Isi rekomendasi
The Air Traffic Services (ATS) provided in Tambolaka Aerodrome Flight Information Zone (AFIZ) were flight information, alerting, and, if required, air traffic advisory services. The Tambolaka ATS provider did not provide air traffic control services that contain clearance and/or instructions, as the airspace of the Tambolaka was Class G airspace.Some advice from the ACO given to the pilot used instruction phraseology, and the pilot sometimes requested a clearance to the ACO. These mixed-up communications indicated unclear determination of service status between air traffic control services and flight information services. The unclear determination might make the pilot assumed that the flights separation would be provided by the ATS provider.Therefore, the KNKT recommend all phraseology used while providing flight information services are conducted in accordance with the ATS SOP to make clear determination of service status air traffic control services and flight information services.
