CAT.OP.MPA.300 Approach and landing conditions

LANDING DISTANCE ASSESSMENT

(a)The in-flight landing distance assessment should be based on the latest available weather report and runway condition report (RCR) or equivalent information based on the RCR.

(b)The assessment should be initially carried out when the weather report and the RCR are obtained, usually around top of descent. If the planned duration of the flight does not allow the flight crew to carry out the assessment in non-critical phases of flight, the assessment should be carried out before departure.

(c)When meteorological conditions may lead to a degradation of the runway surface condition, the assessment should include consideration of how much deterioration in runway surface friction characteristics may be tolerated, so that a quick decision can be made prior to landing.

(d)The flight crew should monitor the evolution of the actual conditions during the approach, to ensure that they do not degrade below the condition that was previously determined to be the minimum acceptable.

WIND DATA The information on wind contained in METAR/SPECI/ATIS reports (average of a 10-minute period) should be the basis for the landing performance calculations, while instant wind information reported by the tower should be monitored during the approach to ensure that the wind speed does not exceed the assumptions made for landing performance calculations.
