Study Notes

Airspace Classifications and Requirements

  • Class C Airspace: Requires 500' below, 1000' above, and 2000' horizontal clearance; visibility of 3 statute miles (SM).
  • Class D Airspace: Same weather requirements as Class C; 500' below, 1000' above, 2000' horizontal and 3 SM visibility.
  • Class A Airspace: Encompasses airspace from 18,000' MSL to FL 600; requires IFR operations, ATC clearance, and specific equipment including a Mode C Transponder.
  • Class B Airspace: Extends from the surface to 10,000' MSL around busy airports; tailored configuration; requires ATC clearance and separation services for all aircraft.
  • Class E Airspace: Controlled airspace not classified as A, B, C, or D; can start from the surface or higher altitudes; varies depending on location.

Airspace Dimensions and Regulations

  • Class C Dimensions: Consists of two concentric circles; inner circle 5 NM radius from the surface to 4,000' AGL, and outer circle extends from 1,200' AGL to 4,000' AGL, typically with a 20 NM radius.
  • Class D Dimensions: Generally extends from the surface to 2,500' AGL with individual configurations; radio contact with ATC required before entering.
  • Class E Levels: Exists at various heights: Surface, 700' AGL, 1,200' AGL, 14,500' MSL, and above FL 600.

Weather Minimums

  • Uncontrolled Airspace (<1,200' AGL):
    • Day: 1/2 mile visibility, clear of clouds.
    • Night: 1 mile visibility, clear of clouds.
  • Special Use Airspaces: Include prohibited areas (National Security), restricted areas (hazards like missiles), warning areas (extends 3 NM from the coast), and alert areas with high traffic volumes.

VFR Sectional Details

  • Magenta circles indicate VFR reporting points; blue and magenta airports indicate with or without control towers, respectively.
  • Class B Airspace depicted with solid blue circles on VFR sectionals; controlled airspace indicated via dashed blue for Class D.
  • Maximum Elevation Figure (MEF) numbers indicate the highest feature in specific areas, rounded to the next hundred feet.

Communications and Required Equipment

  • ATC clearance is mandatory in Class B airspace; VFR operations require two-way communication equipment and a working transponder.
  • EFAS (Enroute Flight Advisory Service) provides weather advisories for enroute aircraft; contact on frequency 122.0.

Additional Airspace Types and Restrictions

  • Victor Airways: Depicted by blue lines between VORs, extending from 1,200' to 18,000' MSL, are Class E airspace.
  • Helicopter Operations: Traffic patterns for Army helicopters at 700' AGL, respecting visibility minimums.
  • Restricted Areas: Pilots are advised to maintain a distance of 3 NM unless permission is obtained; thunderstorms to be avoided by a 20 NM radius.

Important Airspace Symbols

  • Magenta Circle with "R" on VFR sectional: Indicates a private airstrip or airport.
  • Tick Marks around Airport Symbols: Indicate fuel availability and operational hours.
  • Star Icon: Means a rotating beacon is operational from sunset to sunrise.
