What is the maximum effective radiated power (e.r.p) allowed for radio outputs?

The maximum effective radiated power (e.r.p) for radio communications is critical for ensuring proper communication while minimizing interference with other services. For the class of radio communication under the Restricted Operator Certificate - Aeronautical, the standard limit for e.r.p is capped at 250 watts. This limit is established to maintain a balance between effective communication range and the prevention of excessive interference, which could affect not only other radio communications but also navigational aids and safety operations. Adhering to this limit ensures that operations remain compliant with regulations while providing effective communication capabilities in aeronautical environments.
