LAHSO at their destination airport. Pilots should
have, readily available, the published ALD and
runway slope information for all LAHSO runway
combinations at each airport of intended landing.
Additionally, knowledge about landing performance
data permits the pilot to readily determine that the
ALD for the assigned runway is sufficient for safe
LAHSO. As part of a pilot’s preflight planning
process, pilots should determine if their destination
airport has LAHSO. If so, their preflight planning
process should include an assessment of which
LAHSO combinations would work for them given
their aircraft’s required landing distance. Good pilot
decision−making is knowing in advance whether one
can accept a LAHSO clearance if offered.
22.2.5For those airplanes flown with two crewmembers,
effective intra−cockpit communication
between cockpit crewmembers is also critical. There
have been several instances where the pilot working
the radios accepted a LAHSO clearance but then
simply forgot to tell the pilot flying the aircraft.

22.2.6If, for any reason, such as difficulty in
discerning the location of a LAHSO intersection,
wind conditions, aircraft condition, etc., the pilot
elects to request to land on the full length of the
runway, to land on another runway, or to decline
LAHSO, a pilot is expected to promptly inform ATC,
ideally even before the clearance is issued. A
LAHSO clearance, once accepted, must be
adhered to, just as any other ATC clearance,
unless an amended clearance is obtained or an
emergency occurs. A LAHSO clearance does not
preclude a rejected landing.
22.2.7A pilot who accepts a LAHSO clearance
should land and exit the runway at the first convenient
taxiway (unless directed otherwise) before reaching
the hold short point. Otherwise, the pilot must stop
and hold at the hold short point. If a rejected landing
becomes necessary after accepting a LAHSO
clearance, the pilot should maintain safe separation
from other aircraft or vehicles, and should
promptly notify the controller.
22.2.8Controllers need a full read back of all
LAHSO clearances. Pilots should read back their
LAHSO clearance and include the words, HOLD
SHORT OF (RUNWAY/TAXIWAY/OR POINT)" in
their acknowledgment of all LAHSO clearances. In
order to reduce frequency congestion, pilots are
encouraged to read back the LAHSO clearance
without prompting. Don’t make the controller have to
ask for a read back!
22.3LAHSO Situational Awareness
22.3.1Situational awareness is vital to the success of
LAHSO. Situational awareness starts with having
current airport information in the cockpit, readily
accessible to the pilot. (An airport diagram assists
pilots in identifying their location on the airport, thus
reducing requests for progressive taxi instructions"
from controllers.)
22.3.2Situational awareness includes effective
pilot−controller radio communication. ATC expects
pilots to specifically acknowledge and read back all
LAHSO clearances as follows:
EXAMPLE−
ATC: (Aircraft ID) cleared to land runway six right, hold
short of taxiway bravo for crossing traffic (type aircraft)."
Aircraft: (Aircraft ID), wilco, cleared to land runway six
right to hold short of taxiway bravo."
ATC: (Aircraft ID) cross runway six right at taxiway
bravo, landing aircraft will hold short."
Aircraft: (Aircraft ID), wilco, cross runway six right at
bravo, landing traffic (type aircraft) to hold."
22.3.3Situational awareness also includes a thorough
understanding of the airport markings, signage,
and lighting associated with LAHSO. These visual
aids consist of a three−part system of yellow
hold−short markings, red and white signage and,
in certain cases, in−pavement lighting. Visual aids
assist the pilot in determining where to hold short.
FIG ENR 1.1−4, FIG ENR 1.1−5, FIG ENR 1.1−6
depict how these markings, signage, and lighting
combinations will appear once installed. Pilots are
cautioned that not all airports conducting LAHSO
have installed any or all of the above markings,
signage, or lighting.
22.3.4Pilots should only receive a LAHSO
clearance when there is a minimum ceiling of
1,000feet and 3 statute miles visibility. The intent of
having basic" VFR weather conditions is to allow
pilots to maintain visual contact with other aircraft
