    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
    The learner is able to identify and solve problems in which responses display that responsible decisions using critical and creative thinking have been made by:
  • Identifying the appropriate distress and urgency communication procedures in a real or simulated situation and adhering to them.
  • Performing the required actions in the event of communication failure in a real or simulated situation.
  • Using air traffic control terminology and procedures and adhering to ATC requirements in real or simulated flight operations.

    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.
