AerodromeRunwayState

AerodromeRunwayState

An aggregation of runway conditions typically reported together at an aerodrome, including the runway contamination, friction, and deposits.

cleared Indicates that reported runway has been cleared of meteorological deposits, such as snow. ICAO Annex 3 / WMO No. 49-2: CLRD" Section 4.8.1.5, Table A3-2 "State of the runway"" Boolean
contamination Proportion of runway surface that is contaminated - usually expressed as a percentage of the total runway area. WMO reporting procedures require that contamination is reported in the following categories: - less than 10%; - between 11% and 25%; - between 26% and 50%; and - more than 50%.
