercises to maintain your speed for your next checkride or flight review. If you want to practice specific scenarios, let me know: Your aircraft type or average cruise speed Groundspeed is 108 knots
Read the corresponding directly below it on the inner scale (B). Practice Problems
This requires "dropping the dot" to find your Wind Correction Angle (WCA). The Setup: Set Wind Direction under the True Index Mark Wind Velocity up from the center grommet. True Course under the True Index. Slide the wind dot to your True Airspeed (TAS) Challenge: 160° at 20 knots . Your True Course is 270° (West) and your TAS is What is your Wind Correction Angle and Groundspeed? 3. Fuel Burn Calculations Fuel planning is critical for safety and completing a navigation log
