During night jump operations, what color light is mounted on the chest of the jumpers?

• A. White
• B. Red
• C. Green
• D. Blue

Answer: (B)

During night jump operations, the color light mounted on the chest of jumpers is red. The choice of red light serves several important purposes in this context. Red light is less likely to compromise the night vision of jumpers and anyone observing them, enabling personnel to maintain their ability to see in low-light conditions. This is critical during jumps, as it allows jumpers to navigate and maintain situational awareness without blinding themselves or others.

Additionally, red lights are also easily identifiable, allowing jumpers and aircraft personnel to quickly recognize each other, which is essential in ensuring safety and coordination. The other colors, while visible, do not provide the same level of compatibility with night vision adaptation and could hinder safe operations under the cover of darkness. Thus, the use of red light is a well-established practice driven by the necessity for both visibility and night operational effectiveness.
