Which tool is used to locate hidden hotspots inside an aircraft structure during firefighting?

• A. Water pressure gauge.
• B. Ground-penetrating radar.
• C. Thermal imaging camera.
• D. Video camera.

Answer: (C)

Locating hidden hotspots inside aircraft structures relies on detecting residual heat that can reignite. A thermal imaging camera detects infrared radiation emitted by surfaces and translates it into a visual image of temperature differences. This lets firefighters see hot spots behind panels, within wings, fuselage sections, or cargo areas, even through smoke and darkness, so they can cool and extinguish precisely where needed. A water pressure gauge measures hose or pump pressure, not heat. Ground-penetrating radar looks for buried or hidden objects in the ground, not internal hot spots during a fire. A video camera provides only what is visible in light and is blocked by smoke, so it can’t reliably reveal hidden heat sources. Therefore, the thermal imaging camera is the best tool for this purpose.
