PRA....hmmmm those were the days! Withdrawn from Oz and NZ many years ago, technology caught up with us
Think the UK and maybe the US are the only people left in the world doing them....
Was always handy having a window that faced the threshold from the GCA room and do a legendary 'talk down to touchdown' by pulling the drapes back and watching the jet first hand, alternatively open the hotline to the tower and get them to relay the amounts of feet until the aircraft touched the deck!
Still think its a valuable ATC mechanism for recovering acft, unfortunately my opionion is in the minority when it comes to 'progress'
