Knowledge
Elements related to the pilot’s responsibilities, and the environmental, operational, and meteorological factors that affect landing from a precision approach.
Approach lighting systems and runway and taxiway signs, markings, and lighting.
Risk Management
Selection of an approach procedure and runway based on aircraft limitations, available distance, surface conditions, and wind.
Wake turbulence.
Collision hazards.
Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).
Distractions, task prioritization, loss of situational awareness, or disorientation.
Attempting to land from an unstable approach.
Flying below the glidepath.
Transitioning from instrument to visual references for landing.
Missed Approach.
Land and hold short operations (LAHSO). 44
Skill
Maintain the desired airspeed, ±5 knots, and vertical and lateral guidance within ¼-scale deflection of the indicators during the descent from DA/DH to a point where visual maneuvering is used to accomplish a normal landing.
Adhere to all ATC or evaluator advisories, such as NOTAMs, windshear, wake turbulence, runway surface, braking conditions, and other operational considerations.
Coordinate with crew, if applicable, and complete the appropriate checklist(s) in a timely manner.
Touch down at the aiming point markings, -250/+500 feet, or where there are no runway aiming point markings, 750 to 1,500 feet, from the approach threshold of the runway.
Maintain positive airplane control throughout the landing using drag and braking devices, as appropriate, to come to a stop.
Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.
Use runway incursion avoidance procedures, if applicable.
