Requirements for communications, SSR transponder and electronic conspicuity in
U-space airspace
Regulation
(EU) 2021/666 (EU) 2021/666
(a) Radio mandatory zone (RMZ)
(1) VFR flights operating in parts of Classes E, F or G airspace and IFR flights operating in parts of Classes F or G airspace designated as a radio mandatory zone (RMZ) by the competent authority shall maintain continuous air-ground voice communication watch and establish two-way communication, as necessary, on the appropriate communication channel, unless in compliance with alternative provisions prescribed for that particular airspace by the ANSP.
(2) Before entering a radio mandatory zone, an initial call containing the designation of the station being called, call sign, type of aircraft, position, level, the intentions of the flight and other information as prescribed by the competent authority, shall be made by pilots on the appropriate communication channel.
(b) Transponder mandatory zone (TMZ)
All flights operating in airspace designated by the competent authority as a transponder mandatory zone (TMZ) shall carry and operate SSR transponders capable of operating on Modes A and C or on Mode S, unless in compliance with alternative provisions prescribed for that particular airspace by the ANSP.
(c) U-space airspace
Manned aircraft operating in airspace designated by the competent authority as a U-space airspace, and not provided with an air traffic control service by the ANSP, shall continuously make themselves electronically conspicuous to the U-space service providers.
(d) Airspaces designated as radio mandatory zone, transponder mandatory zone or U-space airspace shall be duly promulgated in the aeronautical information publications.
European aviation rules mandate radio communication in designated zones (RMZ) for specific flights. Transponders are required in transponder mandatory zones (TMZ). In U-space airspace, manned aircraft without air traffic control must be electronically conspicuous. These airspace designations are published in aeronautical information.
