Pilot/Controller Glossary  8/15/19  L  PCG L-1  LAA- (See LOCAL AIRPORT ADVISORY.)  LAAS- (See LOW ALTITUDE ALERT SYSTEM.)  LAHSO- An acronym for “Land and Hold Short  Operation.” These operations include landing and  holding short of an intersecting runway, a taxiway, a  predetermined point, or an approach/departure  flightpath.  LAHSO-DRY- Land and hold short operations on  runways that are dry.  LAHSO-WET- Land and hold short operations on  runways that are wet (but not contaminated).  LAND AND HOLD SHORT OPERATIONS- Operations which include simultaneous takeoffs and  landings and/or simultaneous landings when a  landing aircraft is able and is instructed by the  controller to hold-short of the intersecting runway/  taxiway or designated hold-short point. Pilots are  expected to promptly inform the controller if the hold  short clearance cannot be accepted.  (See PARALLEL RUNWAYS.)  (Refer to AIM.)  LAND-BASED AIR DEFENSE IDENTIFICA- TION ZONE (ADIZ)- An ADIZ over U.S.  metropolitan areas, which is activated and deactivat- ed as needed, with dimensions, activation dates, and  other relevant information disseminated via NO- TAM.  (See AIR DEFENSE IDENTIFICATION ZONE.)  LANDING AREA- Any locality either on land,  water, or structures, including airports/heliports and  intermediate landing fields, which is used, or  intended to be used, for the landing and takeoff of  aircraft whether or not facilities are provided for the  shelter, servicing, or for receiving or discharging  passengers or cargo.  (See ICAO term LANDING AREA.)  LANDING AREA [ICAO]- That part of a movement  area intended for the landing or take-off of aircraft.  (See MAINTAIN.)  (Refer to 14 CFR Part 91.)  LAST ASSIGNED ALTITUDE- The last altitude/  flight level assigned by ATC and acknowledged by  the pilot.  LANDING DIRECTION INDICATOR- A device  which visually indicates the direction in which  landings and takeoffs should be made.  LANDING DISTANCE AVAILABLE (LDA)- The  runway length declared available and suitable for a  landing airplane.  (See ICAO term LANDING DISTANCE  AVAILABLE.)  LANDING DISTANCE AVAILABLE [ICAO]- The  length of runway which is declared available and  suitable for the ground run of an aeroplane landing.  LANDING MINIMUMS- The minimum visibility  prescribed for landing a civil aircraft while using an  instrument approach procedure. The minimum  applies with other limitations set forth in 14 CFR  Part 91 with respect to the Minimum Descent  Altitude (MDA) or Decision Height (DH) prescribed  in the instrument approach procedures as follows:  a.  Straight-in landing minimums. A statement of  MDA and visibility, or DH and visibility, required for  a straight-in landing on a specified runway, or  b.  Circling minimums. A statement of MDA and  visibility required for the circle-to-land maneuver.  Note: Descent below the MDA or DH must meet the  conditions stated in 14 CFR Section 91.175.  (See CIRCLE-TO-LAND MANEUVER.)  (See DECISION HEIGHT.)  (See INSTRUMENT APPROACH  PROCEDURE.)  (See MINIMUM DESCENT ALTITUDE.)  (See STRAIGHT-IN LANDING.)  (See VISIBILITY.)  (Refer to 14 CFR Part 91.)  LANDING ROLL- The distance from the point of  touchdown to the point where the aircraft can be  brought to a stop or exit the runway.  LANDING SEQUENCE- The order in which  aircraft are positioned for landing.  (See APPROACH SEQUENCE.)  (See TETRAHEDRON.)  (Refer to AIM.)
