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.

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
