The E6B Flight Computer (often called the "Whiz Wheel") remains a fundamental tool for aviation training and real-world flight planning. While digital flight planning apps are prevalent, the ability to manually calculate critical flight parameters—such as groundspeed, heading, fuel burn, and density altitude—is a required skill for student pilots and a safety backup for seasoned aviators.

Climb from 2,000 ft to 9,000 ft at 500 fpm. Ground speed = 90 kt. How far before top of climb (TOC) to start?

Comprehensive verified exercises typically fall into two domains, each demanding its own set of procedures.
