    Why airspace is classified?

    The goal is to provide maximum flexibility for pilots while ensuring safe operations based on the level of risk associated with traffic density and the type of flight.

    How does airspace classification relate to traffic density?

    Higher traffic density and faster flight speeds typically require more strict separation rules. Light traffic and slower speeds allow pilots to manage their separation.

    How does airspace classification ensure safety?

    The system ensures separation in areas of dense and high-speed operations and allows more freedom in less busy areas.

    Study Notes

    Airspace Classification

    • The FAA categorizes airspace above the US into classes with specific operating rules.
    • The system aims to provide pilot flexibility while managing risk based on traffic density.
    • Different airspace classes allow varying levels of control and separation.
    • Dense or high-speed operations require more separation and active control by ATC.
    • Lighter traffic areas allow pilots to manage traffic separation when weather permits.

    General Airspace Categories

    • Positive Controlled Airspace (PCA): ATC separates all aircraft (IFR and VFR).
    • Controlled Airspace: ATC separates IFR aircraft, but VFR pilots control separation.
    • Uncontrolled Airspace: Pilots provide their own separation.
    • Special Use Airspace: Airspace with special operating restrictions & rules.

    Positive Controlled Airspace

    • PCA restricts or prohibits VFR flights.
    • It includes high-altitude flights or airspace around high-density airports.

    Controlled Airspace

    • ATC provides separation services for IFR aircraft.
    • IFR aircraft are permitted in cloud conditions or reduced visibility.
    • VFR aircraft in controlled airspace are responsible for their own separation from other aircraft.
    • VFR flights are permitted when weather conditions allow pilots to visually separate from other aircraft.

    Uncontrolled Airspace

    • ATC does not provide separation services in uncontrolled airspace.
    • All separation is managed by pilots.
    • Applies primarily to airspace below 1,200 feet above ground level (AGL) distant from busy airports.

    Special Use Airspace

    • Designated by the FAA for specific activities requiring area restrictions.
    • Some types are regulatory (part of FAR Part 73); others are non-regulatory (described in FAA Order 7400.8).

    Controlled vs. Uncontrolled Airspace

    • Separation services are only available to pilots in controlled airspace.

    Airspace Review and Classification

    • In 1992, the FAA re-evaluated and simplified airspace classifications.
    • These are now categorized as Class A, B, C, D, E, and G. Class F is an ICAO classification without an equivalent in the US.
    • In general, Classes A, B, C, D, and E are considered controlled airspace and Class G is uncontrolled.
