Something to think about on final approach
By Stuart Clarke on 23 July, 2013

 As I noted in the previous entry about the findings of our airline safety review at the half-way point in 2013, runway excursions remain the most popular accident. No world region appears to be immune, although some are particularly good at it. A study published early this year by the Netherlands-based NLR Aviation Safety Institute reveals that the most common causal factor in runway excursions – whether overruns or veering off the side – is runway contamination, whether water, snow, slush or ice. Runway surface contamination is a factor in nearly 58% of all excursion. This is the bit to think about on approach: the NLR has worked out that if a runway is contaminated, the risk of a runway excursion is 13 times that of landing on a dry runway. The next thing to think about is how your approach is going: are you fast or high? Landing beyond the touchdown zone is a factor in 39% of overruns, and touching down too fast a contributor in 20% of cases. There are plenty of other significant factors, all charted in the NLR report: http://tinyurl.com/kn5n4r2 -
