The name of the Charlie is also given (i.e.,). SFC is a typical floor altitude stating the Charlie in that sector begins at the surface (see figure 6). If Class C airspace underlies Class B, the ceiling is depicted with a “T” for top which lies just under the beginning of the Bravo. Similar to Class B, Charlie altitudes are given in MSL with the last two zeros omitted, but they can be differentiated by their magenta color (see figure 5).
Identify Class Charlie (C) airspace with a magenta circle on sectional charts (see figure 4). The name for the particular airspace will also be depicted ( for example). Some Class Bravo airspace locations have particular requirements that are described in a blue box with blue letters (see figure 3). Operations at or below that altitude (1200’ in this case) are not included in Class B. +12 indicates that the floor is at 1201’). Floor altitudes that are proceeded by a “+” indicate that the airspace starts upward from above this altitude (i.e. This means that 90/20 depicts that the airspace in that sector extends from 2000’ MSL up to and including 9000’. The airspace is often broken up into a variety of altitude sectors that are boxed off with blue lines. The MSL ceiling (top) and floor (bottom) altitudes of each sector are shown in blue figures and like most aviation altitudes, have the last two zeros omitted (see figure 2). Class BravoĬlass Bravo (B) is the next category and can be identified with large blue circles surrounding the area on sectional charts (see figure 1). Class A airspace is not depicted on sectional charts because it overlays all other categories. This extends from 18,000’ up to 60,000’ MSL (above mean sea level). Controlled Airspace Class AlphaĪlmost every class of airspace falls into the “controlled” category. The major difference is that IFR (Instrument Flight Rules) traffic is required to be in contact with ATC, have a filed flight plan, and have received ATC clearance at all times while in controlled airspace. There are two broad scopes of airspace: controlled and uncontrolled. These are each determined by the complexity or density of aircraft traffic, the nature of operations conducted, the degree of safety required, and what is in the best public and national interest. This structure incorporates different classifications of airspace. Now I feel I have learned one more thing on my way to my Pilots license and eventually IFR certified.Just like traffic on the ground, regulations govern air traffic to promote a safer, more efficient national airspace system. I don't actually "own" any charts yet, just use SkyVector and had never scrolled all the way to the top and recognized the margin data. In the margin of the chart, there will be a table listing all of the restricted areas
I am planning on building my 40 hr and 125 hr requirement by flying a lot between RYY- HXD, as in the summer I spend a lot of my weekends down at Hilton Head. I had been "flying" IFR routes usually bypassing these areas and then it hit me the other day that I might not need to bypass them, as I can just get permission. I have literally spent 1000s of hours on MS flight simulator, and reading these forums, etc. But I plan on starting my license after years of "teaching myself" as much as I can. Then you probably shouldn't be planning a flight then Winkīoth I guess. Just got that by googling BULLDOG MOA, and presto. Information concerning ATCAA airspace can be obtained from the associated Air Route Traffic Control Center. For the latest SUA information, call your local Flight Service Station at 1-800-WX-BRIEF. Pilots should use this information for planning purposes only. and as has previously been mentioned.ĭepicted Special Use Airspace ( SUA) and Air Traffic Control Assigned Airspace (ATCAA) data may not be complete. Some of them look rather formidable, but then you find out by reading the chart that, for example, many of the Luke AFB MOAs around the Phoenix area don't start until 14,000' AGL and above, so you could safely cruise under the MOA in a Cessna all day long Another thing: pay attention to the altitude on restricted areas and MOAs.
