Smash bugger, I never said that it is no big deal. All I am saying is that as far as I am concerned, as a commander you can make an informed decision. You have all the tools at your disposal to do so. Even if the last 1000 meters were blocked, that still would leave a 2100 meter runway to land on. That's well within the performance limitations of most jets I know.
Of course there are issues to discuss. I would not do this at night after an approach to limits for instance. The color coding for the runway lights are off. So there are lots of things to think about. So if you can find more issues, please let me know, I am happy to be corrected, I am honestly interested to know your reasonable objections.
Hypothetically speaking from the info on this thread some people would rather divert to a 1800m runway with a cliff at the end, than land on a 3100m runway with a little business jet sitting at the very end. Where is the logic in that?
Eric, thanks for the useful info!
