    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO WORKING 
    Work effectively with others when liasing with Air Traffic Controllers and other role players in the ATM environment. 

    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 Air Traffic Control during the monitoring and operation of Communications systems. 

    UNIT STANDARD CCFO SCIENCE 
    Demonstrate scientific and technological competence by applying knowledge and understanding of scientific processes to the correct understanding of sophisticated, high technology communications 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 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.
