Shaping Boeing Surveillance Strategy Drivers & Obstacles ASAS Thematic Network II

1.Surveillance standards need revision and extension – Under way 2.Existing ADS-B-Out Equipment has limited potential for operational use – Significant implementation 3.Surveillance enhancements must be driven by comprehensive operational benefits – No change and business case for most is still unclear 4.Single ADS-B link for traffic surveillance of all airplanes is optimal – Still an issue 5.We need a transition strategy for surveillance including operational incentives, mandates, etc. – Still true, but strategies emerging Top Surveillance Issues

Shaping Boeing Surveillance Strategy Overriding principles: Safety comes first Good business case –For customer –For Boeing In keeping with evolving Operational Concepts Consistent with Flight Operations Philosophy –Pilot role –Human Factors Common solution for forward fit and retrofit –Training burden –Cost control

Shaping Boeing Surveillance Strategy Safety –Safety benefits seen in Alaska –Increasing concern about runway incursions CDTI offers a way to part of the solution –Need to continue to maintain and enhance the level of safety Traffic situational awareness can help

Shaping Boeing Surveillance Strategy Customer demand –Increasing interest from operators –Pioneers showing the way UPS, CASCADE, Australia –Increasing numbers of aircraft with ADS-B-out –Discriminator in sales campaigns But… –Is there an operator business case beyond mandates? –When will there be a clear business case? One that is acceptable to operators

Shaping Boeing Surveillance Strategy Availability of benefits –Early use of current ADS-B-out for NRA Europe, Australia, Canada, USA –Added incentives in Australia –UPS –NUP2+ Green Arrivals But… –Benefits expected from ASAS in SESAR and NextGen are still not clear –Competing operations’ being assessed

Shaping Boeing Surveillance Strategy Mandates –Enabling the benefits –Many making use of current equipage Significant numbers in service in some areas –Reducing the developmental cost risk factor But… –Significant span in dates –Some divergence in requirements –Some will not satisfy downstream requirements –Uncertainty over availability of benefits –Current equipment requires recertification To remove limitations on use

Shaping Boeing Surveillance Strategy Evolving Standards and OpCons –Better data on which to base implementation –Eroding risk by making requirements clearer –Early standards cater for use of existing ADS-B-out But… –Mandates being issued before most requirements known –Adds to risk of need for upgrades downstream –Operators do not want to equip twice –For some operational enhancements, new rules will be needed Will they be available when required?

Shaping Boeing Surveillance Strategy Boeing Electronic Flight Bag –Offers a control/display medium for ASAS Aircraft with less capable glass Earlier implementation possibility

Shaping Boeing Surveillance Strategy TCAS –ADS-B data could enhance TCAS –Ultimately, functions using ADS-B-in could eliminate need for TCAS But… –Acceptability of not keeping TCAS independent is unclear –While TCAS remains, potential for divergence in integration with CDTI

Shaping Boeing Surveillance Strategy What about the imponderables? ASAS represents significant change; how acceptable will procedures be? –To pilots –To controllers Will ATSPs accommodate ASAS procedures? –Will ground system equipage keep up or will it limit operator acceptance? What about liability for separation assurance responsibility –Operators –Crews –Manufacturers Can traffic demand represented by VLJs, UAVs, etc. be satisfied with ASAS technology and procedures?

Conclusions There are still many unknowns –What is technically relatively simple is much more complex in several other dimensions We have come a long way together But we have at least as far to go before the outcome is clear We plan to be in the game when that outcome is realized…
