Expanding aprons Incheon Airport’s apron traffic is among the highest in the world. The COVID-19 pandemic

to revitalize the exacerbated this issue as idle aircraft accumulated, leading to overcrowding at aprons and parking
stands. With space increasingly scarce, expanding aprons (stands) became urgent. Delays at the
airport apron could disrupt passenger service and even increase the risk of accidents.

In preparation for increased air traffic, Incheon Airport expanded the apron area alongside the
construction of Runway 4, building a total of 62 passenger aprons and 13 cargo aprons to optimize
aircraft parking. This expansion increased Incheon Airport’s total apron capacity from 239 stands

(as of 2020) to 330, addressing the previous shortage.
For passenger aprons, attached aprons at Terminal 2 employed the Multi Aircraft Ramping
System (MARS), maximizing space by allowing two small (Code C) aircraft to park where one
large (Code F) aircraft would typically be stationed. For cargo aprons, construction was carried

out with consideration of the future expansion of the cargo terminal's operations, securing 13
multi-purpose parking stands connected to the area in front of the cargo terminal.
Additionally, 11 centralized deicing stands were introduced by converting remote aprons from
Phase 3. These deicing stands were designed to allow deicing operations with engines running,

taking into account the engine exhaust. Deicing waste collection pipelines were also installed. The
capability to perform deicing with engines on reduced average takeoff times by 16 minutes and
supported flawless winter operations through the latest deicing technology.
