Radar Observer · Operation — Parallel Index
Parallel indexing on a radar is a technique used to:

- BMonitor own ship's progress along a planned track relative to a fixed object✓ Correct
- CIdentify AIS targets
- DRemove rain clutter
Explanation
By setting a line parallel to the intended track at the planned passing distance from a fixed, identifiable object, the navigator can see at a glance whether the ship is staying on track or being set off, a powerful tool for confined-water piloting.
