I'm studying for my EASA PPL(A) exam, and for some questions for the Navigation exam, I'm requested to calculate the distance between two points, like so:
What is the distance from VOR Brünkendorf (BKD) (53°02?N, 011°33?E) to Pritzwalk (EDBU) (53°11'N, 12°11'E)?
A. 24 km
B. 42 NM
C. 24 NM <--- this is the correct answer
D. 42 km
I'm given also the following attached chart:
What's the best method to apply in order to calculate the distance? Should I apply a formula or "just" by looking at the chart?
