Flight Information Service - Airspace

Airspace

AFIS is provided at the aerodrome and in the surrounding airspace. The airspace in the immediate vicinity of the aerodrome is internationally called TIZ – Traffic Information Zone (some nations have other words and abbreviates e.g. the UK as seen below) The traffic information zone is equivalent to the controlled aerodromes CTR – control zone. Above the TIZ most AFIS aerodromes have a TIA – Traffic Information Area equivalent to the controlled aerodromes TMA. The TIZ and TIA are most commonly airspace classification G but with the additional regulation of mandatory two way radio communication., commonly called G+. In some nations the airspace classification F is also used.
