    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 microwave system. 

    UNIT STANDARD CCFO WORKING 
    Work effectively with others by ensuring equipment performance evaluation is relayed to the Flight Calibration Unit when performing flight checking procedures on microwave system. 

    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 microwave systems 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 communication control systems 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 microwave systems. 

    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.

    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.
