Ensuring improvements to air transport safety


The International Civil Aviation Organization (ICAO) is currently defining a Global Aeronautical Distress and Safety System (GADSS). Its object is to secure precise and updated location of an aircraft as soon as possible once abnormal aircraft behaviour is detected.
All-weather landing capacity is also central to ensuring flight regularity in safety. Existing systems require ground infrastructure only available in some large airports, but in future onboard systems (Enhanced Flight Vision System/EFVS) could be of assistance for landing on smaller airfields. One solution would involve millimetre wave radar in the 31.8-33.4 GHz band operating in the radionavigation service.
For all of these requirements, global spectrum harmonisation is vitally important.

Proposal 1

ANFR will follow ICAO’s work on the GADSS concept of operations and will cooperate with the French Directorate General for Civil Aviation (DGAC) to determine how best to respond to spectrum requirements for GADSS development.

Proposal 2

After supporting EFVS recognition in ITU-R, the Agency will make a contribution to 5G compatibility studies in the 31.4-33.8 GHz to ensure EFVS protection at global level.
