The JEFPO One Departure is an RNAV instrument departure procedure at Seattle-Tacoma International Airport (SEA), available only between 10 PM and 6 AM local time, designed to route departing aircraft northwestward via a series of waypoints toward JEFPO. Aircraft departing runways 34L, 34C, and 34R must climb on a heading of 344° and maintain a minimum climb rate of 500 feet per nautical mile up to 940 feet, then follow specific tracks depending on their runway. Departures from runways 16L, 16C, and 16R are not authorized under this procedure, reflecting noise abatement and air traffic control considerations for the surrounding communities.Open full document
