Hold before approach question.

[JordanD]

Really basic question that I ought to know the answer to.
Is a hold at Nabb required if atc tells you "cleared for the approach", or can you just proceed direct Nabb and then inbound to intercept the localizer? Provided you aren't in a position where you need to do the procedure turn at Catch.

The hold at NABB is for the missed. The NoPT on the route from NABB to the LOC means no procedure turn.

In short go to NABB go west track lil loc thingy to runway get BBQ.

That's what I figured but I had a few CFIs make it seem like you had to at least do a hold entry before proceeding towards the loc.

????? On this approach?

That's a little funny...but mostly scary.

Yeah but looking back I don't know if I misunderstood them or they always made me do it for practice. But it seems like they never let me go direct to Nabb then inbound.

I agree, that's a bit horrifying that you had multiple CFIs tell you that. The dashed line holding pattern on NACO charts always refers to the missed approach procedure.

Check out the ILS or LOC Rwy 11 at San Luis Obispo, CA for an example of when a holding pattern would be part of the approach:

As you can see the IAFs at FRAMS int and PRB VOR are marked "NoPT" and you would not execute the hold from either. You would use the holding pattern for course reversal if coming from MQO VOR on the 307 deg (8.5 nm) 4000 ft feeder route (which looks almost identical to regular radials on the NACO charts, but contains that additional heading/distance/altitude information).

But as you can see, the hold in this case is solid and highlighted in bold, indicating that it's part of the approach. The dashed holding pattern at MQO is part of the missed approach.

Hope that helped.

It did! I haven't shot that one in ages and kinda had a "wait...why were we always doing that?" moment.

Maybe it depended upon the direction that you were approaching NABB? There is a note that you cannot use NABB as an IAF if you approach it from the southwest (radials 174 CW 267), and if you were arriving from that direction maybe they just used the holding pattern as a home-made course reversal to come back to the IAF on a valid radial. If you were above 2600 feet (missed approach holding altitude) you would certainly be in protected airspace.

I don't know - that's probably reaching for a valid reason.
