Using an E6B flight computer (the "Whiz Wheel") is a core skill for pilots, essential for passing the FAA knowledge test and managing in-flight scenarios without electronics . To master it, you need to practice both the Calculator side (ratios) and the (vectors). CYA Aviation 1. The Calculator Side (Front) This side works on a "60-to-1" ratio principle. Time-Speed-Distance (TSD): Align the black triangle (index) on the inner scale to your Groundspeed on the outer scale.
Set speed to 120 knots. To find time for 40 nautical miles (nm), look at 40 on the outer scale; the inner scale will point to 20 minutes. Fuel Consumption: Align the index to your Gallons Per Hour (GPH)
Set burn to 8.5 GPH. To find fuel used in 45 minutes, look at 45 on the inner scale; the outer scale shows approximately 6.4 gallons. Conversions:
Use the marked points for Nautical Miles (NM), Statute Miles (SM), and Liters to Gallons. 2. The Wind Side (Back)
This solves for Wind Correction Angle (WCA) and Groundspeed. Rotate the wheel to the Wind Direction under the True Index. Mark Velocity:
Move the slide so the grommet (center hole) is on a flat line (e.g., 100). Count up and mark a dot at the Wind Speed Set Course: Rotate the wheel to your True Course Align Airspeed: Slide the card until the wind dot rests on your True Airspeed (TAS) Groundspeed: Read the number under the grommet.
Count the degrees left or right from the centerline to your dot. 3. Practice Scenarios 219° @ 27kt Find Heading & Time 210° @ 15kt Find Heading & Time 180° @ 20kt Find Groundspeed & WCA Tips for Success
To master the E6B flight computer, you should focus on its two distinct functional areas: the Calculator Side (circular slide rule) and the Wind Side (compass rose and slide). Effective practice involves mastering specific "navigation systems" rather than just isolated math problems. Core Exercise Categories
To improve, structure your exercises into these three primary domains:
Time-Speed-Distance (TSD): Use the outer scale (Scale A) for distance and the inner scale (Scale B) for time.
Exercise: Align the 60-index (rate pointer) with a known groundspeed, then find various distances to see how long they would take.
Fuel Consumption: This works identically to TSD problems but replaces distance with fuel and speed with fuel burn rate.
Exercise: Set a burn rate of 8.5 gallons/hour and calculate the total fuel needed for legs of 45, 90, and 120 minutes.
Wind Correction (The "Wiz Wheel"): Use the back side to find your Wind Correction Angle (WCA) and Groundspeed (GS).
Exercise: Practice "marking the wind dot." Set wind direction, mark speed up from the center grommet, then rotate to your course to find the drift. Recommended Training Guides
While electronic devices like the CX-3 Flight Computer offer speed and precision, mastering the manual E6-B "whiz wheel" is often considered better for developing a pilot's fundamental understanding of flight physics. Unlike digital tools that provide instant answers, the manual E6-B forces you to visualize the relationships between variables like wind drift and ground speed. Why Manual Practice is Often Preferred
Conceptual Clarity: The graphical nature of the manual E6-B helps students visualize the "wind triangle," making it easier to grasp how heading and airspeed must change to maintain a desired course. e6b flight computer exercises better
Reliability: Analog computers never run out of batteries. Many instructors prioritize manual proficiency because an examiner may "fail" your electronic devices during a checkride to see if you can still navigate safely.
Efficiency: Once proficient, many pilots find the manual wheel faster for making quick, multiple "what-if" calculations compared to menu-diving on a digital screen. Effective Exercise Strategies
To improve your skills, focus your exercises on these three core task groups: The E6B Flight Computer Made Easy
The E6B flight computer is a fundamental tool for pilots, but mastering it requires more than just understanding the theory—it requires practice. Many student pilots find the manual "whiz wheel" intimidating at first, but with structured exercises, it becomes an intuitive extension of flight planning.
Here is a comprehensive guide to E6B exercises designed to improve your proficiency, speed, and accuracy.
