What is a common test to check the integrity of aircraft wiring?

Continuity testing is a widely used method to ensure that electrical circuits are complete and functioning properly within an aircraft's wiring system. This test verifies that there are no breaks or interruptions in the circuit that could lead to electrical failure. By running a small electric current through the wires, continuity testing allows technicians to check if the electricity flows through the entire circuit as intended. If the circuit is intact, the resistance will be low, and the tester will indicate continuity.

This testing is particularly crucial in aviation, where reliable electrical systems are essential for the safe operation of the aircraft. It helps identify issues such as damaged wires, corroded connections, or faulty components that could potentially compromise the performance of various systems on the aircraft.

Other options, such as pressure testing or thermal imaging, serve different purposes and may not specifically evaluate the integrity of wiring. Pressure testing is typically associated with checking fluid systems, while thermal imaging can be used for detecting hot spots or electrical overloads but does not confirm circuit continuity. Visual inspection can help identify obvious damage or wear but is not a definitive test for electrical integrity without additional testing methods like continuity testing.
