Climb Gradient Question

[flyer07]

Does anyone know of an easy way to figure a required net climb gradient from SID charts? I know on the Jepp plates there are the tables that convert a required climb gradient in ft/nm to ft/min based on different aircraft groundspeeds, but a lot of turbojet aircraft performance charts only give the aircraft's net climb gradients as a percentage (i.e. Second Segment Takeoff Net Climb Gradient is found to be 1.6%). I am wondering if anyone has a shortcut method for calculating a required climb gradient from the SID charts as an expression of a certain percentage.

Thanks!

quick and easy: divide by 6000. 200ft/nm climb gradient
/6000=.33 or 3.3%

Thanks a bunch!

or another way ground speed x climb grad/60

If you use Jepps you can look under the 100 knot column of the table and add a decimal and it will give you the gradient. IE 650=6.5%.
