Six night slots for operations between 1600-2059 UTC will be made available daily for those aircraft types not currently listed in Annex 3 of Schedule Coordination Guidelines. Slot requests for GABA operations may be considered from time to time depending on availability of various capacity constraints. For the full night period, from 1400 through 2259 UTC, the total of available slots remains nine for all aircraft types not currently exempted from the Noise Quota Count Pilot Scheme. The Hong Kong Schedule Coordination Office also noted that to maximize the utilization of last-minute canceled commercial service slots outside of the night period, slot requests by general and business aviation operations might be considered depending on availability.
To further maximize the utilization of last minute cancelled slots outside the night period by commercial services, slot requests for GABA operations may be considered from time to time depending on availability of various capacity constraints. The trial period for these additional slots ends March 31 2019
