      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:

•   Locating and identifying flight instrument system components comprising:

•   Engine system temperature, pressure (including thermocouples, sensor units and transmitters), speed (including mechanical and electrical tachometers), thrust (fan, propeller and jet), torque, fuel flow and vibration.

•   Auxiliary systems, including hydraulic pressure and temperature, transmission pressure and temperature, fuel storage quantities, fuel remaining/used, component position, i.e. flaps, landing gear, speed brakes and door/pylon locking.

•   Flight systems, including attitude, altitude, air speed, OAT and GPWS (where applicable to the enterprise).

•  Locating and identifying direct reading compasses, remote compass system components (flux valve, gyro, amplifier and indicator), and AHRS components.

Procedures and requirements include:

• Industry standard procedures specified by manufacturers, regulatory authorities or the enterprise.

The assessment are based on combination of paper exams, interviewing, and practical demonstrations depending on the assessors’ judgement. Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine maintenance situations would be used where appropriate. An understanding of the attachment methods, connection of hardware, and the need for adjustment or calibration and system operation as they relate to the work must be demonstrated before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards. An individual cannot be evaluated as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria of the unit of competency are being achieved under routine supervision on at least one (1) component from each of:

Pitot/static system components, ASIs, VSIs, air data system components, machmeters, altimeters, including servo and encoding altimeters, angle of attack and stall warning/avoidance systems.

• Transmitter/indicator measuring instrument systems (pressure, temperature, position).

• Fuel quantity indication and flow systems components.

• GPWS (may be omitted where not applicable to the enterprise).

• FDR (may be omitted where not applicable to the enterprise).

This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.
