Hi BOAC (and thank you for the "score"),
You're right about 205 Kts a NOMINAL IAS for CAT D A/C.
It's just that PANS OPS specifies that the OCA must include a provision for 25 Kts wind + altitude :
"7.2.3 Determination method
The radius is determined using the formulas in Section 2, Chapter 3, “Turn area construction”, by applying a 46 km/h (25 kt) wind to the true airspeed (TAS) for each category of aircraft using the visual manoeuvring IAS from Tables I-4-1-1 and I-4-1-2 in Chapter 1. The TAS is based on:
a) altitude: aerodrome elevation + 300 m (1 000 ft); and
b) temperature: ISA + 15°."
thus, they end up with the figures I quoted. (See table I-4-7-2 ; Volume II).
Concerning crews's recent experience (no matter Islamabad being "A" ; "B" ;or "C"), I cannot imagine either of the pilots NOT flying to Islamabad during the past few months (Airblue is based in Pakistan ; Islamabad is the capital of Pakistan, right ?).
Flying once to an airport makes you current with this airport for one more year. (At least with my airline...).
