Definition
A method of testing electronic equipment in which the test equipment is built into the unit being tested, allowing the system to check its own operation and report faults without external test gear.
Plain English
A way of testing equipment where the testing tools are built right into the equipment itself, so it can check whether it is working properly on its own.
Context Anchor
Seen in aircraft maintenance, troubleshooting, and system checks after repair, replacement, or installation.
Derivation
From Latin 'integrare', meaning 'to make whole' or 'combine into one'. The testing function is combined into the equipment itself rather than kept as a separate tool.
Why Pilots Care
Reveals interaction problems that isolated tests miss, directly affecting flight safety and airworthiness.
Intuition Check
Integrated testing does not just mean a more detailed test. It means the connected parts are tested together in the way they are meant to operate.
Example Sentence 1
The new transponder uses integrated testing, so the pilot can run a self-check from the cockpit before departure.
Example Sentence 2
Before releasing the aircraft, maintenance completed integrated testing of the electrical and hydraulic systems.
