Extent: E+W+S+N.I.

The requirements referred to in regulation 18(i) are that the emissions have—
(i) a maximum mean power spectral density—
(aa) no greater than -41.3 dBm/MHz;
(bb) no greater than -51.3 dBm/MHz –20*log10(10[km]/x[km])(dBm/MHz) (where x is the aircraft height above ground in kilometres) provided that the aircraft that the ultra-wideband equipment is onboard is higher than 1000 meters above ground level; or
(cc) no greater than -71.3 dBm/MHz provided that the aircraft that the ultra-wideband equipment is onboard is at or lower than 1000 meters above ground level but not on ground level; and
(ii) a maximum peak power no greater than 0.0 dBm or the equivalent transmission level.
