Yesterday I had FNLU approach open for over 3 hours. Part way into the session, tower asked if I could put some planes on 25 as the 23 back taxi and a constant backlog of planes crossing 25 was becoming problematic.
I decided to use a single line and alternate planes between 23 and 25. This would open up spacing for 23 while allowing me to close up spacing in the air. The feedback from tower was positive so it went that way for a few hours at least.
I was using GPS approaches for 25 and ILS for 23. It was my mistaken understanding that if GPS was available to me as an approach controller, that there were fixes down the localizer. Unfortunately, that wasn’t the case, so there was no way you could create a quick flightplan down the localizer for use with GPS in NAV.
Everyone flew the approach down 25 without incident so I applaud the pilots that handled that difficult situation. This may be changing soon, but from now on I won’t be specifying GPS approaches.
