Quiz: Flight Planning with Sporty’s E6B

1 min read

There are many aviation calculations required for preflight preparation and when planning a cross-country trip. In the early days, pilots used a mechanical circular slide rule, called an E6B. Electronic E6B calculators came next, which were more intuitive to operate and provide more accurate results.

During flight training, you’ll learn to plan your cross-country flights first by hand and use the E6B each step of the way. You’ll also find it to be a handy companion when studying for the FAA knowledge exam. It will assist with flight planning questions and you can bring your electronic E6B into the testing center to use during the actual test. The electronic E6B is equally useful when in the airplane, to help determine actual winds aloft, true airspeed, fuel burn, and descent planning. 

We’ll use the Sporty’s electronic E6B flight computer in this quiz when calculating flight planning and navigation questions. You can use any E6B flight computer to answer this quiz, though you may see minor differences in the results due to rounding. For a comprehensive guide to the questions in the quiz plus instructions describing all the remaining functions and features, read the Sporty’s E6B Flight Computer Manual.

    Funny, for the first question, my Sporty’s iPad E6B gives a Density Altitude of 187′. ????

    Thought I’d play for fun and games, I have an older sporty’s E6B handheld, plus the app on my phone. It was interesting to read the density altitude description…My Old handheld gave an answer of 175 (once I looked at the correct line ;-) ) The app on my phone gave an answer of 187. Different logic in each.
