Airspace classes and structure

Read the official rule

The guidance clarifies that during times when air traffic control isn't available at regional airports, the classification of certain airspaces changes from Class C to Class G. Pilots must adhere to Visual Flight Rules and familiarize themselves with airspace regulations and requirements for each class, including communication and separation protocols.

Key points

  • Control zones switch from Class C to Class G without ATC service.
  • Pilots must follow Visual Flight Rules at all times.
  • Different classes of airspace have specific requirements for pilots.
  • Separation and services differ between IFR and VFR pilots.
