Hi Guys,
I tried searching for this chart online for the whole evening but to no avail. Can some kind souls provide me with the URL or can email me directly a softcopy ?
Thank you very much.
Cheers,

Jeppesen has such a chart in their terminal legend pages. It's called "Gradient to Rate Table."

HI guys,
Thanks for the reply. In fact I was looking for the one where there's 3 vertical scales (G/S, Climb Gradient, Rate of Climb). We will have to use a ruler to join 2 components to determine the last.
Any luck with that ?
Thanks a lot.
Cheers

A simple rule of thumb is.
Climb rate = Gradient (%) x Groundspeed.
So for example if you want to achieve a 5% gradient at 180kts G/S you need to climb at 900 fpm.
Another one, if you need to change your altitude by xxx feet/mile multiply that by your speed in miles per minute and the answer is feet per minute.
feet/mile x miles/minute = feet/minute. Up or down.
e.g. you want to lose 3000' in 10nms or 300ft/nm at 180kts (3nm/minute) descend at 900fpm.
Is this any help?
Regards,
BH.
