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.


1 Answer 1


The first one that came to mind is London City Airport (EGLC) which is world famous for its steep approaches, and for which I found these requirements on its departure charts:

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)
