Advanced ATM Techniques Symposium and Workshops Today s Opportunities for Saving Fuel and Reducing Emissions 4 6 November 2013, ICAO Headquarters, Montréal ATFM Planning and Management Pre-tactical Planning and Collaborative Sub-regional Information sharing 17
Motivation Move from reactive to proactive sub-regional daily ATFM planning 4-stage pre-tactical planning sequence i. ATFM-specific weather briefings and airspace utilization assessment ii. Determination of anticipated Airport Acceptance Rate (AAR) and Capacity Notification message iii. Demand versus Capacity assessment and determination of ATFM measures iv. Distribution of Constraints, Capacities, ATFM measures and Delays via CDM processes 18
Pre-tactical Capacity Determination and sharing of ATFM Daily Plan 19
Pre-tactical Planning Process ATFM-specific weather briefings and airspace use plan Distribution of Constraints, Capacities, ATFM measures and Delays via CDM processes Capacity Assessment Capacity Notification message Demand versus Capacity assessment and determination of ATFM measures 20
