for the FANS 1/A technology with the Continental SPR Standard
(DO-290) to include interoperability for interface with HF 
Data Link (HFDL). The document, initially issued in September
2000, defines interoperability requirements for communication
services and Air Traffic Services (ATS) appli¬cations and
allocates these requirements to stakeholders. It covers: the
ATS Facilities Notification (ATN) application, the Automatic
Dependent Surveillance (ADS) application, the Controller Pilot
Data Link Communication (CPDLC) application and the ARINC data
communication.
