PLA firing range poses a threat to planes using Hong Kong’s proposed third runway
Planes performing emergency manoeuvres will have to avoid two major obstructions

A firing range used by the PLA and police poses a hazard to planes that would use the third runway at Chek Lap Kok, a government source has told the Post.
A plane approaching the runway needs a certain amount of airspace in case it needs to abort the landing at the last minute.
Frequent firing by troops at the Castle Peak site, which sits under an escape-route flight path earmarked for the planned new runway, threatens to reduce such airspace and limit the number of planes that can land.
The skies above Castle Peak are designated a no-fly zone under 914 metres during security exercises, which are often held from Monday to Friday throughout the year. Planes will have to climb much steeper to avoid the no-fly zone, increasing the risk of the manoeuvre.

A Civil Aviation Department source said the government remained open to its consultant's warning and that the firing range could be moved before the third runway was completed - but this would mean the PLA having to cede control of a key resource.
