    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
    Identify and solve problems when carrying out fault diagnosis thereby ensuring that appropriate remedial actions are initiated for the effective restoration of failed or defective Recording and Play-back systems equipment. 

    UNIT STANDARD CCFO ORGANISING 
    Employ self management by ensuring sufficient time is allocated for carrying out general housekeeping activities in addition to maintenance or repair work to Recording and Play-back systems equipment situated in remote locations. 

    UNIT STANDARD CCFO COLLECTING 
    Collect, analyse, organise and critically evaluate information contained in data specifications for test equipment and diagnostic systems, information supplied in handbooks, maintenance schedules and performance logs to ensure optimum recording and playback equipment support and maintenance requirements. 

    UNIT STANDARD CCFO COMMUNICATING 
    Communicate effectively ensuring that information communicated via technical reports is accurately recorded in a neat and logical format that can be readily accessed and understood by end-users and that ongoing oral communication is maintained with calibration teams and Air Traffic Control during preventive or corrective maintenance operations carried out on Recording and Play-back equipment. 

    UNIT STANDARD CCFO SCIENCE 
    Demonstrate scientific and technological competence by applying knowledge and understanding of scientific processes to the correct use of sophisticated, high technology test equipment and diagnostic systems. 

    UNIT STANDARD CCFO DEMONSTRATING 
    Demonstrate an understanding of the world as a set of related systems by recognising that the role of the technician is a vital part of the integrated radio communication system which is used by Air Traffic Control, Airline Pilots and the flying community at large and as such should therefore not be regarded as a role which is performed in isolation of this network.

    REREGISTRATION HISTORY 
    As per the SAQA Board decision/s at that time, this unit standard was Reregistered in 2012; 2015. 

    UNIT STANDARD NOTES 
    Supplementary Information:

    Routine maintenance schedules have been prepared and are in place for each system based on manufacturers' recommendations, operational requirements and support requirements determined from actual field experience during the operational life of the systems.

    International Civil Aviation Organisation (ICAO) recommendations publish recommendations and standards for all communications, navigational and surveillance systems used in aviation. The ICAO Annex 10 publication includes the recommendations and standards to be adhered to ILS systems.

    Flight Checking Procedures involves the South African Civil Aviation Authority carrying out regular flight calibration checks on all ILS systems in South Africa to ensure the accuracy of the navigation information provided to pilots by these ground based navigation aids. Systems found complying with the SACAA criteria and ICAO recommendations are then certified by the SACAA for operational use for the certification period up until the next flight calibration check.

    Corrective maintenance procedures include procedures contained in equipment manufacturer manuals, ICAO recommendations and site specific maintenance procedures.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
