Procedures

The HAROB Six Departure (RNAV) is a standard instrument departure procedure for Seattle-Tacoma International Airport (SEA) that defines specific climbing routes and altitude requirements for aircraft departing on runways 16L, 16C, 16R, 34L, 34C, and 34R. Aircraft must follow prescribed headings, reach minimum altitudes at designated waypoints, and cross the HAROB fix at or above 10,000 feet before proceeding on one of four available transitions toward destinations such as Hoquiam or Hisku. The procedure requires RNAV 1 navigation capability, radar contact, and DME/DME/IRU or GPS equipment, with specific minimum climb gradients designed to manage aircraft noise and obstacle clearance in the Seattle area.
