Is there a tool to plot locations within X nm of a position? I'm looking for a tool to allow me to see what is within X nms or X hrs of my base airport. Is there such a thing?  I remember a small airport I flew to once had a large map with a string attached to a pin located at the airports location on the map.  There were concentric rings from the location stating 100/200/300....nm. I'm basically looking for something like that such that I could explore and look for locations that are off my normal radar of places I would typically visit.  I typically use landings.com for baseline flight planning but you need an origin and destination. It doesn't look like it allows what I'm asking for. 

I'd even be happy if there was a hack for google maps etc. to do what I'm asking.
At least a couple of tools exist to search for airports beyond a certain distance from your departure point. You didn’t specify, so I will use mine: KHUA.

Using gcmap.com, search for near:KHUA beyond:50nm within:70nm to get a list of airports in the specified range.

To plot some of them on a map, place a few of those in a comma-separated list, e.g., KHUA,KGAD,KBHM,KSYI,KBNA,KAYX,M22,TN50,KJFX,KMRC,KAPT,KPYP,1M4,M22, and select the Map tool. Plot range rings with one or more lines in the Ranges box under Map Controls. I used


  50nm@KHUA
  70nm@KHUA
