Find nearby instrument approaches in IMC.
Warning This app should not be used as a replacement for safe preflight planning practices. All weather data is not guaranteed to be accurate, and the instrument approach data is not guaranteed to be complete. Always check the official sources before flying, especially when venturing into IMC.
This is a web app that allows you to search for nearby instrument approaches in instrument meteorological conditions (IMC). It uses the NOAA National Blend of Models to get cloud ceiling forecasts, and joins them with instrument approach data from the FAA's Coded Instrument Flight Procedures (CIFP). With this information, pilots can more easily plan flights to improve their proficiency flying in IMC.
This app uses Google App Engine to host a Node.js server running Next.js. The backend portion of the app is very simple, and just runs a query against a few Google BigQuery tables. Weather forecasts are regularly fetched from NOAA using GitHub Actions and loaded into BigQuery. Similarly, the FAA's CIFP data is periodically fetched by a GitHub Action and loaded into BigQuery.
