Airborne Separation Assistance System (ASAS)

摘要

Ever since the start of aviation, pilots have dreamed about knowing the positions and intentions of surrounding traffic, as this information is essential to safely conduct their flights. A new affordable technology called ADS-B (Automatic Dependent Surveillance—Broadcast) is now available for civil pilots to enhance the rudimentary Flight Information Services now relayed to them by air traffic controllers. It is possible to discuss forever the pros-and-cons of a top-down approach or a bottom-up approach. Or should the technologies of communication, navigation, and surveillance (CNS) precede the operational procedures of air traffic management (ATM)? There is no single right approach. To avoid dead-ends or failures to act, the solution seems always to be pragmatic and to find a balance between the two approaches.
