Pilot/Controller Glossary 

6/17/21 

designed to expedite aircraft turning off the runway 
after landing, thus reducing runway occupancy time. 

HIGH SPEED TURNOFF

 

(See HIGH SPEED TAXIWAY.) 

HIGH UPDATE RATE SURVEILLANCE– A 
surveillance system that provides a sensor update rate 
of less than 4.8 seconds. 

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.) 

HOLD­SHORT 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. 

HOLD­SHORT POSITION LIGHTS

 Flashing 

in­pavement white lights located at specified 
hold­short points. 

HOLD­SHORT POSITION MARKING

 The 

painted runway marking located at the hold­short 
point on all LAHSO runways. 

HOLD­SHORT POSITION SIGNS

 Red and white 

holding position signs located alongside the 
hold­short point. 

HOMING

  Flight toward a NAVAID, without 

correcting for wind, by adjusting the aircraft heading 
to maintain a relative bearing of zero degrees. 

(See BEARING.) 
(See ICAO term HOMING.) 

HOMING [ICAO]

  The procedure of using the 

direction­finding equipment of one radio station with 
the emission of another radio station, where at least 
one of the stations is mobile, and whereby the mobile 
station proceeds continuously towards the other 
station. 

HOVER CHECK

 Used to describe when a 

helicopter/VTOL aircraft requires a stabilized hover 
to conduct a performance/power check prior to hover 
taxi, air taxi, or takeoff. Altitude of the hover will 
vary based on the purpose of the check. 

HOVER TAXI

 Used to describe a helicopter/VTOL 

aircraft movement conducted above the surface and 
in ground effect at airspeeds less than approximately 
20 knots. The actual height may vary, and some 
helicopters may require hover taxi above 25 feet AGL 
to reduce ground effect turbulence or provide 
clearance for cargo slingloads. 

(See AIR TAXI.) 
(See HOVER CHECK.)
