Why the ILS system is only installed on runway 12 and not on runway30?
Because for the prevalent winds and amount of traffic ILS on 30 is enough. Its not abnormal to have ILS only on one side of the runway even for many major airports in the world.
The ATC after miss approach on runway 30 asked the pilot of ED202 to go around and line in with runway 12 for landing as runway 12 is equipped with ILS. AS the weather was not good on the day of incident than why from the beginning the ATC had not instructed the pilot to use the runway 12 for the landing instead of runway 30.
For IFR flights there are following main procedures to land on rwy 12 though there are others too listed on the approach charts.
ONE
Flights are vectored by islamabad radar from the western side in a right hand pattern passing over Golra Round About (right base 12) at 2900 ft amsl and are alligned for finals rwy 12 and then handed over to chaklala ATC for landing.
TWO
Flights are cleared by radar for 'ILS 30-Circle to land 12'. In that the flights are vectored down to 3900 ft AMSL and are aligned with LOCALISER 30. Once established on localiser, these are handed over to chaklala ATC. The flight continues approach in landing configuration till 200 feet. Thereafter they
break off (NO Go Around) break off towards right (east) make a left hand pattern passing over shakarparian, F-9 park and align with the rwy 12 somewhere over sector G-11 for finals. Conditions being that these are not more than 5 nm away from the airfield and have the runway in sight all the time.
Please keep in mind that in both the cases explained above landing on rwy 12 is a planned procedure and not an impropmtu one. On the otherhand 'Missed approach', Go-aroúnd' and dumped landing are emergency or contigency procedures due poor visibility, obstruction on rwy or some technical reason. In such a scenario the flight usually makes another approach on the same runway or proceeds to the diversion airfield if the conditions have not improved which called for MAP, GA or dumped landing in the first place.
