Effective TAS on CR5 Computers

MaxCavill created the topic: Effective TAS on CR5 Computers

Hi again,

To determine Effective TAS on a CR5 style flight computer, how do you get the effective TAS? I am aware that ETAS = GS + W/C, but I dont know how to calculate the W/C on a CR5 to get the groundspeed to the ETAS value.

Thanks

First download the manual if you don't already have one - jeppesen.com/download/misc/crinstructions.pdf

Have a read through the wind side notes from page 31 and all will be revealed.
