Assessment requirements

Modification History

Release 2. Equivalent to MEA271 Lay out avionic flight management systems with amended prerequisite codes.

Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

  • sketching typical avionic flight management systems at block diagram level.

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Knowledge Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

  • the atmosphere
  • pitot static systems
  • magnetism
  • function of gyroscopes
  • use of synchros and servos
  • basics of analogue electronics
  • aircraft instrument systems and their components
