Study Notes

Airspace Classifications and Requirements

  • Class A airspace spans from FL180 to FL600 and extends 12 nautical miles off the coast.
  • Class E airspace is found at surface, 700, 1200, or 14,500 feet AGL, beginning typically at 1200' AGL unless around airports where it may start lower.
  • Visibility and cloud clearance for VFR in Class E above 10,000' MSL requires 5 miles visibility, with cloud clearance of 1000' above, 1000' below, and 1 mile laterally.
  • Below 10,000' MSL, VFR minimums in Class E are 3 miles visibility and cloud clearance of 1000' above, 500' below, and 2000' laterally.
  • Cloud clearance and visibility for Class B airspace necessitate 3 miles visibility and being clear of clouds.

VFR Minimums and Special Procedures

  • Basic VFR minimums in Class E surface area include 3 miles visibility and a ceiling greater than 1000'.
  • Special VFR clearance in Class E surface airspace requires 1 mile visibility and being clear of clouds.
  • The minimum safe altitude in non-congested areas is 500' AGL while congested areas require 1000' above the highest obstacle within 2000' laterally.

Class D Airspace

  • Class D airspace typically has a 5-mile radius and extends up to 2500' AGL, depicted on sectional charts by a blue dashed circle.
  • Communication with ATC is mandatory before entering Class D airspace, where controllers provide sequencing and traffic information but not separation.
  • VFR minimums in Class D are 3 miles visibility and cloud clearances of 1000' above, 500' below, and 2000' laterally.

Class C Airspace

  • Class C airspace resembles double-stacked tuna cans with a lower cylinder having a 5-mile radius up to 1200' AGL and an upper cylinder extending out 10 miles to 4000' AGL.
  • Communication with ATC, usually approach control, is required before entering Class C airspace.
  • VFR weather minimums in Class C mirror those of Class D: 3 miles visibility and cloud clearances of 1000' above, 500' below, and 2000' laterally.

Class B Airspace

  • Class B airspace is shaped like an inverted wedding cake, extending from the surface up to 10,000' MSL within a radius of 15 to 30 nautical miles.
  • Operations in Class B require a private pilot license or endorsed student license, ATC clearance, and a suitable transponder.
  • VFR minimums in Class B entail 3 miles visibility while remaining clear of clouds.

Restricted and Prohibited Areas

  • Prohibited Areas are always off-limits, depicted by blue hatched lines accompanied by a “P”.
  • Restricted Areas indicate zones with invisible hazards (e.g., military activities) and require permission from controlling agencies to enter.
  • Warning Areas are defined by blue hatched lines, highlighting areas where U.S. restrictions do not apply, yet pose hazards.

Military Operations and Temporary Flight Restrictions

  • Military Operations Areas (MOAs) extend up to FL180; contacting the nearest Flight Service Station before entering is advised for traffic updates.
  • Temporary Flight Restrictions (TFRs) are established to protect surface activities, typically communicated through NOTAMs outlining affected areas and altitudes.

Additional Airspace Insights

  • TRSA (Terminal Radar Service Area) provides voluntary separation services between participating VFR and IFR traffic, indicated by black rings.
  • Class E airspace flexibility is shown by serrated blue lines, while Victor airways are 8 miles wide and extend from the base of Class E airspace to 18,000' MSL.
