In an era dominated by GPS, glass cockpits, and digital flight planning applications, the traditional analog E6B flight computer remains a staple of pilot training. Often referred to as the "whiz wheel," this circular slide rule has guided aviators since World War II. While electronic E6Bs and tablet apps offer instant answers, regularly practicing manual E6B flight computer exercises is one of the most effective ways to sharpen your foundational aviation skills.

If your GPS fails mid-flight, or if ATC issues a sudden "Direct to" heading that changes your groundspeed, you won't have time to pull out an iPad. But if you have consistently performed manual E6B exercises, your brain will intuitively know: True Index (Heading) [ 360° ] | |
You see the literal divergence between indicated airspeed (IAS) and TAS as altitude increases.
Exercise: Set a burn rate of 8.5 gallons/hour and calculate the total fuel needed for legs of 45, 90, and 120 minutes. You know your E6B flight computer exercises are
Always do a sanity check – WCA rarely exceeds 15–20°, GS should be within ~20 kt of TAS for moderate winds.

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.
The e6b is a circular slide rule designed specifically for pilots. It allows users to perform a variety of calculations, including:
