Safety issue: RNAV (GNSS) approach late notice of air traffic control clearance

Late notice of clearance by air traffic control to conduct an RNAV (GNSS) approach was identified as the most common difficult external condition affecting an RNAV (GNSS) approach, particularly for high capacity airline pilots. An examination of opportunities to improve training and/or procedures for air traffic controllers to help ensure timely approach clearances is warranted.

Safety Recommendation

The Australian Transport Safety Bureau recommends that Airservices Australia, in conjunction with the Civil Aviation Safety Authority, address this safety issue.

Response text:

Airservices canvassed several airlines to establish how early the clearance for RNAV (GNSS) approaches needs to given. Consequently, a notice to air traffic controllers was developed for educational purposes. This notice provided the following information for air traffic controllers.

In circumstances that necessitate ATC nomination of an RNAV (GNSS) approach, early approach expectation should be provided to pilots. The preferred minimum notice is five minutes prior to top of descent.

This information was also brought to the attention of the Airservices training college for the purpose of updating the basic training material. In addition, CASA were consulted on this process.
