The four exhibits shown on the following pages represent the primary final arrival corridors and initial departure corridors for aircraft operating at OIA and OEA. These corridors represent where the majority of aircraft overflights occur, however, some aircraft overflights will occur outside of these flight tracks. The arrows shaded in blue are the primary arrival corridors. Arrows shaded in green are the primary departure corridors. The size of the arrows on all exhibits indicates the relative arrival and departure activity. The larger the arrows, the greater the number of aircraft operations.

Exhibit 1 depicts aircraft flow to the south at OIA. This represents the primary flow of aircraft at the airport, occurring about 85 percent of the time. Exhibit 2 depicts northerly flow at OIA. This represents the primary areas of overflights the remaining 15 percent of the time. It should be noted that a fourth runway on the east side of the airport is under construction. The flight corridors presented on Exhibits 1 and 2 include the primary locations of arrivals and departures operating to and from this new runway.

Exhibit 3 depicts the primary flight corridors for west flow at OEA. Exhibit 4 depicts the primary flight corridors for east flow at OEA. West flow at OEA occurs approximately 40 percent of the time. East flow occurs about 60 percent of the time. The noisiest locations for OIA and OEA are generally the closest to the airports and toward the center of the corridors.
