Key Takeaways:

  • Explicit ATC clearance, typically hearing the word "cleared," is required before entering Class B airspace; implied clearances are not sufficient.
  • Operations in Class B airspace mandate a two-way radio, and aircraft within the 30 nm Mode C veil must have a Mode C transponder and (post-2020) ADS-B Out equipment.
  • Speed is restricted to 250 knots indicated airspeed (kias) below 10,000 feet MSL, and 200 kias below the Class B floor or in a VFR corridor, which ATC cannot waive.
  • Pilot qualifications for Class B vary, with many primary airports requiring at least a private pilot certificate, and solo student, sport, or recreational pilot operations generally prohibited.
