    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
    Identify and solve problems that occur between the various interrelated equipment/components of radar detection and transmission systems to ensure optimum performance. 

    UNIT STANDARD CCFO WORKING 
    Work effectively with other members of the team responsible for the compliance and performance of the equipment used in aviation radar detection and transmission. 

    UNIT STANDARD CCFO ORGANISING 
    Employ self management by ensuring sufficient time is allocated for carrying out the initiation or restoration of radar detection and transmission systems. 

    UNIT STANDARD CCFO COLLECTING 
    Manage information contained in data specifications for test equipment and diagnostic systems, information supplied in handbooks, maintenance schedules and performance logs to ensure accurate evaluation of radar detection and transmission 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 team members and the client. 

    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 surveillance display systems 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.
