If you are flying for an airline (US) the PAR must be in your ops specs. My outfit has both captains and F/Os demonstrate proficiency in the sim. We see them mostly at USN bases now a days but a certified controller is not always available. An interesting side note is that you can initiate the approach even if the field is below minimums if the PAR is flown with an ILS tuned. (FAR 121) Watch the movie "Strategic Air Command" to see Jimmy Stewart fly the GCA (old guys name for the PAR) into Kadena in a B47. Great fun.
