TRANSCRIPT
Enhanced sequencing and merging operations
• Objective: to redistribute tasks related tosequencing (e.g. in-trail) and merging oftraffic between controllers and flight crews.
• Benefits:– Controller availability by reorganisation
and streamlining of tasks– More regular spacing based on actual
separation minima and thus an increase in capacity– Increased flight crew awareness of traffic and anticipation of
ATC instructions • Implementation considerations
– New instructions will require specific functions on board aircraft related to HMI and automation
– Only pair-wise equipage required but maximum benefits from all equipped

Enhanced sequencing and merging operations – heading then merge
• Controller
– Designates target “XYZ456, select target 1234”
– Gives initial heading, waypoint and desired spacing“XYZ456, heading 270 then behind target merge INKAK 8 miles behind”
• Navigation
– Target direct INKAK (no turning point)
– Ownship on heading then direct INKAK (not on target trail)
• Air-air surveillance
– Target position and speed (no intent required)
• Pilot
– Identifies target“XYZ456, target 1234 identified, 8 o’clock, 30 miles”
– Resumes when spacing obtained then, adjusts speed to maintain spacing

Overall:• Four measured sectors• Dense and “generic” airspace (Paris South-East arrivals)• All traffic equipped• Use of spacing instructions at controller’s discretion
Independent variables:• Level of traffic (high, very high)• Sector configuration (converging point)• Use of airborne spacing (with, without)

CoSpace - Spatial mapping of instructions
In-trail procedure in oceanic airspace
• Objective: to allow in-trail ADS-B equipped aircraft in non-radar oceanic airspace, which may not be longitudinally separated from each other, to climb or descend through each other’s flight levels.
• Benefits:– Improved utilisation of the North Atlantic
oceanic airspace by facilitating a higher
rate of flight level changes yielding better
flight efficiency (e.g. fuel savings,
avoiding turbulent flight levels)
• Implementation considerations– Safety studies needed to determine spacing value

Enhanced crossing and passing operations
• Objective: to provide controller with new set of instructions to solve conflicts e.g. directing flight crews to cross or pass designated traffic aircraft while maintaining a given spacing value.
• Benefits:– Increased controller availability through
reorganisation and streamlining of tasks– Increased flight crew awareness of traffic
and anticipation of ATC instructions
• Implementation considerations– New instructions will require specific
functions on board aircraft related toHMI and automation
– Only pair-wise equipage required butmaximum benefits from all equipped

• Airborne self-separation applications(i.e. PO-ASAS category IV applications)in low-density airspace
‘Package III (>2020)’
• Enhanced ground surveillance / airborne surveillance applications from previous packages
• Airborne self-separation applications (i.e. PO-ASAS category IV applications) in
medium/high-density
airspace

Average route length ~5% longer than direct
