CHARTED VISUAL FLIGHT PROCEDURE APPROACH (P/CG) - An approach conducted while operating on an instrument flight rules (IFR) flight plan which authorizes the pilot of an aircraft to proceed visually and clear of clouds to the airport via visual landmarks and other information depicted on a charted visual flight procedure. This approach must be authorized and under the control of the appropriate air traffic control facility. Weather minimums required are depicted on the chart. CHASE/CHASE AIRCRAFT - An aircraft flown in proximity to another aircraft normally to observe its performance during training or testing. CIRCLE TO LAND MANEUVER/CIRCLING MANEUVER - A maneuver initiated by the pilot to align the aircraft with a runway for landing when a straight-in landing from an instrument approach is not possible or is not desirable. This maneuver is made only after Air Traffic Control authorization has been obtained and the pilot has established required visual reference to the airport. (See Circle to Runway, Landing Minimums) CIRCLE TO RUNWAY (RUNWAY NUMBERED) - Used by Air Traffic Control to inform the pilot that he must circle to land because the runway in use is other than the runway aligned with the instrument approach procedure. When the direction of the circling maneuver in relation to the airport/runway is required, the controller will state the direction (eight cardinal compass points) and specify a left or right downwind or base leg as appropriate; e.g., "Cleared VOR Runway 36 approach circle to Runway 22" or "Circle Northwest of the airport for a right downwind to Runway 22". (See Circle to Land maneuver, Landing Minimums) CIRCLING APPROACH - (See Circle-to-Land Maneuver) CIRCLING MINIMA - (See Landing Minimums) CLEAR-AIR TURBULENCE/CAT - Turbulence encountered in air where no clouds are present. This term is commonly applied to high-level turbulence associated with wind shear. CAT is often encountered in the vicinity of the jet stream. (See Wind Shear, Jet Stream) CLEARANCE - (See Air Traffic Clearance) CLEARANCE LIMIT (P/CG) - The fix, point, or location to which an aircraft is cleared when issued an air traffic clearance. CLEARANCE LIMIT (ICAO) - The point to which an aircraft is granted an Air Traffic Control clearance. CLEARANCE VOID IF NOT OFF BY (TIME) (P/CG) - Used by Air Traffic Control to advise an aircraft that the departure clearance is automatically cancelled if take-off is not made prior to a specified time. The pilot must obtain a new clearance or cancel his IFR flight plan if not off by the specified time. CLEARANCE VOID TIME (ICAO) - A time specified by an Air Traffic Control unit at which a clearance ceases to be valid unless the aircraft concerned has already taken action to comply therewith. CLEARED AS FILED - Means the aircraft is cleared to proceed in accordance with the route of flight filed in the flight plan. This clearance does not include the altitude, SID, or SID Transition.
