Primarily used in north-westerly conditions
The PBN approach for this runway was developed earlier than the approach paths for the main runway, because there were no existing instrument approach paths to allow the runway to be used in poor visibility. The approach to this runway was used primarily for the period when the main runway concrete shoulder replacement works were being carried out over the summer of 2016 and 2017 to enable aircraft to land safely at night when visibility was low. Despite already being developed for this key safety requirement, these PBN approach paths still form part of the current Christchurch Flight Paths Trial.
