I am looking at the following question and though that all you needed to do to calculate the gradient of a runway was take the difference in height between both runway ends and divide it by the runway length x 100.

"The runway elevation of runway 05 is 299ft. At the other end of the 1200m runway, the threshold elevation of runway 23 is 363 ft. What is the gradient of runway 05?"

Difference in height is = 363 - 299=>64 feet

(64/1200) x 100=>5.33%

The example answer i am looking at in the book is 1.64%.

I wanted to check if I am doing something wrong.

Cheers,

Ross

Convert Meters into Feet first.   :-)

1200 meters = "x" ft.

Gradient = 64/"x" = 1.64.

Do the calculation yourself. ;-)
