Plus/minus sign on planview
Posted: Tue Feb 21, 2017 12:32 pm
What does the + - sign next to certain obstacles denote on FAA approach plates (image attached)? Not sure how I have never noticed (or maybe I've just been glancing over them and treating them as normal MSL altitudes for obstructions), but for some reason it just popped out at me today. Went through the legend and Googled away, but can't seem to find an answer.
Thanks!
