Notice of Final Rule Making
- Carriage and Use of Radio and Circuit Procedures at, or in the Vicinity of, Non-towered Aerodromes - Amendments to CARs 166 & 166A
Following extensive industry consultation, Characteristic 29 of Stage 2c of the National Airspace System (NAS) was introduced on 24 November 2005 by amendment to Civil Aviation Regulations 1988 (CAR) 166 and 166A. CAR 166A designates certain non-towered aerodromes (currently known as Common Traffic Advisory Frequency (Radio) CTAF(R)) in the vicinity of which the carriage and monitoring of radio and the making of specified positional broadcasts by pilots is mandatory. Currently, radio carriage and use in the vicinity of other non-towered aerodromes (known as CTAFs) is recommended rather than mandated.
Regulatory changes relating to the radio requirements introduced in 2005 have been the subject of further extensive industry consultation and review over the last 3 years. Certain decisions on revised radio monitoring and broadcasting requirements at non-towered aerodromes were announced by the former CASA Director on 17 October 2008. However, the current Director reviewed those decisions and broadened the scope of the proposals to include certain changes to circuit procedures, as a result of which NPRM 0908OS was promulgated for comment.
The views of those who agreed or disagreed with these proposals were often expressed with equal passion. Sport and recreational aviation stakeholders continued to consider that no or only general or limited requirements relating to use of radio should be mandated. Professional aviation stakeholders continued to take a generally opposite view. Consequently, it has been necessary for CASA to decide on a way forward with respect to these matters.
The originally proposed radio use requirements for pilots overflying, within the vicinity of, a non-towered aerodrome were particularly controversial. They appeared to be applicable at all aerodromes whether marked on aeronautical charts or not and however rarely used. Proposals to rectify this were the subject of a dedicated NPRM 0814OS which closed for comment on 23 December 2008. However, the proposals contained in NPRM 0908OS superseded those in the earlier NPRM but took comments received on that NPRM into account.
More detailed background information relating to the development of the proposals can be found in NPRM 0908OS.
