Recommendation issued to: Airservices Australia and the Civil Aviation Safety Authority

Recommendation details
Output No: R19970067
Date issued: 30 June 1997
Safety action status: Closed
Background:

The manual of Air Traffic Services (MATS) details separation standards to be applied for situations where intersecting runways are in use (MATS 6-3-4/5/6 paragraphs 23, 27 and 35) and where there are intersecting approach paths (MATS 6-3-6 paragraph 36). However, there is no standard described for those situations where the approach/departure path of one runway intersects the area between the two thresholds of another runway. This can lead to uncertainty as to the correct standard to be used. This uncertainty becomes more relevant when the two runways are in close proximity and the runway strips do not infringe each other. There are 12 locations in Australia which have control towers and similar runway configurations.

Output text

The Bureau of Air Safety Investigation recommends that Airservices Australia and the Civil Aviation Safety Authority (CASA) review the application of separation standards for all controlled aerodromes with intersecting approach/departure paths and runways. The review should ensure that there is no uncertainty in the application of separation standards.
