Nb. Islamabad (ISB/OPRN) has the following approach to Runway 30 (runway QDM = 296 degrees) :
ILS DME - inbound QDM = 296 degrees / visibility minima for Cat C aircraft = 700m
ILS LOC - inbound QDM = 296 degrees / visibility minima for Cat C aircraft = 750m
VOR DME - inbound QDM = 296 degrees / visibility minima for Cat C aircraft = 1100m
VOR Circling - inbound QDM = 340 degrees / visibility minima for Cat C aircraft = 2400m
NDB Circling - inbound QDM = 320 degrees / visibility minima for Cat C aircraft = 2400m
Had they been following a standard 3 degree approach, in the above reported (METAR) visibility of 3000 metres (approx 1.6Nm), they should have expect to see the runway when at approximately 500 feet above ground level.
If Pakistani news reports are correct, i.e. that they crashed at / into the village of 'Hussain Abad' ( N33° 35' 19.48" / E073° 8' 51.69" ), that puts the crash site approximately 2.1 Nm short of the threshold for R30. It is also approximately 0.3 Nm to left of the R30 extended centreline.
Given that they should have been following a 3 degree glide path (regardless of the approach type), this might suggest that - at the point of impact - they were approximately 600 feet below an ideal (3 degree) glide path and also substantially left of the centreline of R30.
