2 2 Federal Aviation Administration NextGen High Density Airports Theme Table of Contents The Team Executive Summary – What is 3D PAM Project Status Detailed Description of the Concept High Level Schedule

3 3 Federal Aviation Administration NextGen High Density Airports Theme Team Members NextGen Transportation System Joint Planning and Development Office

4 4 Federal Aviation Administration NextGen High Density Airports Theme 3D PAM – FAA, NASA and Industry Leads for Coordination: –Marc Buntin - Project Lead –Richard Coppenbarger - EDA Principal Investigator –Ewald Schoemig – FD Concept Lead, FD HITL Sims –Doug Sweet - EDA SW development

5 5 Federal Aviation Administration NextGen High Density Airports Theme Executive Summary (The Problem) Significant congestion exists today in the arrival and departures streams of medium to large airports Air Traffic Controllers frequently sequence traffic –Diminishes capacity and efficiency –Problem will not improve without intervention 3D Path Arrival Management operational concept is an initial intervention in advance of NextGen 4D trajectory operations to address this problem.

6 6 Federal Aviation Administration NextGen High Density Airports Theme Executive Summary (The solution – 3D PAM) Efficient and predictable method to deliver aircraft from the TOD to a metering fix: –Requires: New automation support tool (TMA enhancement) and modern FMS Allows the aircraft to fly an efficient, optimized descent arrival trajectory from cruise to meter fix The automation provides the clearance for the ATC to send to an aircraft –Clearance issued via voice (Future: domestic datalink) Clearance is manually loaded into the FMS for execution –The FMS executes the clearance taking advantage of RNAV / RNP capabilities

7 7 Federal Aviation Administration NextGen High Density Airports Theme 3D PAM Concept Definition Efficient and predictable method to deliver aircraft from the TOD to a metering fix in medium/high traffic demand: New automation support tool (TMA enhancement) and Modern FMS Ground automation provides conflict-free, trajectory-based clearance advisories to ATC –Clearance issued via voice (Future: domestic datalink) Trajectory-based clearances are FMS executed in the airplane: –Utilization of existing aircraft navigation capabilities (LNAV, VNAV, RNP) 3D Path Arrival Management concept is an initial intervention to 4D Trajectory Based Operations, providing efficiency benefits in today’s operational environment

8 8 Federal Aviation Administration NextGen High Density Airports Theme Primary Expected Benefits Improved flight efficiency: –Reliable / Efficient routing –Optimum speed and altitude profiles –Reduced fuel burn, emissions and environmental impact Operational efficiency improvements: –Improved meter fix delivery accuracies –Delay reduction –Reduced frequency and duration of voice communications Increase controller productivity –Reduced workload from trajectory clearances Increased flight path predictability and repeatability –Flight path execution with airplane navigation accuracies –Improved air/ground situational awareness

9 9 Federal Aviation Administration NextGen High Density Airports Theme Required Navigation Performance (RNAV/RNP) and 3D Path Operations Operational Environment – Arrival Transition: –Path stretching is required when speed control is insufficient to achieve spacing –ATC uses automation tools to select conflict free path and speed to space traffic –Voice based clearances for all aircraft –FMS execution of cleared flight paths 3D Path Design: –Lateral path design enables FMS-based execution with LNAV, not heading commands RNP En-route: “Place/Bearing/Distance” or lateral offsets Arrival transition: “Place/Bearing/Distance” (PBD) Terminal Area: Pre-defined 3D paths, published and available in air and on ground –Vertical flight path enables VNAV execution by the aircraft: FMS optimizes the vertical profile: Continuous Descent Arrivals (CDA) in high traffic conditions

15 15 Federal Aviation Administration NextGen High Density Airports Theme 3D PAM – Clearance and Aircraft Types Strategic 3D Path clearances: –Issued after TMA freeze horizon and before TOD –Path stretch based on Place-Bearing Distance (PBD) –Conflict free EDA type advisories consist of new cruise/descent speeds, lateral path stretch, and intermediate altitude (for conflicts only ) Tactical 3D Path clearances – issued if required: –Strategic clearance could not be implemented –EDA time-based monitoring: Meter fix ETA out of compliance –Combined speed and path stretch advisory based on PBD Considered Aircraft Types: Equipage Level Capability 3D PBD capable, LNAV, VNAV and FMC/CDU based cruise/descent speed change 2D PBD capable; Only LNAV Non-equipped No PBD capability, No LNAV, VNAV capabilities
