PCG H−2

HIGH FREQUENCY COMMUNICATIONS− High

radio frequencies (HF) between 3 and 30 MHz used

for air-to-ground voice communication in overseas

operations.

HIGH SPEED EXIT−

(See HIGH SPEED TAXIWAY.)

HIGH SPEED TAXIWAY− A long radius taxiway

designed and provided with lighting or marking to

define the path of aircraft, traveling at high speed (up

to 60 knots), from the runway center to a point on the

center of a taxiway. Also referred to as long radius

exit or turn-off taxiway. The high speed taxiway is

designed to expedite aircraft turning off the runway

after landing, thus reducing runway occupancy time.

HIGH SPEED TURNOFF−

(See HIGH SPEED TAXIWAY.)

HIWAS−

(See HAZARDOUS INFLIGHT WEATHER

ADVISORY SERVICE.)

HIWAS AREA−

(See HAZARDOUS INFLIGHT WEATHER

ADVISORY SERVICE.)

HIWAS BROADCAST AREA− A geographical area

of responsibility including one or more HIWAS

outlet areas assigned to a FSS for hazardous weather

advisory broadcasting.

HIWAS OUTLET AREA− An area defined as a 150

NM radius of a HIWAS outlet, expanded as necessary

to provide coverage.

HOLD FOR RELEASE− Used by ATC to delay an

aircraft for traffic management reasons; i.e., weather,

traffic volume, etc. Hold for release instructions

(including departure delay information) are used to

inform a pilot or a controller (either directly or

through an authorized relay) that an IFR departure

clearance is not valid until a release time or additional

instructions have been received.

(See ICAO term HOLDING POINT.)

HOLD IN LIEU OF PROCEDURE TURN− A hold

in lieu of procedure turn shall be established over a

final or intermediate fix when an approach can be

made from a properly aligned holding pattern. The

hold in lieu of procedure turn permits the pilot to

align with the final or intermediate segment of the

approach and/or descend in the holding pattern to an

altitude that will permit a normal descent to the final

approach fix altitude. The hold in lieu of procedure

turn is a required maneuver (the same as a procedure

turn) unless the aircraft is being radar vectored to the

final approach course, when “NoPT” is shown on the

approach chart, or when the pilot requests or the

controller advises the pilot to make a “straight−in”

approach.

HOLD PROCEDURE− A predetermined maneuver

which keeps aircraft within a specified airspace while

awaiting further clearance from air traffic control.

Also used during ground operations to keep aircraft

within a specified area or at a specified point while

awaiting further clearance from air traffic control.

(See HOLDING FIX.)
(Refer to AIM.)

HOLDING FIX− A specified fix identifiable to a

pilot by NAVAIDs or visual reference to the ground

used as a reference point in establishing and

maintaining the 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 of

which the position of an aircraft in flight is

maintained in accordance with air traffic control

clearances.

HOLDING PROCEDURE−

(See HOLD PROCEDURE.)

HOLD-SHORT POINT− A point on the runway

beyond which a landing aircraft with a LAHSO

clearance is not authorized to proceed. This point

may be located prior to an intersecting runway,

taxiway, predetermined point, or approach/departure

flight path.

HOLD-SHORT POSITION LIGHTS− Flashing

in-pavement white lights located at specified

hold-short points.

HOLD-SHORT POSITION MARKING− The

painted runway marking located at the hold-short

point on all LAHSO runways.

HOLD-SHORT POSITION SIGNS− Red and white

holding position signs located alongside the

hold-short point.
