Airspace Organisation USA
 

Could somebody please direct me to where I can find a relatively easy to absorb depiction of exactly which classes of airspace are where in the US? Hacking through the excellent FAA & NAR websites has intrigued me for hours, but I can't find a simple overview anywhere.

There are those who would have us adopt the US airspace system here in it's entirety (except for towers, radar and naviads) but I don't really know what we are buying??? <img src="tongue.gif" border="0">

You should look up the electronic version of the aeronautical information manual (AIM). They should have explanations as well as pictures in there. If worst comes to worse and you can't find it let me know. I will send you something. I will be out of town for a meeting all next week though.

Thankyou again Scott,

I have read again the sections that seem most relevant, and still have a few questions...

AIM says Class E airspace extends upward from a specified level where "Federal airway system is inadequate". Is this the step from 1200agl to 14,500amsl? Where is this step located? Is it determined by radio or radar coverage, or other factors?

The descriptions and diagram seems to indicate Class B, C & D airspace extend up to 10,000amsl, 4,000agl & 2,500agl respectively, with
Class E covering the gap up to Class A. Is that the way it is? What happens with such airspace under Class E with a base of 14,500amsl?

ICAO Annexe 11 says at the vertical boundary between 2 airspaces you provide the service applicable to the least restrictive, but 18,500amsl is shown as the boundary between Class E & A, but within Class A! Is this how it is?

Please forgive the detailed questions, I hope they have nice donuts at the meetings... <img src="smile.gif" border="0">

I wanna see a wedding cake!
