designed to expedite aircraft turning off the runway HOLDING POINT [ICAO]− A specified location, after , thus reducing runway occupancy time. identified by visual or other means, in the vicinity of which the position of an aircraft in flight is HIGH SPEED TURNOFF− maintained in accordance with (See HIGH SPEED TAXIWAY.) clearances. HIGH UPDATE RATE SURVEILLANCE– A HOLDING PROCEDURE− surveillance system that provides a sensor update rate (See HOLD PROCEDURE.) of less than 4.8 seconds. HOLD-SHORT POINT− A point on the runway beyond which a landing aircraft with a LAHSO HOLD FOR RELEASE− Used by ATC to delay an clearance is not authorized to proceed. This point aircraft for traffic management reasons; i.e., weather, may be located prior to an intersecting runway, traffic volume, etc. Hold for release instructions taxiway, predetermined point, or approach/departure (including departure delay information) are used to flight path. inform a pilot or a controller (either directly or through an authorized relay) that an IFR departure HOLD-SHORT POSITION LIGHTS− Flashing clearance is not valid until a release time or additional in-pavement white lights located at specified instructions have been received. hold-short points. (See ICAO term HOLDING POINT.) HOLD-SHORT POSITION MARKING− The painted runway marking located at the hold-short HOLD−IN−LIEU OF PROCEDURE TURN− A point on all LAHSO runways. hold−in−lieu of procedure turn shall be established over a final or intermediate fix when an approach can HOLD-SHORT POSITION SIGNS− Red and white be made from a properly aligned holding pattern.

The hold−in−lieu of procedure (See BEARING.) turn is a required maneuver (the same as a procedure (See ICAO term HOMING.) turn) unless the aircraft is being radar vectored to the HOMING [ICAO]− The procedure of using the final approach course, when “NoPT” is shown on the direction-finding equipment of one radio station with approach chart, or when the pilot requests or the the emission of another radio station, where at least controller advises the pilot to make a “straight−in” one of the stations is mobile, and whereby the mobile approach. station proceeds continuously towards the other station. HOLD PROCEDURE− A predetermined maneuver which keeps aircraft within a specified airspace while HOVER CHECK− Used to describe when a awaiting further clearance from air traffic control. helicopter/VTOL aircraft requires a stabilized hover Also used during ground operations to keep aircraft to conduct a performance/power check prior to hover within a specified area or at a specified point while taxi, air taxi, or . Altitude of the hover will awaiting further clearance from air traffic control. vary based on the purpose of the check. (See HOLDING FIX.) HOVER TAXI− Used to describe a helicopter/VTOL (Refer to AIM.) aircraft movement conducted above the surface and in ground effect at airspeeds less than approximately HOLDING FIX− A specified fix identifiable to a 20 knots. The actual height may vary, and some pilot by NAVAIDs or visual reference to the ground helicopters may require hover taxi above 25 feet AGL used as a reference point in establishing and to reduce ground effect turbulence or provide maintaining the position of an aircraft while holding. clearance for cargo slingloads.
