How do I interpret the description for Class E airspace as shown on the Maps page pop-up?

When viewing class E airspace information on the Maps page, you may see text that you are not sure how to interpret.  The format for how Class E information is presented in the app as follows:  

     Flight Standards Region name, State, Class E airspace abbreviation, closest airport name, airspace altitudes, class of airspace.  

Flight Standards Regions are named and located as shown in image 1.

Class E airspace abbreviations will be shown as either E2, E3, or E5.  E2 is a Class E step down from the surface to 17,999’ MSL.  E3 is airspace that is used as an arrival extension to a Class C surface area. E5 as a Class E step down from 700’ AGL – 17,999’ MSL.

Here is an example to help clarify further.  Near Georgetown, Texas (KGTU), you can find the following Class E information:

     ASW, TX, E5 GEORGETOWN 700'-18000'MSL, Class E.
