CONTAMINATED RUNWAY (P/CG) - A runway is considered contaminated whenever standing water, ice, snow, slush, frost in any form, heavy rubber, or other substances are present. A runway is contaminated with respect to rubber deposits or other friction-degrading substances when the average friction value for any 500-foot segment of the runway within the ALD falls below the recommended minimum friction level and the average friction value in the adjacent 500-foot segments falls below the maintenance planning friction level. CONTERMINOUS United States - The forty eight adjoining states and the District of Columbia. CONTINENTAL UNITED STATES - The 49 states located on the continent of North America and the District of Columbia. CONTINENTAL UNITED STATES (JCS) - United States territory, including the adjacent territorial waters, located within the North American continent between Canada and Mexico. CONTROL AREA - (See Controlled Airspace) CONTROL SECTOR (P/CG) - An airspace area of defined horizontal and vertical dimensions for which a controller, or group of controllers, has Air Traffic Control responsibility, normally within an Air Route Traffic Control Center or an approach control facility. Sectors are established based on predominant traffic flows, altitude strata, and controller workload. Pilot-communications during operations within a sector are normally maintained on discrete frequencies assigned to the sector. (See Discrete Frequency) CONTROL SECTOR (ICAO) - A subdivision of a designated Control Area within which responsibility is assigned to one controller or to a small group of controllers. CONTROL SLASH - A radar beacon slash representing the actual position of the associated aircraft. Normally, the control slash is the one closest to the interrogating radar beacon site. When Air Route Traffic Control Center radar is operating in narrow band (digitized) mode, the control slash is converted to a target symbol. CONTROL ZONE - (See Controlled Airspace) CONTROLLED AERODROME (ICAO) - An aerodrome at which Air Traffic Control service is provided to aerodrome traffic. NOTE: The term "Controlled Aerodrome" indicates that Air Traffic Control service is provided to aerodrome traffic but does not necessarily imply that a Control Zone exists. CONTROLLED AIRSPACE (P/CG) - An airspace of defined dimensions within which air traffic control service is provided to IFR flights and to VFR flights in accordance with airspace classification. (1) Controlled airspace is a generic term that covers Class A, Class B, Class C, Class D, and Class E airspace. (2) |