In the age of glass cockpits, iPads mounted to every yoke, and GPS databases that update automatically, a strange question arises in flight training: Why do we still need the E6B flight computer?
The answer is simple, yet profound. While an electronic flight bag (EFB) is efficient, the manual E6B (whether the classic aluminum "whiz wheel" or the electronic CX-3) forces a level of cognitive engagement that apps cannot replicate. However, owning the tool isn't enough. The magic happens when you commit to rigorous E6B flight computer exercises. Doing these exercises better—with intention and repetition—transforms you from a button-pusher into a true aviator.
Here is why focused practice with the E6B leads to superior stick-and-rudder skills, sharper aeronautical decision making (ADM), and a safer flight experience.
Practice consistently with timed drills; focus first on accuracy, then reduce time targets. Want a printable set of 20 mixed problems and answers for drills?

While it may appear complex, it is simply a circular slide rule based on the 60-to-1 ratio, making it an efficient tool for quick in-flight and planning calculations.
To get better at using your E6B, try these structured exercises and techniques. 1. Speed, Time, and Distance Reps
This is the most common use for the "calculator side" of the E6B. Use the "speed index" (the large triangle, usually at 60) to set your rate. Exercise A: Estimating Ground Speed
Problem: You cover 23 nautical miles in 10 minutes. What is your ground speed?
Solution: Set 10 (inner scale) against 23 (outer scale). Read the speed (138 knots) above the speed index. Exercise B: Finding Time En Route (ETE) Problem: How long will it take to fly 245 NM at 150 knots?
Solution: Align the speed index with 150. Look for 24.5 (245) on the outer scale. Read the ETE on the inner scale (98 minutes or 1:38). 2. The Wind Side: Finding Heading and Ground Speed
The "wind side" helps you correct for crosswinds to determine your actual track over the ground. Using an E6B flight computer (the "Whiz Wheel")

Master Your Whiz Wheel: Why E6B Flight Computer Exercises Make You a Better Pilot
The "Whiz Wheel," or manual E6B flight computer, is more than just a relic from the past; it is a fundamental tool for any student pilot. While digital apps like ForeFlight or electronic E6Bs offer speed, mastering the manual E6B through dedicated exercises builds a deeper, more intuitive understanding of flight physics that no calculator can replicate. 1. Master the 60-to-1 Rule
The calculator side of the E6B is built on a logarithmic scale centered around the "Speed Index" (the number 60 in a black triangle). This represents the 60 minutes in an hour.
Exercise: Practice converting time-distance problems by setting the Speed Index to a specific groundspeed (e.g., 100 knots) and reading how many minutes it takes to fly 25, 50, and 100 nautical miles.
Benefit: This reinforces the concept that flight planning is essentially a series of ratios. 2. Visualize Wind Correction Angles
One of the most difficult concepts for students is the relationship between True Course (TC), Wind Correction Angle (WCA), and Groundspeed (GS).
Exercise: Use the "wind side" of the E6B to solve for unknown groundspeed. Practice with a variety of crosswind and tailwind components.
Benefit: Unlike a digital entry, the physical movement of the E6B slide helps you see how a strong crosswind "pushes" your aircraft and necessitates a specific crab angle to maintain your course. 3. Calculate True Airspeed (TAS) and Density Altitude
Electronic displays often give you TAS automatically, but understanding why it changes with altitude is critical for safety.
Exercise: Use the small windows on the calculator side to find Density Altitude and TAS by aligning Pressure Altitude with Outside Air Temperature (OAT).
Benefit: These exercises teach you how air density affects performance, helping you predict how your plane will handle on a hot day at a high-elevation airport. 4. Build Mental Math Redundancy
Many pilots rely on the calculator, but the E6B handles fuel flow, endurance, and burn rate without batteries.
The Exercise: "You have 24 gallons usable. Your engine burns 9.2 GPH. How long can you fly?" Do ten variations of this, alternating between finding fuel used, time, and flow rate.
