Which device is used in total darkness?

• A. FLIR
• B. Radar
• C. NVG
• D. Infrared Sensor

Answer: (C)

Night vision devices rely on making the dark visible by boosting whatever light is present. Night Vision Goggles amplify ambient light—from starlight, moonlight, or nearby sources—so the pilot sees a usable, head-up image of terrain, obstacles, and runways. This makes them the go-to tool for flying when the sky is essentially dark, because they provide real-time, cockpit-level vision without needing external lighting. Other options rely on heat signatures or radio echoes to provide information (infrared/thermal sensors and radar), which offer different kinds of data but don’t produce the direct visible scene that NVGs give you for night flight.
