Ground based approaches such as SRAs and PARs aren't flown often at civvy airfields these days, although military trained pilots are (or were) very well versed in them as some mil aircraft didn't have ILS not long back.
A few years ago, at Kai Tak, a typhoon was going through the area and the eye of the storm had just passed. This meant the very strong wind sudden;y reversed in direction, causing a runway change. The first aircraft onto RW31 couldn't receive the ILS and carried out a missed approach.
ATC told the second aircraft that the ILS hadn't come on line and they were being vectored for a PAR approach instead. The crew asked for the message to be repeated twice then asked what a PAR was!
The controller said "Precision Approach Radar"!!
To my amazement - the pilot answered, in a nervous sounding voice: "We cannot do a PAR because we don't have that equipment fiitted!"
Eh? ATC had no option but to make them climb back into the stack until the ILS came on line!
