Sorry about that! PURPA is the waypoint on the Pakistan/Indian/Chinese border and the only way we can do the Japan/Korea northern route out of Dubai. The reference to the 250 knots is due to the general speed restriction below 10,000 feet AGL required by ATC and our company, it was slightly sarcastic as IAS at our typical cruising levels is below that anyway, we just have to put up with a lot of anally retentive nifnaf sometimes, but the price we pay!
