Also referred to as long radiusexit or turn-off taxiway. The high speed taxiway isdesigned to expedite aircraft turning off the runwayafter landing, thus reducing runway occupancy time.HIGH SPEED TURNOFF−(See HIGH SPEED TAXIWAY.)HIWAS−(See HAZARDOUS INFLIGHT WEATHERADVISORY SERVICE.)HIWAS AREA−(See HAZARDOUS INFLIGHT WEATHERADVISORY SERVICE.)HIWAS BROADCAST AREA− A geographical areaof responsibility including one or more HIWASoutlet areas assigned to an AFSS/FSS for hazardousweather advisory broadcasting.HIWAS OUTLET AREA− An area defined as a 150NM radius of a HIWAS outlet, expanded as necessaryto provide coverage.HOLD FOR RELEASE− Used by ATC to delay anaircraft for traffic management reasons; i.e., weather,traffic volume, etc. Hold for release instructions(including departure delay information) are used toinform a pilot or a controller (either directly orthrough an authorized relay) that an IFR departureclearance is not valid until a release time or additionalinstructions have been received.(See ICAO term HOLDING POINT.)HOLD PROCEDURE− A predetermined maneuverwhich keeps aircraft within a specified airspace whileawaiting further clearance from air traffic control.Also used during ground operations to keep aircraftwithin a specified area or at a specified point whileawaiting further clearance from air traffic control.(See HOLDING FIX.)(Refer to AIM.)HOLDING FIX− A specified fix identifiable to apilot by NAVAIDs or visual reference to the groundused as a reference point in establishing and maintainingthe position of an aircraft while holding.(See FIX.)(See VISUAL HOLDING.)(Refer to AIM.)HOLDING POINT [ICAO]− A specified location,identified by visual or other means, in the vicinity ofwhich the position of an aircraft in flight is maintainedin accordance with air traffic control clearances.HOLDING PROCEDURE−(See HOLD PROCEDURE.)HOLD-SHORT POINT− A point on the runwaybeyond which a landing aircraft with a LAHSOclearance is not authorized to proceed.
