OverviewOverview

Key ATM improvement applications? apps serving capacity, punctuality

Which aircraft to consider? What makes up for the current ATM situation Some current in-service aircraft statistics

• quantities, make, type• the relative influx of new aircraft

To what extent can these aircraft accept change end-end application, analyze layers of the stack

Discussion apps, required mods, issues and questions; apparent limitations

Conclusion and recommendation required focus, technical issues, degree of achievable improvement


Key ATM improvement applicationsKey ATM improvement applications

Airline value will be in capacity and punctuality improvement Ability for more movements Each movement closer to plan

The application benefit should be “direct” to the investing airline To improve chances of returning any investment

AcronymAirborne Surveillance Applications (pack 1)

Enhanced crossing and passing operations

In-trail procedure in oceanic airspace

Enhanced sequencing and merging operations

Enhanced successive visual approaches

Enhanced visual acquisition for see & avoid

Enhanced traffic situational awareness during flight operations

Enhanced traffic situational awareness on the airport surface

ADS-out and ADS-inADS-out and ADS-in

Awareness functions broadcast current state vector and trajectory data for others to use

Enhanced vision functions broadcast current state vector for others to receive and derive acquisition cues

Track oriented functions broadcast trajectory data for others to perform CD&R, S&M, in-trail following

Any new flight crew responsibilities? Consider procedures, training, liability Consider convergence, integrity

• Does each have the same judgment?• Need for coordination? (re ACAS)

….. to support change….. to support change

All applications require “cooperative” aircraft Single aircraft equipage will not produce the application ADS-B “in” and “out” required

For the next 10 years existing fleet largely dominates European ATM operations New deliveries gain relative importance after 2015

Conclusion retrofit requirement However, EFIS, FMS changes? Datalink: ADS-B in/out required “Intermediate” and “top” layers of the stack required

• Surveillance processing / Applications• Man machine interface

Conclusion and recommendationConclusion and recommendation

Required focus ATM improvement aircraft focus retrofit By far largest factor on improvement

• For many years to come Technical

ADS “in” and “out”, required for any application Man - machine interface (flight crew interactions) End systems (FMS interactions) Applications development

Degree of achievable improvement Limited to relatively small procedural change

• Limited responsibility delegation to flight crew– Airline Liability question– Technical “convergence” issue

Investment dilemma Airline motivation to invest largely depends on return certainty Requires: Direct and unconditional benefit
