supports digital route amendments, automated routing, and two-way communication between controllers and flight crews. General Aviation also provides Ground Area Movement Awareness, a surface surveillance and control system that fuses ADS-B, optional surface movement radar, and vehicle-mounted devices. GAMA gives controllers a unified view of airport surface traffic and enables digital clearances, hold-short commands, and runway interlocks. These systems are intended for aviation authorities, airports, and operators seeking to modernize communication, improve safety, and reduce ground infrastructure requirements.
