UPS ADS-B/TCAS B-757/767 Installation ASAS Thematic Network Third Workshop April 19,2004 Captain Jim Walton United Parcel Service Advanced Flight Department
Overview Fleet Status Development and Installation Decision ADS-B/TCAS System Operational Approvals Status Applications in Development
Fleet Status 32 B-767—100% 73 B-757—97% 11 A —1090 Squit Only
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
LDPU TCAS RA IVSI CDTI RA IVSI RA/TA bus ADS-B/TCAS Architecture
Architecture Showing LDPU Failure LDPU TCAS RA IVSI CDTI RA IVSI RA/TA bus Independent buses
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 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
