study means an investigation of a problem concerned with aircraft operations, aimed at identifying:

(a) possible solutions (if any); and

(b) the solution (if any) which best preserves an acceptable level of aviation safety.

Note   CASA guidance on aeronautical studies is contained in CASA Advisory Circular (AC) 139.A-04: Applying for aerodrome authorisations, exemptions and approvals, as existing from time to time and freely available on the CASA website.

aeroplane reference field length means the minimum field length required for an aeroplane to take off at maximum certificated take-off mass, at sea level, in standard atmospheric conditions, in still air and with zero runway slope, as shown in:

(a) the aeroplane's aircraft flight manual approved by the national aviation authority which issued the initial type certificate for the aeroplane; or

(b) equivalent data from the aeroplane manufacturer.

AFRU means aerodrome frequency response unit and is the abbreviation used for an aerodrome frequency confirmation system.

AIP means Aeronautical Information Publication.

AIP-ERSA means Aeronautical Information Publication - En Route Supplement of Australia.

aircraft classification number (ACN) means a number expressing the relative effect of an aircraft on a pavement for a specified standard subgrade category.

Note   For guidance see CASA Advisory Circular (AC) 139.C-07: Strength rating of aerodrome pavements, as existing from time to time and freely available on the CASA website.

aircraft movement means 1 of the following:

(a) the landing of an aircraft at an aerodrome;

(b) the take-off of an aircraft from an aerodrome;

(c) a touch-and-go manoeuvre of an aircraft at an aerodrome.

aircraft movements, when referred to numerically for an aerodrome, for a financial year, means the numbers of aircraft movements at the aerodrome during the financial year, as compiled by the aerodrome operator or the ATS provider.

Note   CASA may require an aerodrome operator or an ATS provider to provide it with aircraft movement data: see regulations 139.140 and 139.145 of CASR.

aircraft parking position means an open-air designated area on an apron for parking an aircraft.

Note 1   An aircraft parking position is also known as an aircraft stand.

Note 2   An aircraft parking position does not include any area that is within a fully or partially‑enclosed aircraft hangar.

Note 3   An area designated on an apron as being available for the parking of aircraft is considered to be an aircraft parking position.

airline means an aircraft operator operating aircraft in regular public transport operations.

airside means the following areas, access to which is restricted by the aerodrome operator, or by a Federal or State authority, to authorised persons only:

(a) the movement area of the aerodrome;

(b) where their purpose and use is to directly support aircraft operations — the terrain and buildings adjacent to
