When you are in the AirMap app and you see a circle with a checkerboard pattern, what does the number with a red line over it represent.  For example 30 with red line above it.  Does that mean stay below 30 meters or 30 feet or 300 feet or what???

Sounds like you're near an airport or some where restricted. For example, near Port Angeles (WA) where I was planning on flying last week then checked Airmap, I noticed the number and red line above it too. 0 means you can NOT fly where as other numbers mean to stay below that in feet. So when I see 100 or 200, then when I apply for FAA waiver then you need to stay below 100 or 200 feet.



BTW if you want to see this from a pilot planning perspective, you can view the Terminal Area Chart (TAC) here which is located near Seattle.

You can also get this for your area/state if you scroll/zoom out and view the World VFR version

Are you sure those aren't meters instead of feet???  In my case I'm looking at 30...doesn't make sense to have a 30 foot restriction.

Did you check your Settings and set it to Imperial?  Its possible your preference is on Metric.
