The Australian Transport Safety Bureau recommends that
Airservices Australia review the design of STARS and Instrument
approaches with a view to improving separation assurance during
communications or radar failure.
Strategic separation assurance is built into Airservices'
procedures (eg. SID/STAR arrangement) and these procedures are
generally applicable within 20NM of Sydney Airport. From that point
tactical separation, including where practicable, separation
assurance is applied as necessary. Application of a more rigid
strategic separation assurance methodology within the 20NM radius
would adversely affect traffic management flexibility and
capacity.
Airservices has reviewed current procedures and as a result
considers that the current arrangements provide sufficient defence
in the event of communications or radar failure. In the incident
that is the subject of this report, separation was maintained
throughout.
Airservices is conducting a further review of existing procedures
to ensure consistency of application and publication.
A review as recommended has been conducted at Sydney. Amendments
deriving from the review will be a review as recommended has been
conducted at Sydney. Amendments deriving from the review will be
published in DAP on 14 Feb. and in ERSA in March. Completion date
extended to March in line with the above.
