3Courchevel Airport I believe is the steepest public-use runway with an 18.6% grade. Operating in that airport requires a special endorsement and training. – Ron Beyer Jan 16 '17 at 17:29

4What country? What type of aircraft and operators? If there's no regulatory limit, there's probably a practical limit but it would depend on those details. – fooot Jan 16 '17 at 18:13

I think that's left up the pilot's discretion. – Romeo_4808N Jan 17 '17 at 04:41

I'm not completely sure what you're asking, but this question might be helpful – Pondlife Sep 15 '18 at 22:47

Most Part-25 certified aircraft have an operating limit of roughly +/-2% for runway slope, as most of the runways fall into this category.
It would be probably possible to certify aircraft for steeper slopes, however at a significant cost, as the flight test program would have to be extended to collect sufficient data.
It is also worth mentioning that anything over 1% upslope requires a bit of a different flare technique as opposed to a flat runway. Usually a bit earlier flare with a bit late thrust reduction does the trick. Extending the limit beyond 2% would probably require additional training, as the flare characteristics would be significantly different than that at a normal runway.

2Well, it is certainly possible to certify aircraft for steeper slopes, and some of them are, because there are places like VNLK (Hillary Tenzing Airport, Lukla, 12% slope) and LFLJ (Courchevel Altiport, over 18% slope). – Jan Hudec Sep 16 '18 at 20:56
