Elements and Performance Criteria

1. Design an aerobatic sequence
   • Performance parameters are identified based on physical limitations of pilot and structural limitations of aircraft
   • Sequence of aerobatic manoeuvres is designed that meets a specified requirement
   • Practical transitions are included between aerobatic manoeuvres
   • Performance parameters are identified based on a combination of aircraft attitude, power setting, altitude and speed that provide go-no-go guidance for safe completion of all manoeuvres above safety height
2. Perform aerobatic sequences above specified safety height
   • Specified sequences of manoeuvres are completed in accordance with aerobatics design
   • Performance parameters required for safe completion of a manoeuvre are achieved prior to commencement
   • Orientation with display axis is maintained
   • Energy potential of aircraft is managed to ensure completion of manoeuvres and sequences of manoeuvres within aircraft structure and minimum height limits
   • Failure to achieve performance parameters (energy requirement) to complete a manoeuvre is recognised and aircraft is managed to regain control above safety height
   • Height at or above a specified altitude is maintained

Range Statement

Range is restricted to essential operating conditions and any other variables essential to the work environment.
