Cellular-based Collision Avoidance System
CCAS (pronounced /ciːkæs/; CEE-kas) is an aircraft collision avoidance system, especially used by VFR pilots. CCAS operates in lower airspaces, depending on the terrain from ground level up to 5,000 ft AGL.
How it works
Each CCAS client periodically sends its own position to the CCAS network. On the other hand, the CCAS servers broadcast all relevant traffic around this position back to the CCAS client. By using standard TCP connections combined with a highly optimized protocol, this operates almost in real-time.
Besides other CCAS users, the server also broadcasts traffic information from different other sources, such as ADS-B, as well as OGN/FLARM, in order to have as much information as possible.
How to use
In order to use CCAS and help increase safety in the air, simply download the official CCAS client. It's completely free by the way!
The client is available for Android and iOS (Comming soon) devices.
How to contribute
Simply use the client. Every pilot using CCAS makes an important contribution to make the airspace safe.
