Explanatory Statement
Civil Aviation Act 1988
Instructions — specifying minimum runway width for an aeroplane
Section 98 of the Civil Aviation Act 1988 (the Act) provides that the Governor-General may make regulations for the purposes of the Act and for the safety of air navigation.
Under subregulation 235A (1) of the Civil Aviation Regulations 1988 (CAR 1988), to ensure the safety of air navigation, CASA may issue instructions specifying the minimum runway width applicable to an aeroplane or a type of aeroplane. Under subregulation 235A (2), it is an offence for the pilot in command of an aeroplane to land at, or take-off from, a runway if its minimum width is less than the minimum specified for that aeroplane or aeroplane type. Under subregulation 235A (3), an instruction does not have effect in relation to a person until it has been served on them or published in the AIP.
In instrument number CASA 407/98, CASA has issued instructions specifying the minimum runway width for aeroplanes. The required width depends on the aeroplane’s characteristics, including its reference field length (generally meaning its required take-off distance), its wing span and its outer main gear wheel span. The maximum runway width required for the largest size of aeroplane covered by the instructions (i.e. with a wing span of up to 65 metres) is 45 metres.
The instructions do not cover an aeroplane like the Airbus Industrie prototype A380-841 whose wing span exceeds 65 metres. Also, the Manual of Standards Part 139 — Aerodromes made under the Civil Aviation Safety Regulations 1998 (the MOS) requires that the operator of an aerodrome runway provide a runway of 60 metres width for an aircraft the size of the A380-841, subject, however, to any variation made by instructions issued under subregulation 235A (1) of CAR 1988.
Airbus Industrie (the operator) proposes to bring the prototype A380-841 (the aircraft) to Australia between 11 and 16 November 2005, inclusive, for airport evaluation. The operator has requested that it have permission to land and take-off at Brisbane International Airport, Sydney International Airport and Melbourne International Airport (the airports), all of whose runways are effectively not wider than 45 metres.
Having considered the safety implications of the proposal, CASA has decided to give the permission in the form of instructions to the effect that, when operating at 1 of the airports, the minimum runway width applicable to the aircraft may be 45 metres. Such operations must also conform with the requirements of the special flight authorisation issued by CASA to enable the prototype aircraft to operate in Australian airspace. Operations must also comply with any operating limitations specified in the temporary permit to fly issued by the Direction Generale de l’Aviation Civile, the French civil aviation authority.
Legislative Instruments Act
Under section 5 of the Legislative Instruments Act 2003 (the LIA), an instrument is a legislative instrument if it is of a legislative character, for example, by determining the content of the law rather than applying the law in a particular case. The instructions are, therefore, a legislative instrument and are subject to tabling and disallowance in the Parliament under sections 38 and 42 of the LIA.
Consultation under section 17 of the LIA has not been undertaken in this case. The instrument is highly specific. It has been requested by the operator to enable it to bring the aircraft to Australia for airport evaluation purposes at Australia’s main international airports, into and out of which it would be likely to operate in the future.
The instrument, which commences on 11 November 2005, has been registered on the Federal Register of Legislative Instruments. It stops having effect at the end of 16 November 2005.
The instrument has been made by the Group General Manager, Air Transport Operations, a delegate of CASA, under subregulation 7 (1) of CAR 1988.
