Speaking of AYT, since last August they have gone mad with SIDs, STARs and approach procedures after adding RNAV. For the four runways normally used (two N, two S) there are now 19 pages of STARs ad 49 of SIDs. There are seven pages of approaches in one direction, a mix of ILS, LOC and VOR, and 16 pages in the other direction. STAR and landing direction are specified in descent but frequently changed on intermediate approach. VHF freqs are very congested. All this whilst descending into high MSAs.
I don't claim this had anything necessarily to do with the accident but it's quite a distraction.
