The Three-Runway System (3RS) commenced operations on 28 November 2024. At present, the HKIA has three runways (commonly called the North Runway, the Centre Runway and the South Runway) running northeast to southwest. Under normal circumstances, the 3RS at the HKIA is operated according to the primary mode of operation outlined in Hong Kong International Airport Master Plan 2030, i.e. the North Runway is dedicated to arrivals, the Centre Runway to departures, and the South Runway operates in mixed mode for both arrivals and departures. However, depending on the actual situation and operational needs (e.g. carrying out necessary maintenance works), the HKIA will be operated in dual runway mode or single runway mixed mode. Where maintenance works must take place to ensure safe operation, they are usually conducted during non-busy periods from late night to early morning to minimise impact on airport operation.

三跑道系統於2024年11月28日起展開運作。現時香港國際機場有三條跑道（稱為北跑道、中跑道及南跑道），由東北至西南方向伸延。在一般情況下，三跑道系統會按照《香港國際機場2030規劃大綱》提到的主要模式運作（即北跑道用於航機降落、中跑道用於航機起飛、及南跑道用於航機混合起飛及降落) 。然而，因應不同實際情況及運作需要（例如進行必要的維修保養），香港國際機場會以雙跑道模式或單跑道混合起降模式運作。維修保養通常安排在深夜至清晨的非繁忙時段進行，以確保跑道供飛機安全使用和減低對機場運作的影響。
