2.2.6

From the instructions and information provided by the FISO to aircraft on the
appropriate areas of the aerodrome, the pilot will be able to determine if it is safe to
taxi. From the information provided by the FISO, the pilot will determine if it is safe to
land, take-off or transit the ATZ. FISOs are not permitted to refuse entry into the ATZ
when requested by a pilot. The aerodrome authority may decide that they will not
permit an aircraft to land at their aerodrome and request that the FISO pass this
message on. Such a message must be prefixed: ‘Message from the aerodrome
authority...’ FISOs may

not

issue such messages of their own volition.

aircraft but the operative word in the message is ‘taxi’, ‘proceed’ and ‘tow’
respectively.
