Key Takeaways:

  • Class B airspace surrounds the busiest airports, is uniquely tailored (often described as "upside-down wedding cakes"), and strictly requires explicit ATC clearance and continuous two-way radio communication for entry.
  • Operations within Class B typically demand at least a private pilot certificate (prohibiting solo student, sport, and recreational pilots) and specific equipment, including a Mode C transponder and ADS-B Out within a 30 nm radius.
  • Key operational rules include VFR minimums of 1,000 ft ceiling, 3 sm visibility, and clear of clouds, alongside a firm speed limit of 250 KIAS below 10,000 ft MSL (or 200 KIAS below the Class B floor or in a VFR corridor), which ATC cannot override.
