Key Takeaways:

  • Entry into Class B airspace requires explicit ATC clearance (e.g., "cleared into Class B") and continuous two-way radio communication, with implicit clearances no longer considered sufficient.
  • Operating in Class B often mandates at least a private pilot certificate, prohibiting solo student, sport, and recreational pilot operations at primary airports, and requires a Mode C transponder and ADS-B Out (post-Jan 2020) within the 30 nm "Mode C veil."
  • Strict operational regulations apply, including a speed limit of 250 KIAS below 10,000 feet MSL (200 KIAS below Class B floors/in VFR corridors), and specific altitude requirements for large or turbine-powered aircraft within the pattern and on approach.
