A taxiing aircraft, which is approaching arunway, is clear of the runway when all parts of theaircraft are held short of the applicable holdingposition marking.b. A pilot or controller may consider an aircraft,which is exiting or crossing a runway, to be clear ofthe runway when all parts of the aircraft are beyondthe runway edge and there is no ATC restriction to itscontinued movement beyond the applicable holdingposition marking.c. Pilots and controllers shall exercise good judgementto ensure that adequate separation existsbetween all aircraft on runways and taxiways atairports with inadequate runway edge lines orholding position markings.CLEARANCE−(See AIR TRAFFIC CLEARANCE.)CLEARANCE LIMIT− The fix, point, or location towhich an aircraft is cleared when issued an air trafficclearance.(See ICAO term CLEARANCE LIMIT.)CLEARANCE LIMIT [ICAO]− The point of whichan aircraft is granted an air traffic control clearance.CLEARANCE VOID IF NOT OFF BY (TIME)−Used by ATC to advise an aircraft that the departureclearance is automatically canceled if takeoff is notmade prior to a specified time. The pilot must obtaina new clearance or cancel his/her IFR flight plan if notoff by the specified time.(See ICAO term CLEARANCE VOID TIME.)CLEARANCE VOID TIME [ICAO]− A time specifiedby an air traffic control unit at which a clearanceceases to be valid unless the aircraft concerned hasalready taken action to comply therewith.CLEARED APPROACH− ATC authorization for anaircraft to execute any standard or special instrumentapproach procedure for that airport.

It is predicated on known traffic andknown physical airport conditions.CLEARWAY− An area beyond the takeoff runwayunder the control of airport authorities within whichterrain or fixed obstacles may not extend abovespecified limits. These areas may be required forcertain turbine-powered operations and the size andupward slope of the clearway will differ depending onwhen the aircraft was certificated.(Refer to 14 CFR Part 1.)PCG C−3
