I agree
oldebloke; there are some runway conditions for which a landing should not be attempted.
From Transport Canada report TP 14273E
On a smooth, wet concrete runway surface close to the minimum maintenance standard, the Falcon 20 tire-to-ground effective braking coefficient was found to be less than the aircraft certification requirement for a fully modulating anti-skid system. Based on this finding, the current operational dispatch factor of 1.92 for turbojet aircraft landing on wet runways at destination or alternate airports would have to be increased to a value of 2.2 to 2.4 in order to achieve the same level of safety as that which is currently accepted for dry runway operations.
So far this year there have been at least 10 large / commercial aircraft runway overruns; presumable these were using runway performance calculated with factors of 1.92. Thus if you encounter a ‘slippery’ runway – and in reality neither you or ATC can reliably detect this, then you will probably wish you had used factors of 2.2 or 2.4 as you slip off the end of the runway.
