CIVIL AVIATION SAFETY REGULATIONS 1998 - REG 171.010

Interpretation

  (1)   In this Part:

"accuracy" , in relation to a radionavigation service or facility, means the degree to which the value measured or displayed by the service or facility conforms to the true value.

"approval" means an approval, given by CASA, to provide a telecommunication or radionavigation service.

"availability" , for a telecommunication service, radionavigation service or support service, means the percentage of its operating hours that the service is not interrupted.

"configuration" , in relation to:

  (a)   a telecommunication or radionavigation service--means the configuration of each facility and any interconnection between facilities that make up the service; and

  (b)   a facility--means the configuration of equipment, hardware, software and data, and the interconnections between equipment.

"coverage" , in relation to a telecommunication or radionavigation service, means the volume of airspace in which, or the locations between which, the service is nominally provided.

Example 1:   The volume of airspace in which an aeronautical broadcasting service can be received and used.

Example 2:   The places served by an aeronautical fixed line telecommunication service.

"functional specification" , for a telecommunication service, a radionavigation service or a support service, is a general description of the service, its operating principles and its functions.

Example:   The functional specification of an aeronautical radionavigation service may describe the kind of service, each standard to which it operates, the accuracy of its signal and the aircraft for which the service is provided.

"hazard" means a source of potential harm to aviation safety.

"integrity" , of a telecommunication service, a radionavigation service or a support service:

  (a)   means the likelihood that the information supplied by the service at a particular moment is correct; and

  (b)   includes the ability of the service to warn users promptly when the service should not be used.

"key personnel" , in relation to a service provider, means the person or persons who manage 1 or more of the following:

  (a)   operations;

  (b)   maintenance;

  (c)   safety.

"Manual of Standards" means the document called 'Manual of Standards   (MOS) - Part   171' issued by CASA under regulation   171.017, as in force from time to time.

"operating hours" , for a telecommunication or radionavigation service, means the times during which the service provider must, under its approval, operate the service.

"operations manual" means a manual of the kind described in Subpart   171.D, prepared by a service provider or a person applying for approval.

"recovery time" means the period during which a service is interrupted.

"reliability" , of a telecommunication service, a radionavigation service or a support service, means the probability that the service will perform its function or functions without failure for a specified period.

"risk" means risk to aviation safety.

"safety" means aviation safety.

"service provider" means a person approved to operate and maintain a telecommunication or radionavigation service, and whose approval is not suspended or revoked.

"technical specification" , for a telecommunication service or facility, or a radionavigation service or facility, is a detailed description, that may use technical terms and concepts, of:

  (a)   the way in which the service or facility operates and performs its functions; and

  (b)   the technical standards to which the service or facility has been designed and manufactured.

Example:   The technical specification of a particular kind of radionavigation service may include its frequency band, channel spacing, frequency tolerance, effective radiated transmitter power, antenna type and gain, effective radiated power and radial phase modulation.

"technician" means a person who is engaged by a service provider to do 1 or more of the following:

  (a)   operate a facility;

  (b)   maintain a facility;

  (c)   conduct measurements of the performance of, and calibration of, a facility during a flight inspection.

  (2)   For this Part:

  (a)   a telecommunication or radionavigation service is provided using 1 or more facilities at 1 or more locations, each facility consisting of:

  (i)   1 item of equipment; or

  (ii)   items of interconnected equipment;

    at a particular location; and

  (b)   a service is interrupted if, during its operating hours:

  (i)   it is not operating because it has failed or has been suspended; or

  (ii)   it is operating outside its technical specification.
