Can't say that I can bring to mind any circumstance in which stopway would be longer than clearway .. do you have any examples you can cite ?
Actually, no. I think it's (like most of these things) theoretical.
Keep in mind that, just because the airport authority gives you various values for distances... your particular aircraft will not be able to use all the distance for each measure .. one will end up being limiting for the particular calculation.
Point taken, sir. Quite an interesting reading about the test pilots.
