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
B-767 Flight Test Video
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
