Pilot/Controller Glossary 8/5/04CENTRAL EAST PACIFIC− An organized routesystem between the U.S. West Coast and Hawaii.CEP−(See CENTRAL EAST PACIFIC.)CERAP−(See COMBINED CENTER-RAPCON.)CERTIFIED TOWER RADAR DISPLAY (CTRD)−A radar display that provides a presentation ofprimary, beacon radar videos, and alphanumeric datafrom an Air Traffic Control radar system, which iscertified by the FAA to provide radar services.Examples include Digital Bright Radar IndicatorTower Equipment (DBRITE), Tower DisplayWorkstation (TDW) and BRITE.CFR−(See CALL FOR RELEASE.)CHAFF− Thin, narrow metallic reflectors of variouslengths and frequency responses, used to reflect radarenergy. These reflectors when dropped from aircraftand allowed to drift downward result in large targetson the radar display.CHARTED VFR FLYWAYS− Charted VFR Flywaysare flight paths recommended for use to bypassareas heavily traversed by large turbine-poweredaircraft. Pilot compliance with recommended flywaysand associated altitudes is strictly voluntary.VFR Flyway Planning charts are published on theback of existing VFR Terminal Area charts.CHARTED VISUAL FLIGHT PROCEDURE AP-PROACH− An approach conducted while operatingon an instrument flight rules (IFR) flight plan whichauthorizes the pilot of an aircraft to proceed visuallyand clear of clouds to the airport via visual landmarksand other information depicted on a charted visualflight procedure. This approach must be authorizedand under the control of the appropriate air trafficcontrol facility. Weather minimums required aredepicted on the chart.CHASE− An aircraft flown in proximity to anotheraircraft normally to observe its performance duringtraining or testing.CHASE AIRCRAFT−(See CHASE.)CIRCLE-TO-LAND MANEUVER− A maneuverinitiated by the pilot to align the aircraft with arunway for landing when a straight-in landing froman instrument approach is not possible or is notdesirable. At tower controlled airports, this maneuveris made only after ATC authorization has beenobtained and the pilot has established required visualreference to the airport.(See CIRCLE TO RUNWAY.)(See LANDING MINIMUMS.)(Refer to AIM.)CIRCLE TO RUNWAY (RUNWAY NUMBER)−Used by ATC to inform the pilot that he/she mustcircle to land because the runway in use is other thanthe runway aligned with the instrument approachprocedure. When the direction of the circling maneuverin relation to the airport/runway is required, thecontroller will state the direction (eight cardinalcompass points) and specify a left or right downwindor base leg as appropriate; e.g., “Cleared VORRunway Three Six Approach circle to Runway TwoTwo,” or “Circle northwest of the airport for a rightdownwind to Runway Two Two.”(See CIRCLE-TO-LAND MANEUVER.)(See LANDING MINIMUMS.)(Refer to AIM.)CIRCLING APPROACH−(See CIRCLE-TO-LAND MANEUVER.)CIRCLING MANEUVER−(See CIRCLE-TO-LAND MANEUVER.)CIRCLING MINIMA−(See LANDING MINIMUMS.)CLASS A AIRSPACE−(See CONTROLLED AIRSPACE.)CLASS B AIRSPACE−(See CONTROLLED AIRSPACE.)CLASS C AIRSPACE−(See CONTROLLED AIRSPACE.)CLASS D AIRSPACE−(See CONTROLLED AIRSPACE.)CLASS E AIRSPACE−(See CONTROLLED AIRSPACE.)CLASS G AIRSPACE− That airspace not designatedas Class A, B, C, D or E.CLEAR AIR TURBULENCE (CAT)− Turbulenceencountered in air where no clouds are present.
