2023-11-06History of air traffic control
Simon Golstein At any given moment, there are more than 10,000 aircraft in the air. They fly along the same routes and use the same airports, taking off and landing within moments of each other. And yet, statistics show that flying is by far the safest way to travel. This is thanks to air traffic -
Close Calls and the New York Times: What You Need to Know
The U.S. aviation system is the safest in the world, but one close call is one too many. The FAA and the aviation community are pursuing a goal of zero serious close calls, a commitment from the Safety Summit in March. The same approach virtually eliminated the risk of fatalities aboard U.S. commercial airlines. Since 2009, -

2022-07-14Mountain Two Departure (MONTN2.SEA) — Seattle-Tacoma International Airport Standard Instrument Departure
The Mountain Two Departure (MONTN2.SEA) is an instrument departure procedure for Seattle-Tacoma International Airport (SEA) that provides pilots with specific climb and routing instructions based on which runway they are using. Departing aircraft must meet minimum climb gradients ranging from 500 to 580 feet per nautical mile depending on the runway, and are directed to fly specific headings before turning eastbound on a 071° heading toward fixes like PEAKK or NEZUG. The procedure requires radar and DME equipment, with top altitude assigned by ATC and a lost communications protocol directing pilots to proceed direct to the SEA VORTAC at 4,000 feet. -

2022-07-14ELMAA Four Departure (ELMAA4.ELMAA) — Seattle-Tacoma International Airport Standard Instrument Departure
The ELMAA Four Departure is a standard instrument departure procedure for Seattle-Tacoma International Airport (SEA) that routes aircraft southward after takeoff on runways 16L, 16C, or 16R. Departing aircraft climb on headings of 161°–165°, cross the PEAKK waypoint at or above 3,000 feet, then turn right to intercept the SEA R-230 radial toward the ELMAA fix, with onward transitions available to Hoquiam (HQM) or Corvallis (CVO). Notably, departures from runways 34L, 34C, and 34R are not authorized due to noise abatement restrictions, and minimum climb gradients of up to 560 feet per nautical mile are required depending on the runway used. -

2022-05-19Seattle Eight Departure (SEA8.SEA) — Standard Instrument Departure Chart
The Seattle Eight Departure (SEA8.SEA) is a standard instrument departure procedure for Seattle-Tacoma International Airport, outlining specific climb headings and routes for each runway to guide aircraft safely after takeoff. A notable noise-abatement provision requires large turbine-powered aircraft departing runways 34L, 34C, and 34R between 10 PM and 6 AM local time to be vectored over Puget Sound before proceeding on course. The procedure requires radar and assigns top altitude by ATC, with special minimum climb gradients applicable to runways 16R and 16L.
