3. Package I of ground surveillance / airborne surveillance applications
Ground surveillance applications
ATC surveillance for enroute airspace
ATC surveillance in terminal areas
ATC surveillance in non-radar areas
Airport surface surveillance
Aircraft derived data for ground tools
Airborne surveillance applications
4 airborne traffic situational awareness applications
3 airborne spacing applications

4. ATC surveillance for en-route airspace
Objective: to enhance ATC surveillance currently provided with radars e.g.surveillance areas where single radar coverage provided.
Benefits:
More accurate position and track prediction (accuracy does not vary with range and bearing)
Back-up for radar system
Implementation considerations
No detrimental impact on flight
crew
Large network of ground ADS-B
receivers
Start en-route phased
development in low-density

5. ATC surveillance for terminal areas
Objective: to enhance ATC surveillance currently provided with radars e.g. surveillance at low altitude and close to terrain and also in areas of single radar coverage.
Benefits:
More accurate position and track prediction (accuracy does not vary with range and bearing)
Back-up for radar system
Implementation considerations
No detrimental impact on flight crew
Network of ground ADS-B stations
in TMA

6. ATC surveillance in non-radar areas
Objective: to provide ATC surveillance in non-radar areas e.g. remote areas, offshore, operation areas, any continental areas and certain oceanic areas, which, due to traffic level or cost of equipment could not justify installation of radars.
Benefits:
Surveillance with accurate position and track prediction (accuracy does not vary with range and bearing)
Controller can provide radar-like separation services instead of procedural
Implementation considerations
No detrimental impact on flight crew
Large network of ground ADS-B
receivers

7. Airport surface surveillance
Objective: to provide new source of surveillance information for ground movement management at airports with or without Surface Movement Guidance Control System. Airport ground vehicles can also be fitted with the necessary equipment and displayed on an airport map together with aircraft
Benefits:
Controllers can provide safer
and more efficient surface
movement services in low
visibility conditions and at night
Implementation considerations
No detrimental impact on flight
crew
Could be necessary to equip all
aircraft/vehicles

8. Aircraft derived data for ground tools
Objective: to provide additional aircraft derived data through ADS-B for ground applications e.g. ATC displays, conflict detection tools, arrival and departure management tools, ground based safety nets and collaborative decision making applications
Benefits:
ATC has feedback on such parameters as autopilot selected heading, altitude, and flight management system next waypoints
Implementation considerations
No detrimental impact on flight crew
Harmonisation with other data-link to facilitate integration on-board aircraft e.g. Mode S, ADS-C
ADS-B Receiver ground-station

9. Package I of ground surveillance / airborne surveillance applications
Ground surveillance applications
5 applications
Airborne surveillance applications
Airborne traffic situational awareness
Enhanced traffic situational awareness on the airport surface
Enhanced traffic situational awareness during flight operations
Enhanced visual acquisition for see & avoid
Enhanced visual separation on approach
Airborne spacing
3 applications

10. Enhanced traffic situational awareness on the airport surface
Objective: to provide flight crew with an enhanced traffic situational awareness on the airport surface for both taxi and runway operations in all weather conditions
Benefits:
Flight crew can more easily detect
unsafe conditions e.g. conflicts at
taxiway crossings, before entering
a runway, on pushback)
Reduced taxi time in particular during
low visibility conditions or at night
Implementation considerations
Traffic identification needs to be
re-visited
Essential to display all surrounding
relevant traffic

11. Enhanced traffic situational awareness during flight operations
Objective: to provide flight crew with an enhanced traffic situational awareness irrespective of visual conditions
Benefits:
Flight crews more able to
detect unsafe conditions
Better flight crew anticipation
and understanding reason
for ATC instructions
Implementation considerations
Traffic identification needs to
be re-visited
Essential to display all
surrounding relevant traffic (filtering)

12. Enhanced visual acquisition for see & avoid
Objective: to aid flight crews perform collision avoidance task when separation service not provided by ATC e.g. IFR/VFR in class D and E airspace, class G airspace
Benefits:
Flight crews better able to detect aircraft in blind spots
Improved safety of general aviation or helicopter operations
Implementation considerations
Benefits proportional to number of aircraft equipped

13. Enhanced visual separation on approach
Objective: to aid flight crews perform successive visual approaches when they are responsible for maintaining visual separation from the aircraft they are following
Benefits:
Aid to visually acquiring and re-acquiring target
Flight crew can efficiently cross-check visually acquired target information e.g. range
Perform successive visual approaches on a more regular basis
Implementation considerations
Only pair-wise equipage required but maximum benefits from all equipped
