NPRM 1401AS - Off-shore helicopter instrument flight procedures
The current instrument approach design criteria have not changed for many years and reflect a reliance on land-based navigation facilities that, in many cases, are not relevant to off-shore operation off the Australian coast. Further, the criteria do not reflect the use of GNSS technology.
This proposed amendment introduces GNSS as an adjunct to the existing airborne radar approach techniques and removes reference to the use of non-directional radio beacons (NDBs) as an alternative navigational option. It also introduces the concept of a 15 NM minimum separation from land which, in turn, requires that the definition of 'off-shore installation' in regulation 173.030 of the Civil Aviation Safety Regulations 1998 (CASR) be modified to permit these instrument procedures to be designed by authorised designers rather than certified designers.
