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:
piston engine system temperature, pressure, speed (including mechanical and electrical tachometers), manifold pressure/boost (including aneroid type, sylphon bellows and dual compartment type)
gas turbine engine indicating system temperature, pressure, speed, torque, fuel flow and vibration (may be omitted if not relevant to the enterprise)
auxiliary direct reading systems, including hydraulic pressure, pneumatic pressure and vacuum, and fuel storage quantities
flight systems, including attitude, altitude, air speed and OAT
locating and identifying direct reading compasses
locating and identifying remote reading gyro compass system components (may be omitted if not relevant to enterprise)
correct handling and observance of maintenance precautions relating to gyroscopes, gimbals, pitot/static systems (connections, heating and protrusions)
applying relevant WHS practices.
It is essential that cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with, as well as work practices associated with electrostatic sensitive devices.
Evidence of transferability of skills and knowledge related to removal and installation is essential. This is to be demonstrated by application across a range of aircraft instrument system components as listed in the Assessment Conditions.
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:
component attachment methods
connection of hardware and plugs
handling precautions relating to:

atmospherics and barometry
terminology and unit of measurement conversion
aircraft instrumentation requirements
instrument panel layout
pressure sensing elements
pitot static systems and testing requirements
gyroscopic principles
direct reading compasses
remote reading gyro compasses
temperature sensors
fluid quantity indication systems
general layout and components of the following systems:
flight systems, including:
altitude (direct reading altimeters)
attitude, including directional gyros and artificial horizons (both air and electrically driven), turn and slip and turn coordinator
airspeed
OAT
remote reading gyro compass system
piton engine indication systems, including:
direct reading temperature
direct reading pressure (e.g. oil pressure)
speed, including mechanical and electric tachometers
manifold pressure/boost, including aneroid, sylphon bellows and dual compartment types
gas turbine engine indication systems, including:
temperature and pressure

torque
fuel flow
vibration
auxiliary direct reading systems, including:
electrical
hydraulic pressure
pneumatic pressure and vacuum
basic fuel quantity indication
relevant WHS practices
relevant maintenance manuals
relevant regulatory requirements and standard procedures.
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.
The following conditions of assessment represent the requirements of the Regulators (ADF and CASA) and maintenance stakeholders and must be rigorously observed.
A person cannot be assessed 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 and counter pointer altimeters
DGs and AHs, both air and electrically driven
turn and bank and slip/turn coordinators
remote reading gyro compass system (may be omitted if not relevant to the enterprise)
direct reading compasses
piston engine indication system components (direct reading measuring instruments and temperature indication)
gas turbine engine indication system components (may be omitted if not relevant to the enterprise)
electrical systems indication (voltage, current, power and frequency)
basic fuel quantity indication system components
pneumatic/vacuum indication system components.
This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines).
Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.
Individuals being assessed who have already attained MEA275 Maintain basic light aircraft instrument systems and components will have met all of the criteria for this unit. The Log of Industrial Experience and Achievement records relating to MEA275 Maintain basic light aircraft instrument systems and components may be accepted as also meeting the evidence requirements for this unit.
