AerodromeRunwayState
AerodromeRunwayState
An aggregation of runway conditions typically reported together at an aerodrome, including the runway contamination, friction, and deposits.
Properties | Definition | Type |
---|---|---|
allRunways | When true, indicates the reported conditions apply to all runways | Boolean |
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%. See WMO No. 306: - WMO Code table 0519 - BUFR Code table 0 20 087 | RunwayContamination |
depositType | The type of runway deposit, such as damp conditions, wet snow, or ice. WMO 306: Table 0919 | RunwayDeposits |
depthOfDeposit | Depth of deposit on the surface of the runway. Measured depth of deposit shall be given in millimeters (mm"). See WMO No. 306 WMO Code table 1079." | DistanceWithNilReason |
estimatedSurfaceFrictionOrBrakingAction | The estimated surface friction or braking action for the affected runway. When braking conditions are not reported and/or the runway is not operational estimatedSurfaceFrictionOrBrakingAction will not be reported. WMO 306: Table 0366 | RunwayFrictionCoefficient |
fromPreviousReport | When true, indicates a new runway state report is not available in time for dissemination of the METAR message and the previous runway state report is being repeated | Boolean |
runway | The runway to which the conditions apply. The runway may be missing in cases where all runways are closed due to snow | RunwayDirection |
