Which of the following is an example of a BITE indicator fault?

• A. Tripped circuit breakers; Lamps indicating incorrectly; Swivel lamps off when subsystem activated; Indicators displaying incorrectly; ANT ELEM counts
• B. Tripped circuit breakers; Lamps indicating correctly
• C. Lamps indicating incorrectly; Antenna ELEM counts
• D. Swivel lamps on; Indicators displaying correctly; ANT ELEM counts

Answer: (A)

BITE indicators show the status of subsystems using built-in test equipment lights and readouts. A fault in these indicators means they misstate or fail to reflect the actual condition of the system. The best choice demonstrates multiple signs that the indicator system itself is faulty: some lamps indicate incorrectly, swivel lamps stay off when the corresponding subsystem is activated (when they should be on), and the indicators display incorrect information overall. The inclusion of a tripped circuit breaker and ANT ELEM counts fits the pattern of a faulty indicator readout rather than a healthy, separate subsystem fault, reinforcing that the issue lies with the BITE indicators.

Other options either pair a fault with correct indicator behavior or show all indicators as correct, which would not indicate a BITE indicator fault.
