ICAO approach classifications
Instrument licences are divided between 2D and 3d IAP endorsements, and there are cases where pilots do not have access to a 2D IAP, or in some remote areas no access to 3D IAP.
2D IAP are divided between:
- Lateral guidance with Course Deviation Indicator, and
- Azimuth Guidance via a relative bearing indicator.
An instrument rating initial issue must test a 2D IAP ref>https://www.casa.gov.au/licences-and-certificates/pilots/ratings-reviews-and-endorsements/instrument-ratings/instrument-approach-operations#2DIAPand3DIAPendorsements</ref> [1].
2D IAP covers:
- NDB
- VOR and LOC [note 1]
- DGA (DME/GNSS arrival)
- RNAV GNSS LNAV (RNP LNAV) or RNAV GNSS LP (RNP-LP)
3D IAO covers:
- Precision: ILS with LOC and GS
3D does not cover:
- RNAV GNSS VNAV [note 2]
recency
Recency requirements to conduct an IAP:
- 3D IAP - an approach must have conducted in last 90 days
- 2D IAP - lateral and approach must have conducted in last 90 days
- Azimuth IAP - an Azimuth approach must have been conducted in the last 90 days
notes
- ↑ If you have shown competency conducting VOR approaches, CASA considers you skilled enough to conduct LOC approaches
- ↑ Even if your aircraft system displays GS, due to advisory limitations and the lack of IAP minimas published in Australiam an VNAP approach does not satisfy the requirements of demonstrating a 3D approach.
