ICAO Approach Classifications
ICAO approach classifications
The 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 [1] .
2D IAP covers:
- NDB
- VOR and LOC (if you have shown competency conducting VOR approaches, we consider you skilled enough to conduct LOC approaches)
- 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 even if your aircraft system displays GS due to advisory limitations and the lack of IAP minimas published in Australia
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
