In this Bold Method article (http://www.boldmethod.com/learn-to-fly/airspace/class-g-airspace/) it is stated that anything beyond the hard lines of this examples 1,200 ft AGL Class E (blue) transition area is Class G (Golf).

So far so good.

Class G Airspace

However, further down in the article, it is stated that beyond the hard lines of the magenta 700 ft AGL Class E transition area that the airspace is Class G until 1,200 ft AGL at which point it turns into Class E again (think the blue Class E area that exists above this entire area).

Class G Airspace

Why is it assumed that outside the 700 ft AGL Class E transition area there lies 1,200 ft AGL Class E? It surely isn't represented in the screenshot. Couldn't it just as well be Class G until 14,500 ft AGL?

Take a look at the legend on the side of a VFR chart. (You can get them for free at https://www.faa.gov/air_traffic/flight_info/aeronav/digital_products/vfr/ )

Class E exists at 1200' AGL unless otherwise designated as shown above.

  • I don't know why I didn't bother to re-read the legend, thank you for the answer. This legend however indicates that the magenta Class E doesn't necessarily have to be against a 1,200 ft. AGL Class E. It is possible to be against Class G. Do you know of any examples where this situation can be found? – Ryan Griffith Jan 19 '17 at 13:13
  • Even though I’ve read the legend hundreds of times, I missed it as well until you asked the question. – JScarry Jan 19 '17 at 14:44

    There are actually only a handful of places in the us where the 14,500 Class G exists. Check out http://aviation.stackexchange.com/q/29523/8730 – TomMcW Jan 19 '17 at 19:09
  • If you are bored sometime, try to figure out all of the different floors and ceilings of Class G around Death Valley and the Saline MOA. – JScarry Jan 19 '17 at 20:54

    So does anyone know any examples where the 700' Class E floor actually does laterally abut against class G airspace, as depicted as a possibility on the chart legend in this answer? – quiet flyer May 04 '19 at 19:38
