(Refer to AC 90-42, Traffic Advisory Practices at Airports Without Operating Control Towers.)COMPASS LOCATOR. A low power, low or medium frequency (L/MF) radio beacon installed at the site of the outer or middle marker of an instrument landing system (ILS). It can be used for navigation at distances of approximately 15 miles or as authorized in the approach procedure. a. Outer Compass Locator (LOM). A compass locator installed at the site of the outer marker of an instrument landing system. (See OUTER MARKER.)b. Middle Compass Locator (LMM). A compass locator installed at the site of the middle marker of an instrument landing system. (See MIDDLE MARKER.)(See ICAO term LOCATOR.)COMPASS ROSE. A circle, graduated in degrees, printed on some charts or marked on the ground at an airport. It is used as a reference to either true or magnetic direction. COMPLY WITH RESTRICTIONS. An ATC instruction that requires an aircraft being vectored PCG C.4 back onto an arrival or departure procedure to comply with all altitude and/or speed restrictions depicted on the procedure. This term may be used in lieu of repeating each remaining restriction that appears on the procedure. COMPOSITE FLIGHT PLAN. A flight plan which specifies VFR operation for one portion of flight and IFR for another portion. It is used primarily in military operations. (Refer to AIM.)COMPOSITE ROUTE SYSTEM. An organized oceanic route structure, incorporating reduced lateral spacing between routes, in which composite separation is authorized. COMPOSITE SEPARATION. A method of separat-ing aircraft in a composite route system where, by management of route and altitude assignments, a combination of half the lateral minimum specified for the area concerned and half the vertical minimum is applied. COMPULSORY REPORTING POINTS. Reporting points which must be reported to ATC. They are designated on aeronautical charts by solid triangles or filed in a flight plan as fixes selected to define direct routes. These points are geographical locations which are defined by navigation aids/fixes. Pilots should discontinue position reporting over compul-sory reporting points when informed by ATC that their aircraft is in “radar contact.” CONFLICT ALERT. A function of certain air traffic control automated systems designed to alert radar controllers to existing or pending situations between tracked targets (known IFR or VFR aircraft) that require his/her immediate attention/action. (See MODE C INTRUDER ALERT.)CONFLICT RESOLUTION. The resolution of potential conflictions between aircraft that are radar identified and in communication with ATC by ensuring that radar targets do not touch. Pertinent traffic advisories shall be issued when this procedure is applied. Note: This procedure shall not be provided utilizing mosaic radar systems. CONFORMANCE. The condition established when an aircraft’s actual position is within the conformance region constructed around that aircraft at its position, Pilot/Controller Glossary according to the trajectory associated with the aircraft’s Current Plan. CONFORMANCE REGION. A volume, bounded laterally, vertically, and longitudinally, within which an aircraft must be at a given time in order to be in conformance with the Current Plan Trajectory for that aircraft. At a given time, the conformance region is determined by the simultaneous application of the lateral, vertical, and longitudinal conformance bounds for the aircraft at the position defined by time and aircraft’s trajectory. CONSOLAN. A low frequency, long-distance NAVAID used principally for transoceanic naviga-tions. CONTACT. a.Establish communication with (followed by the name of the facility and, if appropriate, the frequency to be used). b.A flight condition wherein the pilot ascertains the attitude of his/her aircraft and navigates by visual reference to the surface. (See CONTACT APPROACH.)(See RADAR CONTACT.)CONTACT APPROACH. An approach wherein an aircraft on an IFR flight plan, having an air traffic control authorization, operating clear of clouds with at least 1 mile flight visibility and a reasonable expectation of continuing to the destination airport in those conditions, may deviate from the instrument approach procedure and proceed to the destination airport by visual reference to the surface. This approach will only be authorized when requested by the pilot and the reported ground visibility at the destination airport is at least 1 statute mile. (Refer to AIM.)CONTAMINATED RUNWAY. 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 contami-nated 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 fails 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 U.S.. The 48 adjoining States and the District of Columbia. PCG C.5 CONTINENTAL UNITED STATES. The 49 States located on the continent of North America and the District of Columbia. CONTINUE. When used as a control instruction should be followed by another word or words clarifying what is expected of the pilot. Example: “continue taxi,” “continue descent,” “continue inbound,” etc. CONTROL AREA [ICAO]. A controlled airspace extending upwards from a specified limit above the earth. CONTROL SECTOR. 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 frequen-cies assigned to the sector. |
