10 The challenges of today's ATM Punctuality and schedule integrityMaximum use of existing capacity in all weather operationsCost of unstable operationsInstitutional and behaviour changesMaintaining or increasing current safety level
11 Key enablers for the future ATM Repetive routine control/planning tasks performed with limited automationsolution : CPDLC + air/ground communication + better ground systems automationSystems performance sharing : planning and flow capacity determination based on updated 4D flight plan exchanged between aircraft, airline, ATC, ATS planning; flights based on agreed trajectory; arrival time : "on time, first serve"solution : air/ground system integration + ground/ground coordination + 4D trajectory controlSaturation of dense airspace, mediocre visibility, reduced landing rates, stabilisation of arrival based on improved landing systemssolution : some delegation to pilots (enhanced visual acquisition, cluster control, station keeping), better runway/taxiway situation awareness, procedure/behaviour/instituational changessolution : GLS, MLS

27 The challenges of ADS-B and ASAS Services are still being worked: definition, operational concept, etc. Use of basic aircraft parameters on the ground have been discussed for years; still no implementation!HMI : merge of TCAS and ADS-B information, clutter of information, representation of many parameters (state, intent, etc)SafetyDefinition of an architecture requires establishment of needs/performance/safety requirements leading to a safety analysis : new methodology to address air/air communication environmentExisiting aircraft system will need significant improvement and may require upgrade of criticality level e.g.calculation of position becomes criticalstation keeping requires control loops with autopilot/flight controlsDelegation of responsibility : institutional issues, human issues, cockpit operations
