Development and Installation Decision

• Standalone versus Integrated – Certification Issues

• Location• Limitations for use

– Cost• Development• Installation

– Time to installation• Critical

ADS-B/TCAS System

• Cockpit Display of Traffic (CDTI)• CDTI control panel• Link Data Processor Unit (LDPU)• TCAS computer• RA/TA VSIs

CDTI

• Correlated TCAS and ADS-B traffic • Multi-function display (MFD) 757/767

– Weather– Terrain – Navigation– Traffic

• Non-traffic information selectable from Captain or FO EFIS

• Range control changes with non-traffic information displayed

Correlated TCAS & ADS-B

• LDPU Processes TCAS display bus output to form one correlated view of both ADS-B & TCAS traffic.

• Correlated TCAS & ADS-B displayed as chevron or bullet.

• TCAS TA/RA, combine data into new symbol

New Symbols and Functionality

Correlated TCAS TA (yellow circle) with ADS-B directional data (pulsing chevron, bullet)

Correlated TCAS RA (red square) with ADS-B directional data (pulsing chevron, bullet)

Correlation Algorithms

• Human Factors Considerations• Target Correlation

– Affect of missed correlation (duplicate target)– Affect of false correlation (missing target)

• Colors– Display Icons– Annunciations

Operational Approval

• Enhanced see and avoid• Enhanced situational awareness• Limitations

– No maneuvers authorized except as allowed by TCAS RA maneuver

Status

• ADS-B benefit study in progress– Co-opted with FAA– Metrics collection– Jumpseat observations– Union and company feedback sites

• ADS-B/TCAS system installed in all domestic aircraft since January 2004.

• Enhanced visual approach in use • Flight crews extremely pleased with

capability

Applications in Development

• Initial phase of CDTI enhanced flight rules (CEFR)– Misnomer– VMC– Maintain airport in sight

• ‘Call Sign’ procedure– Deviation authorized for Louisville ATC– Pilot use– Controller use
