The E6B Descent Planner provides a fully functional circular slide rule for use in real time descent planning. Using one finger, and with a single turn of the rotating inner disk, pilots can easily perform calculations to determine top of descent distance, angle of descent, vertical descent rate required, glide ratio, maximum glide distance based on altitude, plus many other calculations that are not commonly associated with a mechanical E6B.

FlyQ+ EFB is a top-rated aviation app because it makes your flying easier and safer by thoughtfully integrating powerful features in a way that minimizes the number of screen taps and uses larger fonts to increase readability. New features such as a glide ring, graphical weather briefing, ability to download two data cycles, and a navlog that expands/collapses airways/SIDs/STARs make flying safer and easier than ever before! The Global Digital Map shows airports, airways, airspace, navaids, and waypoints from all around the world. Text rotates so it's always right-side up and the level of detail adapts to the zoom level. Our exceptional "4D Predictive Weather" system uses a Timeline and Altitude Slider to help you analyze weather at different times - both past and future - and at different altitudes. 17 weather layers from both the Internet and ADS-B (e.g. Radar, Icing, Turbulence, PIREPs, Winds Aloft, Surface Winds, Surface Analysis, Satellite, and more), many tied to the Timeline and Altitude Slider, give you unprecedented pre-flight and in-flight safety. Supports more than 20 ADS-B and in-panel devices: Stratus 3, Avidyne, Dynon, Stratux, and more. The exclusive Augmented Reality (AR) feature provides situational awareness you'd previously only seen in sci-fi movies.  The Slingshot wireless system means FlyQ+ supplies maps, plates, and apt diagrams wirelessly to certified systems from BendixKing. The Visual Logbook and Post Flight Playback / Analysis Graphs add a whole new dimension to your flying. Optionally connect with your friends to "see" and even replay their flights. CFI's can track student progress and remotely send endorsements. Other key features include split screen, 3D synthetic vision, plates on the map, more than 4,600 airport diagrams, rich Documents support, extended runways, distance measurement, fuel prices, NOTAMS, wind-optimized flight planning, and plates for Mexico and Central America.

ReceptionRating · Positive reviews · Number of ratings

FlyQ+ EFB holds the better App Store score, 4.1 against 3.5. That said, the two scores are not equally well evidenced: FlyQ+ EFB has 892 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 92% of E6B Descent Planner's written reviews are positive against 72% of FlyQ+ EFB's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

E6B Descent Planner ships an update every 9 months, FlyQ+ EFB every 2 months. The most recent releases landed on September 4, 2026 and September 26, 2026 respectively.
