SE215: Runway Excursion - Landing Distance Assessment



The purpose of this Safety Enhancement is to improve flight crew awareness of their landing distance margin and the factors and variables that can affect it. Flight crews should assess landing performance based on conditions actually existing at time of arrival (rather than the conditions presumed at dispatch), including weather, runway conditions (using standardized terminology), aircraft weight, braking systems, and performance assumptions. To support this assessment, the following should be accomplished:

  1. Federal Aviation Administration (FAA) Flight Standards Service (AFS) develops guidance material incorporating Takeoff and Landing Performance Assessment (TALPA) Aviation Rulemaking Committee (ARC) recommendations addressing procedures for conducting a landing performance assessment using actual conditions existing at the time of arrival (including standardizing terms used to report conditions and make landing distance assessments).
  2. FAA Office of Airports (ARP) develops guidance material to define terms and format for reporting runway conditions and criteria for clearing or closing runways when friction levels degrade to a level where safe operations are not assured.
  3. FAA Aircraft Certification Service (AIR) develops guidance material for how manufacturers should provide airplane landing distance data consistent with TALPA recommendations, including for contaminated surfaces.
  4. FAA Air Traffic Organization (ATO) revises their procedures to allow controllers to report timely runway conditions to pilots using TALPA terminology.
  5. Airport operators incorporate the guidance material into their runway assessment procedures and report the runway conditions using the new terminology.
  6. Manufacturers provide a standardized set of landing distance performance data, which will support the new landing distance calculation standard as defined by guidance material.
  7. Air Carriers incorporate the guidance material and manufacturers’ landing standardized assessment data into standard operating procedures (SOP) and training to implement landing assessment at time of arrival.
