FAA System Scope
Program funds enhancements required to perform data communications in:
Ground User Interface (e.g. ERAM/DSR display software)
Ground Data Processing (e.g. application software to create clearances)
Ground Data Delivery (e.g. wide area networking between ground facilities)
Ground components of A/G Message Delivery (e.g. radio, ground antenna)
User System Scope
Users fund enhancements required to perform data communications in:
Airborne components of A/G Message Delivery (e.g. aircraft radio, antenna)
Airborne Message Delivery (e.g. aircraft networking)
Airborne Data Processing (e.g. app s/w in comm & flight management units)
Airborne User Interface (e.g. cockpit displays & s/w) 11
