General aviation at Kai Tak was rare and highly restricted, especially during the final years of that airport, thanks to the heavy commercial traffic. The Hong Kong Aviation Club did have an few light aircraft, but they were only given slots during the early morning hours, from the lifting of the nighttime curfew (0630) until just before the first morning peak period (approx. 0830). Due to such restrictions, most of the time, they will simply operate out of the small airstrip at the Sek Kong military base up north. With Kai Tak closed, the Club is now based entirely at Sek Kong.
Since, the runway at Kai Tak is sooooooooo much longer than what those light planes will ever need, they can basically make their approach from any direction. Once in a while, some of them would emulate the big birds and do the checkerboard approach. Piece of cake for those light planes really.
