Caution shall be used when using which device due to limited field of view and lack of depth perception?

• A. Night Vision Goggles ( NVG )
• B. Binoculars
• C. Cameras
• D. Tow bar

Answer: (A)

Limited field of view and degraded depth perception are characteristic of Night Vision Goggles. The image intensified view gives you a bright grayscale image but with a narrow viewing cone, so you can’t see well to the sides. Because depth cues are reduced, judging distances becomes unreliable. In tow and brake operations on the ramp, that means you must move slowly, stay in clear communication with a ground guide, and verify all clearances before moving to avoid striking equipment, personnel, or aircraft. The other devices don’t impose the same combination of tunnel vision and depth ambiguity in typical use: binoculars still allow two-eyed viewing with better depth cues, cameras can have varying fields of view and don’t inherently impair depth perception the way NVGs do, and a tow bar is not a viewing device at all.
