Project AS 12/22 - Review of CAAP 178-1(1) 'Non-Precision Approaches'

Topic code: 
Airspace and Aerodromes
Project status: 
Closed

Closure notes

Project closed 25 October 2012.

CAAP 178-1(2) Non-precision Approaches (NPA) & Approaches with Vertical Guidance (APV) has been published.

Issue

CAAP 178-1 was issued in October 2004. During the intervening period, changes to the design of non-precision approach (NPA) procedures have been promulgated by ICAO and these changes are being incorporated into published procedures. The proposed project will amend the CAAP to incorporate these new ideas.

If the CAAP remains unchanged, it will convey out of date information that will both serve to confuse industry and reflect poorly on the credibility of other information contained in the CAAP.

The deficiencies in the CAAP include:

  • No mention in the CAAP of the Visual Segment Surface that was introduced in 2007 and is progressively being applied to all Australian NPAs.
  • No mention in the CAAP of Approaches with Vertical Guidance (APV). Although these are not NPAs, their imminent introduction as a complement to and relationship with NPAs does need explanation.
  • The CAAP states that helicopter procedures to emergency sites are not published in DAP (para 7.3). These procedures are now published in DAP.
  • The discussion of circling procedures in AIP has changed with related paragraph changes. The CAAP still refers to the previous paragraph numbers.

Many abbreviations have been changed by ICAO (eg, LLZ to LOC, GPS to GNSS) and these changes need to be incorporated in the CAAP.

Project Objective

The project will re-write CAAP 178-1 to address the issues mentioned above.

No other documentation will be affected by this proposal.
