Operations by ADS-B


IntroductionIntroduction – General Aviation – General AviationIntroductionIntroduction – General Aviation – General Aviation

The general Aviation community, if considered to be mainly non commercial operations, is sometimes the one’s that need technical improvements and additional tools for their continued presences in the more and more regulated airspace of Europe the most.

However, the costs attached to the various technologies developed for large commercial operations can hardly ever be justified.

Overshadowed by commercial industryGA requirements need to be addressed

Identified requirementsIdentified requirementsIdentified requirementsIdentified requirements

Continued/ improved presence of GA in controlled airspace – co-existence with larger commercial A/C

No use of safety-critical ASAS applications in cockpit for GA acceptable

“ADS-B out “ only - unless for information GA not the driver in Europe…? Min cost of equipment important Minimum power important Replacement of ELT Avoidance of SSR Transponder for certain categories of aircraft

like gliders Mandatory air/ ground data link equipage not questionable for GA

SummarySummarySummarySummary

VHF Multi mode radio concept available Potential synergies for the GA market identifed GA organisations involved in the development Concept needs to be discussed in a wider forum Need to involve various programmes in Europe

focusing on the individual elements of C,N and S. Validation and test environment available Certification and safety issue needs to be further

analysed Business case needed to verify the potential benefits.

Enhanced Operations for General Aviation –EGOA

50 General Aviation A/C in dense TMA operations with focus on surveillance improvements with embedded navigation and communications elements.

Combined use of voice com and data com Aircraft types ranging from gliders to twin engine Can be expanded to adress 8.33, and GNSS/ EGNOS

use. Trials period Q1 2004 –Q1 2005.


The EGOA project

SCAA project Flying Clubs / Pilots Air Traffic Controllers Industry


ObjectivesTo demonstrate and evaluate ADS-B for general aviation and other non-commercial aircraft including military

Following aspects will be considered:- improved safety- improved efficiency for ATC- enhanced service to the users- enhanced availability to controlled airspace


Goals

General aviation requirements in focus Evaluation testbed, technique and

operations Information, acceptance and education to

relevant organisations and partners.


Goals…

Co-ordination with military sector Preparation for certification/operational approval


How?

Through large scale operative trials/ demonstrations in Östgöta TMA, where numerous types of aircraft are involved, the operational scenarios will be presented and evaluated


How…

• Combined voice/ADS-B transonder

• Presentation units integrated with ADS-B functionalities will be used – air/ground

• Usage of approved standards and protocol

• Development of rules and methods

• Preparation for operational approval will be a parallel activity, FHA…

Step III Weather Applications (FIS-B) VDLM4-Equipment for weather service Upgrade of CDTI with weather interface Development of weather server (prototype), operating with real

weather information, METAR… ATGround/Air Focus Identification of appropriate

scenarios, for trial activity Report/Evaluation

-Pilot/Controller/Technical Expertise


Operative gains Safety

– Possibility to monitor ADS-B equipped a/c at own airport

– Possibility to monitor ADS-B equipped a/c at neighbour airport

– Positive identifying of airborne a/c, when equipped– Reduced risk for prohibited flying in controlled

airspace Relations/goodwill

– Good relations to users , who will get access to controlled airspace thanks to ADS-B equipment

Workload– Reduced workload for ATC
