NOISE ABATEMENT PROCEDURES
North Flow



The Initial Departure Corridor is 4 degrees each side of the
341 degree radial of the Sea-Tac Airport VOR, extending 8
DME north of the Airport and a minimum altitude of 4,000
feet before turning.
Between the hours of 10:00 pm and 6:00 am jet aircraft departing north are vectored west over Elliott Bay, then turned north or south over Puget Sound once out of Elliott Bay.
South Flow


The initial Departure Corridor is 4 degrees each side of the
161 degree radial extending 5 DME south of the airport and a
minimum altitude of 3,000 ft before turning.
Reverse Thrust


Between the hours of 10:00 pm and 7:00 am, the use of
extended reverse thrust is discouraged beyond what is
necessary for operational or safety reasons.

CONTINUOUS DESCENT ARRIVAL (CDA) - NONE

AIRPORT CURFEWS
Prior to the phase-out of Stage 2 airplanes over 75,000 lbs in the U.S., there was a curfew on those operations at the airport.

PREFERENTIAL RUNWAYS
During nighttime hours, 10pm to 6am, it is preferred that aircraft equipped with flight management system (FMS) operate through the North Flow Nighttime Noise Abatement Corridor. This measure is operational when traffic and other conditions permit, as determined by the FAA. In such conditions, during nighttime hours, departures can be shifted from south to the north, thus utilizing the established noise abatement corridor. This procedure is limited to those times when it can be done safely and efficiently.

OPERATING QUOTA - NONE

ENGINE RUN-UP RESTRICTIONS
All engine run-ups require approval of Airport Operations. No aircraft engine run-up shall be conducted between the hours of 2200 and 0700 except:

a. Aircraft that are regularly scheduled to depart between the hours of 0600 and 0830 shall be allowed to run-up as necessary between 0600 and 0700.
b. Engine runs necessary for engine checks at idle power or, if absolutely necessary, a run-up above idle not to exceed a total of two (2) minutes duration during this designated quiet period shall be allowed.

Operations not in accordance with the run-up regulations are subject to public disclosure and fees as stated in the Sea-Tac International Airport Tariff #1.


Based on these Run-Up Restrictions, Tarriffs have been implemented.
As of April 30, 2003 the fines associated with violating the run-up restrictions are:
First offense in one year = Letter of Admonishment
Second offense in one year = $1,000
Third offense in one year from first offense = $2,000
Maximum fine within one year from first offense = $8,000

APU OPERATING RESTRICTIONS - NONE

NOISE BUDGET RESTRICTIONS
Sea-Tac's Noise Budget Program was a 10 year program designed to speed up the phase-out of Stage 2 aircraft. This program ended in the year 2001, when all Stage 2 aircraft above 75,000 lbs. were phased out.

NOISE SURCHARGE - NONE
