RWY 11 TORA 2300 ELEV 110M SLOPE -0.33
RWY 29 TORA 2800 ELEV 103M SLOPE +0.27
This is taken from a database which uses the difference in runway end elevation divided by length to get the slope. As its not one of our regular airports, no one has actually walked the runway. Maybe this airport proves that the concept of just using runway ends isn't always the correct approach.
