The E6B flight computer, often called the "whiz wheel," is a manual circular slide rule that has remained a fundamental tool for pilot training since World War II. While modern digital apps exist, the FAA and other aviation authorities still require mastery of the manual E6B for Private Pilot Knowledge Tests.
The "Slide Rule" side of the E6B is essentially a circular slide rule. It allows you to solve ratio problems. The key is the "60" index.
Scenario: You fly 78 NM on a heading of 045°. At that point, you realize you are 4 NM right of course.
Step 2: Rotate the disk to align 13 (inner) with 26 (outer scale).
