35. Scenarios • EPP Downlink and Consistency check • Early ending Military Activity • Cracked Windshield • Turbulence – Level Change request • Temporary clearance for separation • Heavy wind – Time deviation • Change of STAR • Hotspot resolution by NM

36. Principles • FDMP/FDCs/FDUs roles • EPP data used by ATC/Airport to: • Check consistency • Improve ground-held view • Order of accuracy – update rate (H to L) • Trajectory in C-ATSU (tracks) • IOP Flight Script • Agreed T

45. Early availibility Mil Area in D-ATSU Events • Re-routeing proposal prepared by FDC • FDC notices his proposal is outside RBT tolerances • Through FDMP, FDC starts CDM revision on agreed RBT • FOC and NM are triggered • All partners agree • FDMP puts revised RBT in the Flight Object • EPP Consistency set to FALSE • FDMP updates the Flight Script (and Shared 4D Traj) • FDC detects mismatch Agreed-Cleared RBT and flags to ATCO • ATCO uses DSC • C-ATCO uses Route-Clearance • ATCO waits till flight on frequency (Cleared RBT = kept for PLOC) • EPP is downloaded • Cleared RBT updated by FDMP • EPP Consistency Check like in previous scenario (leading to properly better timing)

46. To be tackled • Where is the Executed Trajectory? • How embed the ARR-Gate to Dep-Gate data? (ATV Hooks) • Develop other scenarios supporting the 4 different processes. • Which EFPL Data fits well / where in FO Structures?

47. Processes • Air Ground Update Process • Air Ground Revision Process • Ground Ground Update Process • Ground Ground Revision Process

48. For Info: Correction Loops • Loop1: • Warning to Pilot: stay within tolerances please • Alert to Pilot: respect constraints!!! • Loop2: • Warning to ATCO: try to respect tolerances please • Alert to ATCO: respect constraints!!! • Loop3: • Warning to NM: OK to breach tolerances? • Alert to NM: Find solution for non-respected constraints
