Answer»

The correct answer is (b) Provide target locking capabilities by looking at the target

Explanation: A HELMET Mounted Sights in combination with a head tracker system provides effective means for the pilot to lock on to target. The pilot can look at the ENEMY aircraft and lock on to it. The relative position of the enemy is then calculated by the head position of the pilot and SENT to missiles to ENGAGE the target. A typical seeker head NEEDS to be pointed to within about 2° of the target to achieve an automatic lock on.
