Hi all,
Quick question. What's the correct course reversal from this hold to commence the approach from the overhead?
my reading is exit 309 for a minute and then left turn back to overhead and then outbound 115 on the procedure.

Without seeing all the notes for the procedure, yes you would have to fly outbound on 309 degrees and self position . Then track 115 for the procedure .

Just do an 80/260(ish) over the fix.

[aterpster]

Under PANS-OPS, when there is a base leg, you are required to enter an alignment holding pattern if your course towards the base leg is not within 30 degrees of the base leg outbound. That would be a standard holding pattern NW of SLG NDB 115 degree inbound, 3,500.

I can't make heads or tails out of that plate, I must not be very smart. Someone wanna explain to me what's going on there? What's that holding pattern even doing there?

Here's the link Sligo Approaches (http://iaip.iaa.ie/iaip/IAIP_Frame_CD.htm) it's the NDB DME 29

I am a fan of the 80/260! The wind up that part of world can make a finessed reversal challenging...

It appears to me that the holding pattern is a mistake, carried over from the NDB Runway 11 procedures, where it is the ICAO compliant base-leg alignment pattern.

Here are all the Jepp charts, so whoever cares, can try to sort it out. There is no doubt in my mind that the proper ICAO compliant was erroneously omitted from the Runway 29 procedure. But, most people probably wouldn't fly the Rwy 29 base leg because of the DME entry routes.

The Jepps plate explains it all

Care to elaborate?

Yeah, I don’t see that the Jepp plate explains anything additional.

From the snippet the OP posted I wasn't aware of the two transitions that bypass the base leg. I also infer that the SLIGO holding pattern is redundant on the Runway 29 chart.

Ah right, I suppose my point is however you end up in the hold (Go around, waiting on weather to clear, other traffic etc.), there has to be a standard way to commence the approach.
There's a similar hold up the road in Carrickfin (EIDL)

ICAO DOC 8168: When arriving overhead the beacon first time, the heading must be within certain limits(30° of the entry-track). If not, clearance must be obtained to manoeuvre to get within the limits - manoeuvring space

Typically, that holding pattern is charted on base-leg IAPs.

At EIDL the portrayed pattern serves as both the base leg alignment and missed approach holding pattern. That is good design, and typical. They should have done the same for Runway 29 at EISG.
