For noise abatement, flights taking off from Runway 2 are directed to climb straight ahead after takeoff until clear of the shoreline by before making any turns. Flights taking off from Runway 5 for destinations east or west are directed to turn left as soon as possible to clear the shoreline by ; flights from Runway 5 for destinations south are directed to turn right as soon as possible. Flights landing on Runway 2 detour west of Kahului and Wailuku on a heading almost directly south before lining up for landing. Flights landing on Runway 5 follow the coastline and avoid overflying populated areas as much as possible.
