Number of Class D Airports

Asked by: 3882 views

I'm trying to find the total number of Class D airports in the whole of the USA and also a breakdown by State.  Anyone know where I could find that data?  The AIM shows Class B and C airports, but not D.  The FAA site is very hard to find anything in.

    All airspace designations are established by the Federal Government rule making process as part of CFR 14 section 71. You can see a list of the most recent set of Class D airspace designations in FAA Order 7400.9. See http://www.faa.gov/documentlibrary/media/order/jo_7400.9y.pdf

    You will have to do your own research.

    Even if you do the research and compile a list, your list will not be correct all the time.

    In my area, Waukegan (UGN) and Chicago Executive (PWK) are class D during the day, but revert to class E at night when the tower shuts down.

    South Bend (SBN) a class C airport reverts to class E when the tower shuts down.

    Why is it that you want or need to have this list?

    Thanks John, just what I needed.

    I wanted to add the numbers to my Private Ground School slides,

    In the US there are approximately:
    40 Class B airports
    116 Class C airports
    474 Class D airports
