FASST-CH Analysis
In 2024, FASST-CH analysed and assessed services and technologies enabling electronic visibility (e-conspicuity) in the airspace.
A survey of general aviation revealed that, in Switzerland, numerous non-certified systems (e.g. PowerFLARM) are in use alongside transponders.. The Swiss aviation community demonstrates a proactive approach to e-conspicuity, through “do-it-yourself” ground-based infrastructure of receive antennas.
FASST-CH concluded that an e-conspicuity mandate is feasible and beneficial for both manned and unmanned flights. In specific parts of the airspace and certain user groups can be allowed to comply to the mandate thanks to alternative solutions to transponder.
Recommendations of the Swiss Transportation Safety Investigation Board (STSB), the requests from the general aviation for a better access to airspace, complex drone operation requirements as well as AVISTRAT strategy all concur to FASST-CH conclusions.
