AMC1 ADR.OPS.B.037(a);(b) Assessment of runway surface condition and assignment of runway condition code ED Decision 2021/003/R ASSIGNMENT OF RUNWAY CONDITION CODE (a) The aerodrome operator should: (1) assign a RWYCC 6, if 25 per cent or less area of a runway third is wet or covered by contaminant; (2) describe in the plain-language remarks part of the situational awareness section of the RCR the location of the area that is wet or covered by the contaminant, if the distribution of the contaminant is not uniform; (3) assign a RWYCC based on the contaminant that will most likely affect the aeroplane’s performance, if multiple contaminants are present and the total coverage is more than 25 per cent but no single contaminant covers more than 25 per cent of any runway third; (4) not upgrade an assigned RWYCC 5, 4, 3, or 2; and (5) not upgrade beyond RWYCC 3 an assigned RWYCC 1 or 0. (b) The aerodrome operator may upgrade an assigned RWYCC 1 or 0 when all available means of assessing runway slipperiness, including properly operated and calibrated measuring devices, if available, have been used to support the decision. (c) The aerodrome operator, when RWYCC 1 or 0 is upgraded, should assess the runway surface frequently during the period the higher RWYCC is in effect, to ensure that the runway surface condition does not deteriorate below the assigned code. (d) The aerodrome operator, if sand or other runway treatments are used to support upgrading of the RWYCC, should assess the runway surface frequently to ensure the continued effectiveness of the treatment. (e) The aerodrome operator should appropriately downgrade the RWYCC taking into consideration all available means of assessing runway slipperiness, including special air-reports. (f) The aerodrome operator, when the primary assignment of the RWYCC in accordance with RCAM does not reflect the prevailing conditions accurately, and is supported by other observations, experience and local knowledge, should downgrade or upgrade the RWYCC. In this case: (1) the RWYCC should be the downgraded or upgraded RWYCC following the overall assessment; (2) the description of the runway surface contaminant will reflect the actual condition; and (3) in the plain language remarks section of the RCR, the terms ‘UPGRADED’ or ‘DOWNGRADED’ should be used.
