14. หลักฐานที่ต้องการ (Evidence Guide)

(a) Performance Evidence

     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:

•   Using hand skills, tools and test equipment in the testing, adjustment and troubleshooting of instrument and display systems.

•   Recognition of system and component defects/external damage, correct installation, connection of plugs, terminations, and attaching hardware (including cabling/harnesses) for the systems listed in Range of Conditions.

•   Interpreting the information presented on instrument and display systems.

•   Applying logic processes and using appropriate wiring diagrams and manuals to isolate instrument and display system malfunctions.

•   Performing system functional tests and checks to isolate system faults and assess post-maintenance serviceability.

•   Effectively using maintenance documentation and relevant fault diagnosis guides in the troubleshooting process.

•   Applying standard procedures.

•   Observing all relevant WHS procedures.

It is essential that system testing procedures, cleanliness requirements and safety precautions applicable to the instrument system being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice across a range of inspection, testing and troubleshooting applications (including the timely involvement of supervisors or other trades) is critical. 

Evidence of transferability of skills and knowledge related to testing and troubleshooting is essential. This may be demonstrated through application across a range of aircraft instrument and display systems (where display systems are applicable to the enterprise) listed in the Assessment Description and Procedure. 



(b) Knowledge Evidence

     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 basic knowledge of:

•   Standard trade practices relating to tool and test equipment usage and installation/securing of system components

•   The basic layout (block diagram level) of the systems listed in the Range of Conditions.

•   The operating principles of the systems listed in the Range of Conditions and associated with:

•   The properties and effects of atmospheric conditions on aircraft instruments and systems.

•   Pressure and temperature sensing elements and their use in aircraft instruments.

•   Gyroscopes and their use in aircraft instrument and reference systems.

•   Electrical fundamentals and display screen generation.

•   The various methods of navigation and how they are used by both conventional and electronic navigational instruments and systems.

•   Maintenance requirements and troubleshooting procedures.

•   WHS procedures relating to instrument and display systems and components.

•   Relevant maintenance manuals.

•   Relevant regulatory requirements and standard procedures, including software management control.


15. ขอบเขต (Range Statement)

This part allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

 Instrument or display systems include:   

•   Flight instruments – pitot/static systems, airspeed indicators (ASIs), machmeters, air data systems and instruments, vertical speed indicators (VSIs), altimeters, altitude alerting and reporting, turn and bank, directional gyros (DGs), artificial horizons (AHs), angle of attack, stall warning/avoidance, ground proximity warning system (GPWS) and flight data recorders (FDRs).

•   Engine instruments – engine speed, pressure, temperature, performance, vibration and torque.

•   Instrument navigation systems – inertial navigation system (INS), inertial reference system (IRS), compasses and attitude and heading reference system (AHRS).

•   Miscellaneous – pressure, fuel quantity, fuel flow, position, voltage, frequency, current and power.

•   Display systems – electronic flight instrument system (EFIS), engine indicating and crew alerting system (EICAS), flight management computer system (FMCS), electronic central aircraft monitor system (ECAM) and head-up display (HUD) (where applicable to the enterprise).

•   Integrated modular avionics (where applicable to the enterprise)

     Procedures and requirements include:   

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

18. รายละเอียดกระบวนการและวิธีการประเมิน (Assessment Description and Procedure)

The assessment are based on combination of paper exams, interviewing, and practical demonstrations depending on the assessors’ judgement.

•   Competency should be assessed in the work environment or simulated work environment, using procedures, tools and equipment specified in maintenance documentation. It is also expected that general purpose tools, test and ground support equipment found in most routine situations would be used where appropriate. The level of troubleshooting is limited in its application to the use of fault diagnosis guides or other similar information to enable troubleshooting to line replaceable item level.

•   The application of testing procedures should clearly indicate knowledge of system operation, the relationship of individual components and the links with other systems (if applicable) within the limits of the aircraft/system fault-finding guide 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 this unit of competency are being achieved under routine supervision on a system and on at least one (1) major system component of each of the following groups:

•   Flight instruments – pitot/static systems, ASIs, machmeters, air data systems and instruments, VSIs, altimeters, altitude alerting and reporting, turn and bank, DGs, AHs, angle of attack, stall warning/avoidance, GPWS and FDRs.

•   Engine Instruments – engine speed, pressure, temperature, performance, vibration and torque.

•   Instrument navigation systems – INS, IRS, compasses and AHRS.

•   Miscellaneous – pressure, fuel quantity, fuel flow, position, voltage, frequency, current and power.

•   Display systems – EFIS, EICAS, FMCS, ECAM and HUD (may be omitted if not applicable to the enterprise).

•   Integrated modular avionics (may be omitted if 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.
