Which you want to focus on (e.g., radius of action, off-course corrections) Whether you are using a mechanical or electronic E6B The type of aircraft or speeds you typically fly
The E6B flight computer remains a cornerstone of pilot training. Even in an era dominated by digital flight bags (EFBs) and GPS, mastering this manual tool is essential for passing FAA knowledge exams and ensuring cockpit redundancy.
You're flying from point A to point B, a distance of 120 nautical miles. If your heading is 090° (east) and your airspeed is 100 knots, how long will it take to reach point B?
E6B flight computer (or "Whiz Wheel") is a circular slide rule used for essential navigation and performance calculations. Mastery involves using the Calculator Side for time/speed/distance and the for heading and groundspeed. Core Calculations & Verified Exercises e6b flight computer exercises verified
Your engine burns 8.5 gallons per hour (GPH). You will be flying for 2 hours and 15 minutes. Question: What is your total fuel burn? Steps: Align the inner "60" with 8.5 on the outer scale. Locate 135 minutes (2h 15m) on the inner scale. Read the fuel burn on the outer scale. Verified Answer: 19.1 gallons ( Part 2: Wind and Groundspeed (Wind Side)
The Learn to Fly blog features a "CFI Brief" specifically on enroute questions requiring an E6B, which closely resemble what you will find on the FAA knowledge exam. These exercises cover:
You fly a distance of 42 nautical miles (NM) in 18 minutes. What is your groundspeed? Step 1: Locate 42 on the outer scale. Which you want to focus on (e
The wind side of the E6B is where the "whiz wheel" truly earns its name, allowing you to solve complex wind triangles. The process can be broken down into a simple, repeatable procedure.

Before jumping into specific exercises, it's crucial to remember that your E6B is actually two tools in one. Understanding what each side does is the first step in a "verified" practice approach:
But simply owning an E6B isn't enough. You need —problems with known correct answers—to build confidence before your checkride.
