Flyerboyek nailed it. Whenever something that has to do with navigation, VOR, ILS, etc. goes out of service, before it comes back online FlightCheck will have to go check it out.
So it looks like some sort of instrument approach was coming back, so they have to do straight in runs, along with arcs from each side to intercept the final approach course/localizer. They can be a real pain in the you know what, because it ALWAYS seems like they want to do opposite direction stuff, but that's me probably remembering all the messed up situations because of that. If they're same direction, eh, who cares. Just another Joe Schmoe doing low approaches
