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


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


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


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


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


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?


Boeing Electronic Flight Bag– Offers a control/display medium for ASAS

• Aircraft with less capable glass• Earlier implementation possibility


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


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…
