REPUBLIC OF PERILO AIR TRAFFIC CONTROL SYSTEM

The Air Traffic Control System operated by the Department of Aviation provides for the safe navigation of scheduled airline service, other commercial service, and general aviation within the Republic.

The airspace of the Republic is controlled by the Glencoe Air Route Traffic Control Center (ARTCC).  Radar control is conducted by civilian air traffic controllers at the ARTCC for aircraft within 200 miles of Glencoe (at high altititude), and within 200 miles (at high altitude) of Georgetown and Astoria by civil air traffic controllers operating from military facilities.  All other en route control is procedural. 

Aerodromes and airways are depicted on the standard Airways and Aerodromes Chart, updated periodically by the Department of Aviation.  Specific restrictions to flight, special conditions, and other information of interest to airmen are published as required by the Department of Aviation as Notices to Airmen (NOTAMs).

Two high altitude instrument flight rules airways cross the Republic:

• RED 1 - from the north over the Astoria VOR to Glencoe VOR to Georgetown VOR.
• RED 2 - Hogben non-directional beacon to Glencoe VOR to the Zanzibar non-directional beacon.

Established low altitude visual flight rules airways include:

• GREEN 1 - Hogben to Clarksburg to Georgetown
• GREEN 1 OIL FIELD EXTENSION - Georgetown to Petroport to King 1 Oilfield
• GREEN 2 - Georgetown to Ashby to Portsmouth
• GREEN 3 - Glencoe to Plank Road Junction to Portsmouth
• GREEN 4 - Astoria to Cripple Creek
• GREEN 5 - Glencoe to Port Stanley to Portsmouth
• GREEN 6 - Hogben to Glencoe to Zanzibar
• GREEN 7 - Georgetown to Plank Road Junction
• GREEN 9 - Fort Wellesley to Astoria to Glencoe

Low altitude airways were originally marked by a visual beacon system with tower mounted rotating green and white beacons located approximately every 30 miles along the airway.  These beacons remain in place, but the system has not been a priority for maintenance funding, and at any time approximately 30% of the total number of beacons are out of service. 

Radar approach control services are available at Georgetown, Portsmouth, Port Stanley, Glencoe, Hogben, and Astoria.  Airport control towers with visual control operate at Petroport, Ashby, Plank Road Junction, Clarksburg, Alamance, Zanzibar, Cripple Creek, and Fort Wellesley.  All other airports are required to have a staff member on duty with the ability to monitor the published unicom frequency during the hours the airfield is open. 

Airfields with control towers have a control zone which extends to 5000 feet 15 miles from the airport.  Aircraft entering the control zone are required to contact the tower.  All other airports have an airport traffic area extending to 2000 feet 10 miles from the airport - aircraft entering an airport traffic area are required to announce their presence and intentions on unicom.

Flights crossing the Great Forest, Lake Stanley, the Northern Massif and Sangre de Cristo Mountains, or flying to the King 1 oilfield are required to file flight plans with Glencoe Center.  Use of flight plans by all aircraft is encouraged for any flight that will travel more than 20 miles from the home airport.
