Malmö 5 September. 27 th 2005 NUP ITP A three day simulation december 2004  Day 1: base line scenario  Day 2: ITP, all aircraft equipped  Day 3: ITP, 80% equipped

Malmö 5 September. 27 th 2005 NUP ITP Traffic: real traffic from december NAT tracks, A, B and C No crossing traffic Time of entering the airspace: »From 11:30 to 18:00 Number of aircraft per track: »A: 9 »B: 49 »C: 45

Malmö 5 September. 27 th 2005 NUP ITP Participants: 4 controllers »1 female, 3 males »Age: 28 – 38 »ATC experience: 2 – 8 years 2 pilots »Requesting clearances and accepting messages.

Malmö 5 September. 27 th 2005 NUP ITP The process: Pilots asked for FL changes, both standard and ITP requests The controller accepted or rejected the request If clearance was issued the pilot would accept through CPDLC if ITP or via voice if standard clearance. For ITP clearances, regular level reports throuch ADS-C

Malmö 5 September. 27 th 2005 NUP ITP Reykjavik SPACING In Trail Climb Reykjavik ITP »HMI design and mockup evaluation »Early safety considerations Concept : The aircraft is responsible for ensuring spacing with designated traffic => Spacing application

Malmö 5 September. 27 th 2005 NUP ITP Spacing In Trail Climb HMI

Malmö 5 September. 27 th 2005 NUP ITP Spacing In Trail Climb : Conclusions Results : »Automatic altitude changes rejected »Pilot manual action on FCU is preferred (safety aspects) »Phase of flight not heavy »Computation by FMS of point of crossing with Flight Level »Would require significant FMS change »Time opportunity window considered useful »Requires significant FMS change »Alerts needed when spacing infringed Significant changes required not justified by Spacing ITC alone Airbus push for In Trail Procedures based on ATSAW ATSA-ITP developed at RFG

Malmö 5 September. 27 th 2005 NUP ITP NUP – 2, ITP Conclusions ITP »Simulation shows acceptable by controllers Spacing Application »Historical reasons for selecting »Stepping stone into level 3 application »No specific separation change required »Spacing role not realistic »80% equipage - > acceptable nuisance

Malmö 5 September. 27 th 2005 NUP ITP NUP – 2, ITP Conclusions RFG Level 0,5 & 1,5 Application »Logical simplification of the NUP ITP »Passing safety case ITP not sole means of solving problem »30 / 30 affects (RVSM results) »CPDLC usage already enabling an increase in actual climbs
