What runway has the steepest climb-out requirement upon take off?
This would probably be due to the need to avoid some natural obstacle, such as a mountain.

OBSTACLE CLEARANCE -
RWY 09: Maintain minimum 6.76% climb gradient to 275 (258).
RWY 27: Maintain minimum 7.20% climb gradient to 1102 (1085).
(Where the first number is altitude in feet and the second number is AAL, above aerodrome level)
