Runway Micro Texture

According to EASA Annual Safety Review 2021, runway excursion is one of the main key safety risk areas for commercial air transport (CAT), business aviation and non-commercial operations with complex motor-powered aircraft (NCC). There is currently a trend of aeroplane overruns on wet runways in which the achieved braking performance was worse than that specified in accordance with CS 25.109. The outcome of the research project will enable EASA to:

  • initiate rulemaking action to revise Regulation (EU) No 139/2014 as regards aerodromes in order to establish micro-texture threshold values, below which a runway would be considered as slippery wet and maintenance actions are required;
  • establish clear criteria for the development of a trend monitoring programme of runway surface; and
  • review the certification specifications regarding runway surface construction.
