What S/I do TCAs have enabled?

• A. Instrument interface
• B. Weapons control and Equipment control
• C. System integration
• D. Safety interlocks

Answer: (B)

TCAs provide the interfaces and signaling that let you manage the armament and the attached equipment. They translate operator commands into actions for the weapons and gear, and they report back status and fault information to the user. That focus on controlling both weapons and equipment is why this option best fits what the S/I enabled by TCAs does. Instrument interfaces are about sensors, system integration is a broader goal, and safety interlocks are a safety feature; none of these capture the core role of TCAs as cockpit-to-weapon/equipment control interfaces.
