What is the purpose of the "yellow jersey" worn by personnel on the flight deck?

• A. To signify individuals involved in fueling operations
• B. To indicate a flight deck officer or landing signal officer
• C. To denote personnel responsible for aircraft maintenance
• D. To show involvement in logistics operations

Answer: (B)

The yellow jersey worn by personnel on the flight deck serves to indicate the presence of flight deck officers or landing signal officers. These individuals are critical to the safe and efficient operation of aircraft during launch and recovery operations. Their responsibilities include directing the movements of aircraft and ensuring that all flight operations are conducted smoothly and safely. The visibility of the yellow jersey helps everyone on the flight deck quickly recognize who is in command and can give instructions, which is particularly important in the high-pressure environment of flight operations where clear communication and authority are essential for safety.

In contrast, the other options refer to different roles that are signified by other colors or clothing, emphasizing that the yellow jersey has a specific connotation that is distinct from the other functions on the flight deck.
