PURPOSE OF THE UNIT STANDARD 
This unit standard will enable learners to describe elementary aerodynamic principles of flight that would include an understanding of the theory and the physiology of flight and principles of flight. Learners will be provided an opportunity to develop their practical skills with the essential knowledge required for air traffic services.

The qualifying learner is capable of:
  • Describe the elements of physics relating to aerodynamic principles.
  • Describe basic aerodynamic principles.
  • Explain the effects of change of control surfaces in flight.

    Learners who have achieved this unit standard will increase their opportunities for professional development and employability within the Aviation industry.

    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.
