Are the figures obtained after 40% (wet) and 300% (contaminated) addition to the landing distance required for a dry R/W, considering using full brakes, auto brakes, spoilers and reversers?
If the R/W was actually contaminated, and not wet as reported to the pilot, wouldn't that be considered as a big safety hazard, since the difference between the distances required to stop the a/c on a wet and contaminated R/W is significant (9600 feet in the above example) ?
What is the most appropriate / recommended plan of action in this case.
Also, in the above example, if the R/W was reported as contaminated, the a/c would require 18,000 feet to bring it to stop. If the ALD was lower than this figure, the only obvious decision would be to fly to the alternate, correct?
