Hi,

Not sure if I have missed something completely or an error.

This question refers to finding the departure point of the N48 003E / N48 002W

I used the departure formula to calculate.

5 degree change x 60 = 300NM

Then 300 NM x cos .48

My answer of 300 was incorrect however in the answer workings the method uses 300 NM x .67 = 200

My question is where does the x.67 come from as I thought you use the Cosine of the latitude as part of the formula.

Any feedback welcome.

Thanks
