Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This field 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.

Ancillary equipment includes one (1) or more of the following:

pumps

compressors

fluid power equipment

metering equipment

electrical controls

electronic controls

Gas turbine engine andcomponents include one (1) or more of the following:

engine change unit, main components and accessories/drives

control components, including valves, meters and regulators

ignition and starter system components

fuel system components, including:

manifold and nozzles

combustion chambers

filters

oil system components

air system components, including:

air inlet structures

fans

guide vanes

centrifugal or axial flow compressor assemblies (low and high pressure)

compressor bleed valves if fitted

exhaust system components, including:

high and low pressure turbine assemblies

free turbine (where fitted)
