Here is a random spot i found with a class E4, i've also seen some E2 and E3 spots too. However the E4 in the picture is not as big as it is in my area and the circle that is connected to the E4 is a class D. Im sorry i don't know the correct terminology i'm fairly new to this kind of stuff.
Purely from a piloting standpoint it defines the area that you must either steer clear of or operate according to FAA rules for that airspace includes requirements for radio contact, IFF squawk (if required), and wx restrictions if VFR.
For you as a hobbyist it matters that you avoid or get clearance. As I noted earlier, if you get clearance you are good as long as you stick to their direction and restrictions - usually remain below 400' AGL and remain clear of approach and departure paths.
I cannot explain an E4 from an E3 so either someone that is familiar with AMA airspace categories might or I wouldn't worry about it one way or the other based on what I stated.
You could check with AMA to see what they mean by it. I've seen nothing in the FAA regs that defines airspace that way, not unless it's buried in the weeds, they just define each class and then altitude layers for different VFR wx, radio, and IFF requirements. |
