AirNav FBO is a free iPhone app developed by AirNav LLC. It is a useful tool for pilots and aviation enthusiasts as it provides quick access to aviation fuel prices, FBO (Fixed-Base Operator) information, and critical runway details. The app pulls information from the AirNav website, allowing users to store the data on their phone for in-flight use.

With AirNav FBO, users can easily search for aviation fuel prices at various airports, helping them make informed decisions about refueling. The app also provides detailed information about FBOs, including contact details, services offered, and user reviews. This allows pilots to plan their trips more efficiently by finding suitable FBOs along their route.

In addition to fuel prices and FBO information, AirNav FBO also offers critical runway details such as length, surface type, and lighting. This ensures that pilots have up-to-date information about the runways they will be using, enhancing flight safety.

Please note that while AirNav FBO provides valuable information from the AirNav website, it does not include the website in its entirety. However, the app offers a convenient and user-friendly way to access essential aviation information on the go.
