Hi folks, as I have recently focused on coding some procedures, I found something interesting. Give a look at `VHHH` `BEK01D` `10-3D`, the CF leg required 4 things related to crs and dist. Theta, Rho, MagCrs, Dist. For the first two parts, it’s 274.3 degrees and 31NM from `TD` VOR. BUT, for the last two parts, it’s **mysterious**. `2540` is 254 degrees, which is the runway course, and it makes sense. For `0090`, which means **9NM** , it makes no sense. I measured from the waypoint to both sides of the runway, none of them matched. As I drew a 9 NM circle from HH421, it bearly reached the runway. See Pic1.
