E6B practice is a free mini-app created by David Megginson for fans of the classic aviation E6B circular slide rule and for student pilots. Its core goal is not to support a general developer workflow, but to help users practice wind-side and calculator-side E6B problems. It is best suited to people who still need to learn manual aviation flight-computer calculations.
The app offers two types of practice: wind-side problems and calculator-side problems. Users can click, tap, or press a key to reveal the answer and then move on to the next question, making the interaction very straightforward. The page also notes a new feature added on 2024-03-01: wind-side problems now include step-by-step solutions for CR-style analogue flight computers and do not rely on a sliding card; calculator-side problems use the same solution method for both styles. This is useful for learners who want to understand the solving process.
From a developer-tooling perspective, the page does not provide information about supported languages, frameworks, APIs, or SDKs, nor does it mention embeddability, plugin support, or third-party integrations. The project provides a GitHub link and welcomes bug reports and pull requests, indicating an open collaboration channel, but the license, deployment method, and self-hosting support are not clearly stated in the text.
Pricing is very clear: this is a free mini-app. The author does not put it behind a paywall; instead, users who want to show appreciation are encouraged to donate to a local women’s shelter, a homeless shelter, or organizations that help refugees and displaced people, such as the Red Cross, MSF, or UNRWA. Support mainly relies on GitHub issues and pull requests, making it suitable for users who are comfortable with community-style feedback.
The advantages are that it is free, lightweight, and focused. It is especially suitable for student pilots doing practice questions and aviation enthusiasts reviewing E6B operations. The newly added step-by-step solutions also improve its educational value. The drawbacks are its very narrow use case, basic documentation, and lack of visible APIs, SDKs, self-hosting guidance, multilingual support, or structured course materials.
The page does not provide hosting location, network accessibility, or payment information, so its accessibility from China is unknown. Since the tool is free and has no payment flow, payment friction is not an obvious issue. If access is unstable, alternatives include local aviation training materials, E6B mobile apps, or reviewing the code directly via an open-source repository.
