Isnt PPI supposed to mean Plan Polar Indicator? This to distinguish it from the early radar displays only showing targets in one specific direction. Anyone? europrobe 18:22, 1 November 2005 (UTC)[reply]

Plan Position Indicator is the original TRE (who devised it) meaning and is fairly self-explanatory. The display gives a map-like, ie., a plan display of the target positions relative to the transmitting set. Ian Dunster 11:38, 14 November 2005 (UTC)[reply]
