Hi friends ,

Benefits of ADS-B
ADS-B is intended to increase safety and efficiency. Safety benefits include:[5]
* Improved visual acquisition especially for general aviation under visual flight rules (VFR).
* Reduced runway incursions on the ground.
ADS-B enables increased capacity and efficiency by supporting:
* Enhanced visual approaches
* Closely spaced parallel approaches
* Reduced spacing on final approach
* Reduced aircraft separations
* Enhanced operations in high altitude airspace for the incremental evolution of the "free flight" concept
* Surface operations in lower visibility conditions
* Near visual meteorological conditions (VMC) capacities throughout the airspace in most/all weather conditions
* Improved ATC services in non-radar airspace
However, although ADS-B is suitable for surveillance of remote areas where the siting of radars is difficult, some ATC providers are not yet convinced that it is currently suitable for use in high traffic volume areas, such as in UK and Northern European airspace. Changing from conventional SSR to ADS-B would also require investment in ATC infrastructure, something which many European providers may be unwilling to sanction. Furthermore, ADS-B provides no ground verification of the accuracy of the information provided by aircraft and this could have adverse security implications.[6]
