ABSTRACT
The very high-frequency digital link (VDL) is an air-ground subnetwork that may be applied in supporting data communication across aeronautical telecommunication network (ATN) aircraft-based application processes and the peer ground-based processes. Presently, the VDL has been recommended as the major method of air traffic management (ATM) in the transition to the future ATN and has been deployed in many areas such as central Europe and North America.
