The difference is in the TAN calculation. On a calculator, if I input 3 TAN, I end up with your answer of 2128.

Using the TAN function in Excel, which needs the angle in radians, you get 2182.

Interesting!


Not yet. Other countries have had Distance/Altitude charts for decades but hey, what would they know. Maybe that's why SW tries to land 5nm short...
Thank you for your reply.
The number 57.2 that you are using after TAN represents what exactly?
