On a related note. Why the recent expensive publication teaching us all how to plan descents and do CDAs? Maybe some aren't as capable as they think they are would be my guess!
And the calculation was wrong, it's a typo...second example should have the task 42 miles to GI not 2 and the answer should be 12600 not 2600.
On the other note, is the new DCP Boieng actually.... an airbus guy?
