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.)
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.
LANDING DIRECTION INDICATOR− A device
which visually indicates the direction in which
landings and takeoffs should be made.
(See TETRAHEDRON.)
(Refer to AIM.)
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 established MDA or DH is
not authorized during an approach unless the
aircraft is in a position from which a normal
approach to the runway of intended landing can be
made and adequate visual reference to required
visual cues is maintained.
(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.)
LAST ASSIGNED ALTITUDE− The last altitude/
flight level assigned by ATC and acknowledged by
the pilot.
(See MAINTAIN.)
(Refer to 14 CFR Part 91.)
LATERAL NAVIGATION (LNAV)– A function of
area navigation (RNAV) equipment which calculates,
displays, and provides lateral guidance to a profile or
path.
LATERAL SEPARATION− The lateral spacing of
aircraft at the same altitude by requiring operation on
different routes or in different geographical locations.
(See SEPARATION.)

LIGHTED AIRPORT− An airport where runway and
obstruction lighting is available.
(See AIRPORT LIGHTING.)
(Refer to AIM.)
LIGHT GUN− A handheld directional light signaling
device which emits a brilliant narrow beam of white,
green, or red light as selected by the tower controller.
The color and type of light transmitted can be used to
approve or disapprove anticipated pilot actions where
radio communication is not available. The light gun
is used for controlling traffic operating in the vicinity
of the airport and on the airport movement area.
(Refer to AIM.)
LOCAL AIRPORT ADVISORY (LAA)− A service
provided by facilities, which are located on the
landing airport, have a discrete ground−to−air communication
frequency or the tower frequency when
the tower is closed, automated weather reporting with
voice broadcasting, and a continuous ASOS/AWOS
data display, other continuous direct reading instruments,
