The info that i have got is that aircraft was cleared to do a bad weather circuit and at islamabad only runway 30 has ils ( instrument landing system ) and 12 does not have it, so this means he was making a visual approach, and at islamabad, in bad weather there is windshear. PIA flight diverted to lahore 20 mins before the airbleu reached islamabad.

The capt pervaiz chaudhry was a retired PIA captain.
