ISLAMABAD, Pakistan (AP) - Airports, hospitals and a major electrical company in Pakistan are not ready for the Year 2000 computer bug, the man who heads Pakistan's Y2K team said Monday. Ijaz Khawaja, the national Y2K coordinator, said none of the airports in the country have fully converted their equipment and computers to guarantee a smooth transition when computer clocks turn from 1999 to 2000. "Aviation is an area of very grave concern to us," he said. The Civil Aviation Authority promises the airports will be ready by the end of the first week  in December, Khawaja said.
