An E6B flight computer is traditionally an analog device resembling a combination slide rule and slide wheel that performs calculations specific to aviation. For example, an E6B can be used to calculate heading and groundspeed after taking into account forecast winds. An E6B is also used to calculate data used for performance planning such as density altitude. Our version goes beyond the analog E6B and even beyond all other E6B apps by including functionality to calculate time, rate and radius of turns, pivotal altitude (great for flight training use), and more. ## FlightReady E6B Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource126/v4/9e/88/2b/9e882b2b-3b5e-8c99-772a-a6304c3cb208/c8e61e56-ef68-4af3-b7b0-e4bc267dd6f5_iphone-65_1.png/1242x2688.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource116/v4/1d/7b/c9/1d7bc9a7-a16d-8c6c-1a2b-5d05f850b0d8/c8a7cc5a-bad1-4de1-b772-69c832ddb4a2_iphone-65_2.png/1242x2688.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource126/v4/24/fc/c6/24fcc61a-fb69-d1a9-a12f-024bcdca7449/96e08f94-e019-4bc4-8b81-6a5f324bf655_iphone-65_3.png/1242x2688.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource116/v4/5a/42/93/5a429392-faaf-61b2-abf4-d11998d28ae1/458470f1-ef24-41c6-8ec8-f193e73a6a69_iphone-65_4.png/1242x2688.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource116/v4/48/82/b8/4882b8f4-9a1d-7e9f-2571-0e5deff9a08a/49152550-6b94-44fa-b9f0-e889d3ada754_iphone-65_9.png/1242x2688.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource126/v4/d9/8d/ec/d98dec6a-4106-8def-f662-6524abc55530/cf1324e8-c9c5-4973-ac1f-0f72f6ad2787_iphone-65_5.png/1242x2688.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource126/v4/eb/9f/6a/eb9f6a81-530e-8bd5-aa9b-efe6847d6849/03df36a0-8a51-4c12-8d5e-a1adbf2d5a9d_iphone-65_6.png/1242x2688.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource116/v4/fa/ac/80/faac80a3-68f0-4464-e5ae-3e6d75eb4f67/0ecd1bcf-89d6-40eb-9bdd-c2b7d4625e5c_iphone-65_7.png/1242x2688.png) - [Screenshot 9](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource116/v4/60/51/10/60511039-363e-f649-ceb5-a824575d9718/6211e634-dd13-46c5-8265-ff78a4e1cf16_iphone-65_8.png/1242x2688.png) - [Screenshot 10](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource116/v4/00/c6/40/00c6405e-b147-d6ee-080b-66f56acf01bc/d919013b-4cdf-4751-bf94-36dacc9a36aa_Simulator_Screenshot_-_iPhone_15_Pro_Max_-_2024-01-23_at_12.13.35.png/1242x2688.png) ## FlightReady E6B Rating Breakdown in United States - 5 stars: 912 (86%) - 4 stars: 92 (9%) - 3 stars: 21 (2%) - 2 stars: 5 (0%) - 1 stars: 31 (3%) ## FlightReady E6B Reviews in United States ### ***** "Nice app." Includes The function is necessary to plan Flight. -- 367-80, 2024-03-09 ### ***** "Excellent" I use this all the time, easy to use. It has everything i need in one app. -- Rlhjeh, 2023-09-13 ### ****- "Calculation problem?" Update: Reply received from the developer. Great to hear from them and no idea why I didn’t receive the original reply they say they sent. This review and reply process is poorly designed (by Apple) … but that’s a separate issue. Updated to 4 stars because it’s a well designed app that is very easy to use and the reply is appreciated. Kudos for that. The issue with no guidelines or instructions provided remains. The vast majority of the functionality in the app is perfectly straight forward. If you can use a real life manual e6b this will be a no brainer. This is faster and usually easier. It’s a pretty good app. But the lack of any user manual makes a couple key calculations either very difficult to verify or too easy to use incorrectly (and receive the wrong output as a result). For the record, I understand the calculations well enough to do them manually with paper and pencil. A user quick guide would likely solve any remaining confusion. Or at least allow verification of accuracy. -- Jfs071999, 2022-11-29 ### *---- "Pop ups" Trying to use this app and every time I back up it asks me to review the app! Brutal. Oh and the review requires a nickname and all have been taken, 6 attempts so far! Seriously -- 9&87$9&6@65-99, 2022-10-18 ### ***** "Low work load" Love this app use it on my iPad 10.2. Much faster, and way less workload in cockpit then regular electronic flight computer and way better then spinning the wheel and struggling to read it. So that makes for a safer flight. -- n93ster, 2022-10-07 ### ***** "Saved me a lot of time!" Love this flight computer. Extremely user friendly and awesome! -- June Air, 2022-08-29 ### ***** "Top free" Top free calculator so far -- miladmaz, 2021-12-27 ### ***** "Nice E6B" A nice E6B. Developer is responsive and works to update and maintain app long term. -- K4Co, 2020-09-30 ### ****- "No Seconds??" I like this app. Clean and it remembers values set throughout the different views However, I’m disappointed that any time measurements (distance over time, etc) only has HH:MM and will not include seconds. Despite the top review from 2 years ago mentioning this, it’s still not added. Disappointing for a $10 app. -- dylanlive, 2020-09-14 ### ****- "Well laid out but just one point to improve" The app is well laid out and easy to understand and determine flight plan information. I do with the flight “Time” calculation determines exact Leg Time in seconds like on some other calculators because when doing some cross country flight plans, those seconds could result in small fuel consumption calculation discrepancies that could add up. -- WingmanAviator, 2020-07-12 [View all FlightReady E6B reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## FlightReady E6B Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | United States | Navigation | #49 | | Top Paid | Canada | Navigation | #89 | ## FlightReady E6B Discovered Keywords ## Apps Similar to FlightReady E6B - [SkyTimer](https://apptail.io/app/skytimer-APv/united-states) - [NRST](https://apptail.io/app/nrst-Pzxc/united-states) - [FlashPass](https://apptail.io/app/flashpass-HHed/united-states) - [Holding Pattern Computer](https://apptail.io/app/holding-pattern-computer-KHed/united-states) - [Virtual VOR-DME](https://apptail.io/app/virtual-vor-dme-UAJd/united-states) - [Sporty's E6B Flight Computer](https://apptail.io/app/sportys-e6b-flight-computer-Kaae/united-states) - [Holding Pattern Trainer](https://apptail.io/app/holding-pattern-trainer-nbae/united-states) - [Nav Trainer Pro](https://apptail.io/app/nav-trainer-pro-Cdae/united-states) - [AOPA Mags](https://apptail.io/app/aopa-mags-jnve/united-states) - [Avidyne IFD100 10.3](https://apptail.io/app/avidyne-ifd100-103-ezel/united-states) ## FlightReady E6B Available In - [United States](https://apptail.io/app/flightready-e6b-fdae/united-states) - [Canada](https://apptail.io/app/flightready-e6b-fdae/canada) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
