FAA Surface Indicating & Alerting Program (SURF IA)

• FAA Sponsored Program with Honeywell, Jet Blue & Alaska AirlinesFAA Sponsored Program with Honeywell, Jet Blue & Alaska Airlines• Sixteen Month Program (Nov 2008 - Mar 2010) to:

- Accelerate RTCA SURF IA standards development by producing an Operational Performance Assessment and Operational Safety Assessment

- Develop display concepts and indication and alerting algorithms Honeywell human factors evaluation included JetBlue Airways and Alaska Airlines pilots

- Prototype display, surveillance and alerting functionality- Demonstrate the system Demonstrations at Seattle-Tacoma International airport (SEA) and Snohomish County Paine

Principal Findings

Pilot Acceptance:• Pilot Acceptance:- Generally good Pilot Acceptance- Pilots found airport map and traffic display very useful for gaining and

maintaining situational awarenessmaintaining situational awareness- Display of “Engaged Traffic” and “Target Velocity Vector” was very

useful- Pilots prefer ASSA display, but found FAROA acceptable- No data to support a requirement for inhibiting indications and alerts

during Land and Hold Short Operations (LAHSO)• System Performance Observations:

O ll t f d ll ith b ti /li it ti- Overall system performed well with some observations/limitations:- Some concerns/limitations observed with ADS-B data:

Navigation Integrity Code (NIC) and Navigation Accuracy Code for Position (NACp) values reported by aircraft were often outside the limits set for SURF IA

M ADS B i d i ft d t h H di tl t d- Many ADS-B equipped aircraft do not have Heading correctly reported (generally use Track angle, which is reported as zero when aircraft is stationary)

- ADS-B transmissions were sometimes masked when line-of-sight was


gblocked

- Occasionally observed loss of ADS-B signal reception, possibly due to multi-path reflections from hangars and/or large aircraft

ADS-B In Trail Procedure Operational Evaluation

• Honeywell has developed, integrated, and certified a complete ITP avionics capability STC’d on United Airlines 747-400s.

• The system consists of our TPA-100B Traffic Computer with ADS-B In and ITP capability TRA 67A Transponders with ADS-B Out and a GoodrichITP capability, TRA 67A Transponders with ADS B Out, and a Goodrich Class 3 SmartDisplay® EFB running Honeywell SmartTraffic™ ITP display software.

What About UAT?+ Additional “uplink” capacity - ATC Transponder still requiredAdditional uplink capacity + Supported in U.S.+ ADS-B Out and In+ Lower total cost?

ATC Transponder still required- Support for TCAS, SSRs

- Common control inputs - Mode A codes Ident+ Lower total cost?

+ lower transmit power + integral receiver+ design analysis on going

Mode A codes, Ident- Global standard is 1090ES

- Not globally interoperable- Need for rebroadcast+ design analysis on-going Need for rebroadcast

- Requires “timemark” from GPS

Conclusion

H ll i itt d t ti ADS B l b ll• Honeywell is committed to supporting ADS-B globally- Hundreds of ADS-B transponders delivered- More research & development underway

H l i t d l th l b l t d d f ADS B- Helping to develop the global standards for ADS-B- Aircraft equipage decisions required for older aircraft

Performance Based Req irements• Performance-Based Requirements- Exploit DO260 equipage for early applications- Align position performance and operational requirements

• ADS-B is a relatively simple technology - Varying business cases for operators and ANSPs

Pl t d li l t ll t k h ld th h t th t iti- Plans must deliver value to all stakeholders throughout the transition- This will accelerate aircraft user adoption and airspace benefits- ADS-B In system complexity still in work with Merging and CDTI
