I can’t think of any way to make the 530 use the GINIA missed. You’d probably have to do it manually. Probably have to ‘deactivate’ the approach or whatever the terminology is, plug in Direct GINIA and then go OBS with a 272 Course To. Probably easier to just VLOC your way onto the 272 radial or use a VHF NAV if you have one in the airplane. Maybe there’s something easier than either of those, I dunno.
Should you/must you notify ATC or not that you’re going to do it. I probably would. Like “if I miss I’m going to GINIA.” Is it required to notify them? The Chart says “DME equipped aircraft...” Equipped. So what does that mean? GPS is an authorized substitute for DME. So do you run with that? Or take it literally that when they say ‘equipped with DME’ they mean ‘equipped.’ Anyway, all that gibberish aside I’m pretty sure it’s not going to be an issue. I’m pretty sure they are going to tell you to do the GINIA thang if you miss. ATC usually don’t have warm feelings about course reversal, right back up into the face of the next airplane type of missed approaches. Look at the link below. This Approach does not have an Alternate Missed Approach Procedure. If it did, it would say so. The Missed Approach is in the upper right and then continues to the next page. Kinda implies what I said above about how they are just going to probably give you the GINIA thing.
@aterpster ,
