Public Boolean
  estimatedSurfaceFrictionUnreliable
Details:
sequenceNumber=3
xsdAsAttribute=true
Notes: When true, the estimated surface friction is unreliable and is not reported.#lt;br /#gt;#lt;/p#gt;#lt;p#gt;#lt;br /#gt;#lt;/p#gt;#lt;p#gt;WMO 306:#lt;br /#gt;#lt;/p#gt;#lt;p#gt;Table 0366#lt;br /#gt;#lt;/p#gt;
Public RunwayDirection
  runway
Details:
sequenceNumber=4
Notes: The runway to which the conditions apply.  The runway may be missing in cases where all runways are closed due to snow
Public RunwayDeposits
  depositType
Details:
sequenceNumber=5
Notes: The type of runway deposit, such as damp conditions, wet snow, or ice.#lt;br /#gt;#lt;/p#gt;#lt;p#gt;#lt;br /#gt;#lt;/p#gt;#lt;p#gt;WMO 306:#lt;br /#gt;#lt;/p#gt;#lt;p#gt;Table 0919#lt;br /#gt;#lt;/p#gt;
Public RunwayContamination
  contamination
Details:
quantity=http://codes.wmo.int/common/quantity-kind/runwayContaminationCoverage

Notes: Proportion of runway surface that is contaminated - usually expressed as a percentage of the total runway area.#lt;br /#gt;#lt;/p#gt;#lt;p#gt;#lt;br /#gt;#lt;/p#gt;#lt;p#gt;WMO reporting procedures require that contamination is reported in the following categories:#lt;br /#gt;#lt;/p#gt;#lt;p#gt;- less than 10%;#lt;br /#gt;#lt;/p#gt;#lt;p#gt;- between 11% and 25%;#lt;br /#gt;#lt;/p#gt;#lt;p#gt;- between 26% and 50%; and#lt;br /#gt;#lt;/p#gt;#lt;p#gt;- more than 50%. #lt;br /#gt;#lt;/p#gt;#lt;p#gt;#lt;br /#gt;#lt;/p#gt;#lt;p#gt;See WMO No. 306:#lt;br /#gt;#lt;/p#gt;#lt;p#gt;- WMO Code table 0519#lt;br /#gt;#lt;/p#gt;#lt;p#gt;- BUFR Code table 0 20 087#lt;br /#gt;#lt;/p#gt;

MeteorologicalAerodromeObservationRecord
Class   		Name:  
  		Name: runwayState
 
Details:
When runways are affected by snow, slush, or other contaminants, a runway state report for each runway in use is required.<br /></p><p><br /></p><p>There is no maximum number of runway states that can be reported.  This may be changed in a future amendment.<br /></p>
Constraint Type Status
if( estimatedSurfaceFriction != NULL ) estimatedSurfaceFriction > 0.0 AND estimatedSurfaceFriction <= 0.90 Invariant Approved
Details:
Estimated surface friction must  be between 0 and 0.9
if( estimatedSurfaceFrictionUnreliable == TRUE ) estimatedSurfaceFriction == NULL Invariant Approved
Details:
When surface friction is unreliable, no surface friction is reported
if( allRunways ) runway == NULL Invariant Approved
Details:
When all runways are being reported upon, no specific Runway should be reported
if( runway != NULL ) allRunways == NULL OR allRunways == FALSE Invariant Approved
Details:
When a single Runway is reported upon, the allRunways flag should be missing or false
