Packages of ground surveillance /airborne surveillance applications

• Package I (2005-2011)– Ground surveillance applications– Airborne traffic situational awareness & airborne spacing

• Package 2 (2012-2020)– Enhancements of package I– ADS-B as a sole means of surveillance in high density

airspace– Airborne separation– Airborne self-separation in low-density

• Package 3 (>2020)– Enhancements of previous packages– Airborne self-separation in medium/high-density– …

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

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

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

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

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 surfacemovement services in lowvisibility conditions and at night

• Implementation considerations– No detrimental impact on flight

crew– Could be necessary to equip all

aircraft/vehicles

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

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

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 attaxiway crossings, before enteringa runway, on pushback)

– Reduced taxi time in particular duringlow visibility conditions or at night

• Implementation considerations– Traffic identification needs to be

re-visited– Essential to display all surrounding

relevant traffic

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 reasonfor ATC instructions

• Implementation considerations– Traffic identification needs to

be re-visited– Essential to display all

surrounding relevant traffic (filtering)

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

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
