Small and medium-sized airports need cost-efficient solutions to perform operations in low-visibility conditions. While advanced equipment (e.g. A-SMGCS) and services are widely available, the cost of installation and maintenance may exceed the financial capability of secondary airports. Introducing low-cost solutions can bring direct benefits, and lead to increased capacity at primary airports by reducing the number of flight deviations. SESAR addresses both the ground and airborne aspects.

From the ground perspective, the candidate solution evaluates different options for aircraft and vehicle tracking using camera-based systems as an affordable alternative surveillance source, or in combination with other available surveillance sources such as multilateration and automatic dependent surveillance – broadcast (ADS-B) sensors. All airport stakeholders can use the video data as a tool to enhance safety and operational performance.

From the airborne perspective, the candidate solution aims to evaluate ATC requirements for precision approach procedures with vertical guidance down to Category II decision height, or no lower than 100 ft (60 m). This relies on satellite signals from GNSS (such as Galileo), either with use of satellite-based augmentation (SBAS) or ground-based augmentation (GBAS). The airborne perspective considers on-board equipment support to landing onto secondary airport. The candidate solution is assessing if a single GBAS ground station can enable approach operations during low visibility conditions without other significant infrastructure.
