VOR chart help

Recommended Posts

Don't know where else to post this, so I figured someone here would know. Looking at the VOR RWY 15 into EPWA, in the bottom left is where it shows the MDA. It shows 2 categories, C and D. Now, the part I'm confused about, the box with the MDA has 2 rows. The top row is labeled,

"Ft-m/km" and the row below is "ft". And the numbers given are, "480-1.8" and below that "830". Now I'm assuming the 830 is the MDA. What does the 480-1.8 mean, I can't figure out what the ft-m/km indicates?

Not certain what chart source you're using, but the one I'm looking at (Polish Air Navigation Services Agency) doesn't have the MDA as you're describing. It's showing Cat A/B/C/D and two possible values one for Straight-In and the other for Circling.

You will have to ask them what their chart means.

1.8 means 1.8km visibility. 830ft is the MDA and 480 is MDH which is the cloud ceiling measured from the ground. Hence 478 (MDH) + 352 (Threshold elevation) = 830 which is the MDA

Yeah I figured that. I checked another chart and it has it as well. But when I look at charts from other sources it's not there. Thanks for helping!
