Aviation safety explained

CASA's role

The Civil Aviation Safety Authority is Australia’s air safety regulator.

It sets the rules for aviation safety in Australia and is responsible for ensuring that the aviation industry understands and complies with those rules.

If you fly regularly, you may have been on a flight that was preparing to land but the pilots chose to pull out of the approach to the airport instead. They may have gained altitude, circled the airport and lined up for another approach to landing.

In aviation terminology, this is called a go-around. It is a common and very safe practice that pilots are trained for when everything is not quite right for landing.

Adventure flights

Australia’s aviation safety regulations allow the operation of a range of ex-military aircraft in adventure-style flights. These flights are marketed as warbird, combat, military, top-gun or adventure flights.

The safety risks involved in these flights are very different to those of public passenger aircraft, and people booking such flights and those intending to fly on them should be very aware of the warnings associated with them.

Read how those safety risks of these flights are managed.

Expert Panel on Aircraft Air Quality

In response to public interest and available research CASA established a reference group to examine the potential health and safety risks through the Expert Panel on Aircraft Air Quality.

The panel was tasked with the following terms of reference:

  1. Establish the current state of knowledge in relation to human safety and health risks from the quality of air on-board commercial aircraft.
  2. Recommend whether the current research initiatives being undertaken internationally were sufficient, or whether additional research would be required in an Australian context.
  3. Recommend any further actions that should be taken in relation to human safety and health risks.

Many of the recommendations are outside the scope of CASA's functions under section 9 of the Civil Aviation Act 1988. To address the recommendations the report was forwarded to agencies in Australia and overseas.

CASA has not made policy directions or regulatory decisions based on the panels recommendations in the absence of definitive evidence. CASA believes the current incident reporting regime is adequate and the aviation industry is aware of its reporting responsibilities to the ATSB.
