What the Hill?

If you are reading this, you are probably wondering – what has “Checkerboard Hill” got to do with Hong Kong?

Sporting ground at Kowloon Tsai Park

Located on the edge of Kowloon City, the hill was located beneath the final approach to runway 13 at the non-closed Kai Tak Airport, and had a large checkerboard red and white pattern painted onto the hillside as a navigational aid. To steal from Wikipedia, after reaching the hill aircraft landing at Hong Kong would execute the following manoeuvre:

Upon reaching a small hill marked with a checkerboard in red and white, used as a visual reference point on the final approach (in addition to the middle marker on the Instrument Guidance System), the pilot needed to make a 47° visual right turn to line up with the runway and complete the final leg. The aircraft would be just two nautical miles (3.7 km) from touchdown, at a height of less than 1,000 feet (300 m) when the turn was made. Typically the plane would enter the final right turn at a height of about 650 feet (200 m) and exit it at a height of 140 feet (43 m) to line up with the runway. This manoeuvre has become widely known in the piloting community as the “Hong Kong Turn” or “Checkerboard Turn”.

This photo by Daryl Chapman shows how tight the final approach was, taken from the west side of the airport with the checkerboard in the background.

My first visit to Hong Kong was in February 1998, during the final months of Kai Tak being on operation. I was lucky enough to staying with family members who lived right beneath the flight path in Kowloon City, but unfortunately the shorter version of myself didn’t think to waste film on the planes flying above me. As a result, this is the only photo I have in my collection.

Hindsight is a beautiful thing…

    Pretty cool info. I just finished a hike on checker board hill and whats left of old Kai Tak, Great photos!

    • Do you know the size of the Checkerboard ?

      • The southern face of the painted ‘checkerboard’ is 6 squares high by 11 squares across – if each square is two metres across, that makes it 22 metres long by 12 metres high, or about as tall as a three story building.

        Comparing the height of the hill to the pink building in front of it (Holy Family Canossian College) suggests the hill itself is around 12 storeys high, or 35 metres tall.

        Finally, I played around with the elevation data from this website:
        http://www.mapcoordinates.net/en

        The foot of the hill is about 30 meters above sea level, while the top of the checkerboard is 75 metres – so again about 35 metres.

  4. Thank you for the reply, that was really helpful

    Sitting on top of Chequerboard Hill right now. A lovely, but rather warm, December day.

    I used to land 747s and Airbuses at Kai Tak. The new airport is not nearly so fun.

      I feel so lucky to have had a chance to interact with the old Kai Tak airport, even though I was limited to 3 landing and take-offs (as a passenger) in 1997 and 1998. The new place is just boring like all major airports these days.
