If a notice given by the CAA to a licence holder so provides, such air traffic services as are specified in the notice are to be treated as not being authorised services for the purposes of section 8 in its application to that holder.

A notice under subsection (1) may specify the air traffic services by reference to part of a licensed area.

A notice under this section may be modified or revoked by a further notice given by the CAA to the holder concerned.
