Learning objectives
- Know how to use HAD
- Know how to use WPN page
- Know when and how to use POS (EOM, PB, RUK)
- Know when and how to use HAS
POS
POS will always slave to a selected steerpoint; no steerpoint means no shot in POS mode
- Manually select steerpoints or threat steers in HSD or jump to pre-planned target steerpoints using UFC
- Alternately, set mark points as references to radars to use POS mode
- In POS, you can use EOM (very fine control – you know exactly where the target is and it is on the current steerpoint), PB (wider control – the target is close to a threat steer point), or RUK (extremely wide control – the target is around your current position and will lock on to the first thing it sees). You still need a steerpoint, remember.
- RUK is LOAL, HAS is LOBL.
- RUK, PB, EOM are all three POS modes and all POS modes are steerpoint-directed in azimuth. The difference is in end game seeker activity and assumed range only. EOM and PB assume range = range to steerpoint. RUK assumes range = maximum.
- EOM = point
- PB = area
- RUK = lane
- RUK is for painting a long, wide stripe of ground with HARM coverage. PB is for a floodlight on an area. EOM is a laser pointer.
