What does the PFE S/I do?

• A. The system will disable engagement processing until a target is confirmed.
• B. The computer will process a track for engagement and send the engage command only once the PK is at an optimal level
• C. It updates engagement parameters automatically every cycle
• D. It requires manual confirmation before engaging

Answer: (B)

This tests how engagement decisions are controlled by a target’s kill probability. The PFE S/I is responsible for evaluating a tracked target and deciding when to engage based on PK. The idea is to process the track and only issue the engage command when the probability of a successful kill is at an optimal level, balancing effectiveness with resource use and risk. This means engagement isn’t triggered immediately on track processing or left to manual confirmation; it waits for the PK to reach the predefined threshold where the intercept is most likely to succeed. The other options don’t capture this decision logic: engagement isn’t automatically withheld until a target is confirmed, nor is the primary function simply to update parameters every cycle, nor is manual confirmation required.
