Hi Pilots,

I am having trouble calculating heading and ground speed using my CR-3 and looking for some help.

Example Question: calculate heading and gs when:
Track: 135
TAS: 160
Wind (M): 240/20

Thanks in advance for your help!

Daniel.

Hi Daniel,

There are full instructions on how to use the CR3 available here:
www.jeppesen.com/download/misc/crinstructions.pdf

Also, there was a discussion about using the CR3 quite a while ago now, where we discussed how to use the CR3 to solve HDG and GS porblems. Take a look and see if that helps. If not, post again and we'll see what we can do.
