As of the 27th of November 2003, ICAO established a requirement for States to set safety levels for provision of air traffic services in airspace and at aerodromes.
Here is the exact requirement from Annex 11 to the Chicago Convention, of which Australia is a signatory:
As of 27 November 2003, the acceptable level of safety and safety objectives applicable to the provision of ATS within airspaces and at aerodromes shall be established by the State or States concerned. When applicable, safety levels and safety objectives shall be established on the basis of regional air navigation agreements.
Note.- The acceptable level of safety may be specified in qualitative or quantitative terms. The following are examples of measures which could be used to express the acceptable level of safety:
a. a maximum probability of an undesirable event, such as collision, loss of separation or runway incursion;
b. a maximum number of accidents per flight hour;
c. a maximum number of incidents per aircraft movement;
d. a maximum number of valid short-term conflict alerts [STCA] per aircraft movement.
An ATS management programme shall, inter alia:
a. identify actual and potential hazards and determine the need for remedial action;
b. etc
We have not been able to find a difference that Australia has lodged to ICAO in respect of this Standard. Neither have we been able to find public data in Australia that lists the safety metrics for airspace and aerodromes.
It seems to us that any discussion on risk tolerability is moot without these metrics being available in the public domain. We have been shown risk metric material that was developed for Mr Dick Smith’s Aviation Reform Group, but we understand your regulator rejected that material. We have also seen draft guidance only material developed by your regulator, which is somewhat tired.
Can anyone provide advise on the risk metrics adopted by Australia to comply with ICAO requirements?
