[31] When the level of the transition altitude is lower than 3 050 m (10 000 ft) AMSL, FL 100 should be used in lieu of 10 000 ft. Competent authority may also exempt aircraft types, which for technical or safety reasons, cannot maintain this speed.
[32] Pilots shall maintain continuous air-ground voice communication watch and establish two-way communication, as necessary, on the appropriate communication channel in RMZ.
[33] Air-ground voice communications mandatory for flights participating in the advisory service. Pilots shall maintain continuous air-ground voice communication watch and establish two-way communication, as necessary, on the appropriate communication channel in RMZ.
EASA's Standardised European Rules of the Air (SERA) define airspace classes (A-G) dictating air traffic control services, separation, and communication requirements for IFR and VFR flights. Higher classes offer comprehensive ATC, while lower classes provide advisory services. Speed limits apply below 10,000ft, and radio communication is often mandatory.
