    Mountain 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.
