... what they hadn't catered for was poor ATC vectoring, inadequate charting of an approach, and specifically tiredness.
The "specifically tiredness" also applies to ATC, so in that respect any laxity in ensuring vectors and assigned altitudes at way-points were adhered to, adds to the mess. By that I mean if they had been vectored to the FAF and at BASKIN advised to be at or no lower at IMTOY than 1380' - "If NOT visual with the PAPI", this accident would not have happened. The MDA of 1200' would then just be the 'back-up'.
Having said that, they met the above, but no one would expect them to be descending at 1500fpm in an attempt to intercept the notional PAPI NPA.
