Seatle ARTCC
Cascade Chaos
The Seattle ARTCC (ZSE) Presents - Cascade Chaos!
Saturday, September 24, 2005
1900Z - 2400Z
Coming soon, Seattle ARTCC and Vancouver FIR will be fully staffed to simulate real world operations to and from the respective airspaces. The major airports of Portland International, Seattle-Tacoma International and Vancouver International will be staffed to facilitate arrivals and departures. Pilots are asked to reserve a real world flight and fly it at the specific time it arrives or departs one of the airports in order to simulate a steady and realistic flow of traffic. All real world international and domestic flights to and from the participating airports from 1900z-2400z will be available for reservation, but should you wish to fly another flight not listed, you are more than welcome to arrive or depart during this period of time.
Clearances will be slow, controllers will be taxed, traffic will be heavy. Be ready for chaos in the skies over the Cascades on Saturday, September 24th, 2005.
Portland International Airport - KPDX
Airport Diagram:
KPDX
Preferred Departure Procedure: RIVER6
Notes: There are three arrivals into Portland. The BONVL4 hosts arrivals from the east, the MOXEE6 brings in arrivals from the south and southwest, while the HELNS4 brings in arrivals from the north and northwest. While there are several charted departure procedures, the preferred departure from Portland is the RIVER6 departure for noise abatement. Be aware, this procedure requires a turn to intercept either the R-277 or R-085 radials outbound from the Battleground (BTG) VOR after departure to stay over the river. Pilots can expect radar vectors enroute shortly after departure.
