I used to do PAR approaches in RAF Chipmunks. My instructor once had me continue right down to touchdown, following the controller's instructions. A very impressive system. Of course, you have to have complete faith in the controller.
I'm not talking about the pro flyers
Even pros struggle with it sometimes. I watched an RAF Tristar doing what was obviously a bad NDB 16 approach at Calgary once. I was in the terminal, which is near the threshold. The Tristar was outbound from the MM Charlie beacon and at least ten degrees off track, heading straight for the terminal. At MDA, there was a sudden turn right! The rest of the crew must have been laughing their heads off!
