Below is just to help myself to better gain knowledge about read sectional charts . This is what I've used to refresh myself on sectional charts and has been a learning experience about reading a chart more in depth. There may be errors; if they are pointed out I will fix them .  \nThis is an overview of the main area I look at when going off my sectional chart. It has a bunch of congested areas and different airspaces .  \nAIRSPACE  \nThis is the markings of a Class B airspace, specifically Boston Airport. The blue lines show the different levels and the blue text (pictured more closely) definite the limits of each\"shelf. \" The Bravo airspace is normally described as an upside down wedding cake (more than two layers)  \nThis is the circle around any Class B airspace that is 3o nautical miles . It is called the Mode C Veil, which requires any aircraft flying within 30nm of a Class B to have a Mode C altitude encoding transponder . ATC must be able to tell the altitude of your aircraft even if they are not talking to you due to the volume of traffic in the area . If you are required to have the right equipment to enter this space, yet you are not within the Bravo airspace yet and do not need to be cleared into the Mode C Veil area .  \nVFR Sectional Chart Cessna Chick  \nVFR Sectional Chart Cessna Chick  \nClass C  \nThis is the markings of a Class C airspace . The magenta lines define the inner and outer \"shelf. \" Pictured more closely is the magenta text that define the limits of each area . This one defines the inner core from the surface to 4100ft.  \nClass D  \nThis is a Class D airport, it is the blue dashed lines . It also has a VOR at the airport which is the bigger blue solid line with radial marks for the VOR. The Class D is not necessarily a perfect circle, as you can see with this one . Above is the limit of the Class D airspace since there is only one area until like Class B/C airspaces so surface to the number in the box is assumed. Class D is typically Surface to 2,500ft MSL as it is at Bridgeport but I’ve included examples where it is higher due to terrain, they are all equivalent to 2,500ft AGL.  \nVFR Sectional Chart Cessna Chick  \nVFR Sectional Chart Cessna Chick  \nClass E  \nThis airspace is a Class E-surface to 700ft AGL. Unlike other airspaces, this class is always those vertical limits. Do not get confused by the VOR near this airport, it is blue but the dashed magenta circle is the limits of the airspace . I know when I look quickly you may see the blue and assume it is Class D airspace, so always check the colors and the line is dashed not hashed.  \nThis is Class E airspace too, but now it starts at 700ft to 1200ft. Class E is the hardest airspace to read on the sectional, since it has many denotations . This is mainly to help IFR flights with ATC contact since they wouldn’t get that in Class G airspace. Roundup airport is in Class G airspace under the Class E. It is surround by Class E airspace starting at 700ft to help IFR traffic approach the airport for landing.  \nThis is also Class E airspace, but it starts at 1,200ft. In the Northeast, you won’t see this on sectional charts because it is assumed. It is a very congested area with lots of air traffic all airspace is at least Class E starting at 1,200ft. This symbol is more common out west where these are less dense areas .  \nThis is the last Class E marking you’ll find on a sectional. This blue zipper line is when Class E is denoted, but it doesn’t have a standard altitude. You can see on either side of this 1700MSL and 5500 MSLit’s where the Class E starts on either side of the zipper line .  \nVFR Sectional Chart Cessna Chick  \nVFR Sectional Chart Cessna Chick  \nTRSA  \nAbove is a TRSA airspace-Terminal Radar Service Area . It's an optional class C airspace-in away.
