Name | Data Type | Definition | ||
---|---|---|---|---|
section | CodeRunwaySectionType | Indicates the part of the runway that is affected. This attribute supports the current SNOWTAM practice, which consists in reporting the contamination information on each third of the runway length, starting from the threshold of the runway direction having the lower designation number. | ||
observationTime | DateTimeType | The date and time of the measurement completion (UTC). | Inherited from SurfaceContamination | |
depth | ValDepthType | The depth of the contamination on the surface. | Inherited from SurfaceContamination | |
frictionCoefficient | ValFrictionType | The average friction coefficient. | Inherited from SurfaceContamination | |
frictionEstimation | CodeFrictionEstimateType | A qualitative estimate of the friction. | Inherited from SurfaceContamination | |
frictionDevice | CodeFrictionDeviceType | The type of equipment used to determine the reported friction coefficient. | Inherited from SurfaceContamination | |
obscuredLights | CodeYesNoType | Indicates that the surface lights are obscured. | Inherited from SurfaceContamination | |
furtherClearanceTime | TimeType | The date and time (UTC) when it is expected to complete further clearance. | Inherited from SurfaceContamination | |
furtherTotalClearance | CodeYesNoType | Indicates that the further total clearance is expected. | Inherited from SurfaceContamination | |
nextObservationTime | DateTimeType | The date and time of the next intended measurement report (UTC). | Inherited from SurfaceContamination | |
proportion | ValPercentType | The percentage of the contaminated area from the overall extent of the surface. | Inherited from SurfaceContamination |
