Surveillance System for NextGen 4D Ops - Bottom Line

A Surveillance Service Oriented Architecture (SOA) via SWIM will berequired

Tighter Separation Standards will be required New Tools for the Traffic Management Team (TMT) will be required

Conformance Monitoring Automation

Displays

Surveillance Information - Highly Accurate and Timely from Multi-SensorTrackers with inputs from all types of Surveillance Sensors

Data Links of Aircraft State, Intent, and 4D Trajectories

Real-Time System Certification

GOOD NEWS - ALL REQUIRED ELEMENTS HAVE BEEN

DEMONSTRATED, REQUIREMENTS ANALYSIS CONDUCTED, ANDINITIAL NETWORKING AND INTEGRATION HAS YIELDED POSITIVERESULTS

4D Operations Required Navigation Performance (RNP)

Over Decades the Aviation Community has defined RNP for many flightoperations

Improvements in FMS and the use of GPS, WAAS, LAAS, etc. have enabled

very precise navigation RTCA has documented these requirements Future FMS will contain algorithms to calculate the aircrafts current Actual

Navigation Performance (ANP) DL will be used to transfer this information to TM automation RNP for each 4D Operation must be defined

reduced lateral separation requirements for operations to parallel runways merging and spacing reduced separations time-based ATM more efficient use of terminal airspace through dynamic routings improved surface traffic management

high-density en route corridors oceanic pair-wise maneuvers, and certified sensor monitored airport surface movement

Required Surveillance Performance (RSP) for the 4D OpsRNP

RSP for 3 nmi and 5 nmi separation standards has beenexpressed in an RNP metric of NAC position (see next chart)

Enroute NAC position 5 (RNP-1)

Terminal NAC position 4 (RNP-0.5)

RSP for future reduced separation

Terminal, 2 nmi separation requires a NAC position of 6 (RNP-0.3)

RSP for 4D Ops

Electronically monitored airport surface movement may required a

NAC position of 11 (LAAS, EPU of less than 3m, VEPU of less than4m)
