AVIY4018B
Manage abnormal and emergency helicopter flight situations

This unit involves the skills and knowledge required to correctly manage abnormal situations that may occur during a helicopter flight. Abnormal situations may include a forced landing from level flight, after take-off or on approach; or an engine failure at the hover or during taxi. Abnormal situations also include a tail rotor malfunction, jammed flight control system, adverse aerodynamic conditions, or a malfunction of one of the helicopter's operating systems. Licensing, legislative, regulatory or certification requirements are applicable to this unit.

Application

Work must be carried out in compliance with the relevant licence and aircraft rating requirements of the Civil Aviation Safety Authority (CASA) and/or ADF; airspace control requirements and Day Visual Flight Rules (Day VFR); and aircraft control principles, regulations, safety codes, protocols and procedures required to manage abnormal and emergency helicopter flight situations.

Use for ADF Aviation is to be in accordance with relevant Defence Orders and Instructions and applicable CASA compliance.

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

Work is performed under limited supervision.

This unit of competency is nominally packaged at Certificate IV.

Note:

Where an abnormal situation might potentially cause damage to the aircraft and/or be harmful to personnel, evidence for assessment purposes should be obtained from other than observation of performance in an actual abnormal operational situation (e.g. through using an appropriate simulator and/or structured questioning, or termination of a simulated forced landing at a point where the assessment of an outcome can be made).


Prerequisites

Not applicable.
