Unit Of competency

Modification History

Release 1. This is the first release of this unit of competency in the AVI Aviation Training Package.

Application

This unit involves the skills and knowledge required to control a helicopter in hovering flight, in compliance with relevant regulatory requirements of the Civil Aviation Safety Authority and national operating standards.

It includes lifting off to hover and performing hovering checks, hovering a helicopter in cross and tail winds, performing turns around the mast, conducting turns around nose and tail, and performing sidewards and backwards flight. It also includes landing from the hover, managing a mishandled landing, and managing a mishandled lift off.

This unit addresses aviation technical skill requirements (physical, mental and task-management abilities) related to aircraft operational duties of flight crew, and contributes to safe and effective performance in complex aviation operational environments.

Operations are conducted as part of recreational, commercial and military aircraft activities across a variety of operational contexts within the Australian aviation industry.

Work is performed independently or under limited supervision within a single-pilot or multi-crew environment.

Licensing, legislative, regulatory or certification requirements are applicable to this unit.

Use for Defence Aviation is to be in accordance with relevant Defence Orders, Instructions, Publications and Regulations.

6 

Land from the hover 

6.1

Pre-landing checks are completed as required

6.2

Helicopter is lowered onto nominated point from hovering flight without adverse longitudinal, lateral, yawing or rolling movements

6.3

Helicopter stability on landing gear is ensured prior to fully lowering collective

6.4

After-landing checks are performed

7 

Manage a mishandled landing 

7.1

Appropriate action is taken to identify when an adverse landing situation is developing

7.2

Appropriate action is taken to either land aircraft or discontinue landing and return to hover safely

8 

Manage a mishandled lift off 

8.1

Appropriate action is taken to identify when an adverse lift off situation is developing

8.2

Appropriate action is taken to discontinue lift off and return to ground safely
