POH Performance is a collection of free, ad-free, source-available aircraft performance calculation apps maintained by POH Performance LLC. It covers use cases including Beechcraft Baron/Bonanza, Cessna 172/182, Kodiak, PA28, TBM, and weather radar beam calculations. It is more of a vertical development project for the aviation community than a general-purpose developer platform: its core goal is to turn performance tables and charts from flight manuals such as POH/OM/AFMS into interactive calculators for preflight and in-flight reference.
The tech stack is straightforward: the frontend is a single-page WebApp built with JavaScript, HTML, and CSS; the iOS/Android versions are packaged via Cordova; and the backend is lightweight PHP for weather retrieval and settings backup. The browser version can run locally, and once installed on mobile devices, it can be used offline. On the developer side, it provides a unified framework, aircraft-specific pages, the Ptable data format, and a dedicated POH Performance digitizer for handling distorted charts, extracting tabular data, and generating internal encodings.
The apps themselves are free and ad-free, and the code license is free for non-commercial use. However, this does not mean it is completely unrestricted open source: derivative works, public distribution, and commercial use require permission from POH Performance LLC. When Textron Aviation aircraft data is involved, separate authorization and payment to Textron may also be required.
The advantages are that the source code is available, the documentation and contribution process are fairly detailed, multiple platforms are supported, and there are dedicated tools for the pain point of digitizing aviation performance data. The drawbacks are also clear: the use case is highly specialized; adding new aircraft requires substantial manual data entry, review, and testing; some licensing terms are complex; self-hosting the backend requires PHP deployment; and project maintenance depends mainly on volunteers, so scheduling and support capacity are limited.
It is suitable for pilots, general aviation aircraft communities, aviation data volunteers, and developers who are familiar with JavaScript/HTML/Git and willing to maintain aircraft data over the long term. It is not suitable for teams looking for a general low-code platform, commercial APIs, or enterprise-grade SLAs.
The collected text does not provide information about access from mainland China. Domain availability, SourceForge access stability, and mobile app store distribution cannot be determined, so this is marked as unknown.
