Aircraft engine testers test the performance of all engines used for aircraft in specialised facilities such as laboratories. They position or give directions to workers positioning engines on the test stand. They use hand tools and machinery to position and connect the engine to the test stand. They use computerised equipment to enter, read and record test data such as temperature, speed, fuel consumption, oil and exhaust pressure.
Excludes aircraft engine inspector.

ISCO skill level
ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:
- the nature of the work performed in an occupation in relation to the characteristic tasks and duties
- the level of formal education required for competent performance of the tasks and duties involved and
- the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.
Aircraft engine tester is a Skill level 3 occupation.

- Operate precision measuring equipment: Measure the size of a processed part when checking and marking it to check if it is up to standard by use of two and three dimensional precision measuring equipment such as a caliper, a micrometer, and a measuring gauge.
- Perform test run: Perform tests putting a system, machine, tool or other equipment through a series of actions under actual operating conditions in order to assess its reliability and suitability to realise its tasks, and adjust settings accordingly.
- Diagnose defective engines: Diagnose engine damage or malfunctions by inspecting mechanical equipment; utilise instruments such as chassis charts, pressure gauges, and motor analysers.
- Read standard blueprints: Read and comprehend standard blueprints, machine, and process drawings.
- Use testing equipment: Use equipment to test performance and operation of machinery.
- Read engineering drawings: Read the technical drawings of a product made by the engineer in order to suggest improvements, make models of the product or operate it.
- Conduct performance tests: Conduct experimental, environmental and operational tests on models, prototypes or on the systems and equipment itself in order to test their strength and capabilities under normal and extreme conditions.
- Use technical documentation: Understand and use technical documentation in the overall technical process.
- Evaluate engine performance: Read and comprehend engineering manuals and publications; test engines in order to evaluate engine performance.
