Airfoil AoA

This app collects no data about you and makes no network connections of its own. It keeps one small record on your device, and nothing else.

What this app stores

On your device only, in the app's own storage:

• Which lessons you have marked done, so the Learn list can show a check mark and the next lesson up.

That record never leaves your device and is not tied to an account or an identifier. To clear it, choose Clear check marks at the bottom of the Learn list, or in About (the info button at the top of the Learn list). Deleting the app also removes it.

The app is built with AutoPilot's shared library, whose quiz and rating-request features keep three more records under the names aerokit.weakness.v1, AutoPilot.review.lastAskedDate and AutoPilot.review.lastAskedVersion. This app has no quiz and never asks for a rating, so it never writes them; the names are listed here only so that what the code contains and what this page says agree.

What this app does not do

• No account, sign-in, or email address
• No analytics, tracking, or advertising
• No third-party SDKs of any kind
• No network requests. The lessons are bundled, and the air around the wing is computed on your device as you move the slider. The app works fully in airplane mode.
• No location, camera, microphone, contacts, photos or health access. The app has no permission prompt at all.
• No purchases or subscriptions

Links out of the app

The About screen has two links, Privacy policy and Support, and both open this page in your browser. The app itself sends nothing with either link: no identifier and nothing about you travels with it.

Support

Questions, bugs, or something you think the app has wrong: admin@flywithautopilot.com. Say which lesson or screen and which angle of attack, along with your device and iOS version.

Airfoil AoA is ground study for angle of attack: how a wing makes lift, three popular explanations that get it wrong, why a wing stalls at an angle and not at a speed, and where drag comes from. Its flow pictures are computed approximations, and its lift and drag numbers are illustrative, not any real airplane's. It is not for use in flight: your airplane's limits, the handbooks and your flight instructor come first.
