Calibrated Airspeed

How to calculate calibrated Airspeed using E6B? To do this, you need to get Outside air temperature OAT from the metars, determine your True Airspeed from your performance section of your Pilot Operating handbook POH and finally, you need your pressure altitude of your planned cruise altitude for the leg.

Using the E6B
You can compute your your CAS,

You can also use your CX2/CX3 to determine your CAS.

I also add in the last section of the video, hoe to get your indicated Airspeed after calculating your CAS
