This category contains geospatial information related to air transportation such as air space, aerodrome and airport.

  • Transitional Surface

    G2G
    AB0110

    A surface around a runway strip sloping up outwards to the inner horizontal surface that defines the volume of upwards air space that should be kept free from obstacles to protect aircraft in their final phase of approach.

  • Transitional Surface

    G2G
    AB0110

    A surface around a runway strip sloping up outwards to the inner horizontal surface that defines the volume of upwards air space that should be kept free from obstacles to protect aircraft in their final phase of approach.

  • Inner Horizontal Surface

    G2G
    AB0120

    A horizontal surface around a runway strip above an aerodrome and its vicinity that defines the volume of upwards air space that should be kept free from obstacles to protect aircraft for visual circling prior to landing.

  • Conical Surface

    G2G
    AB0130

    A surface sloping up outwards from the periphery of the inner horizontal surface that defines the volume of upwards air space that should be kept free from obstacles to protect aircraft for visual circling prior to landing.

  • Conical Surface

    G2G
    AB0130

    A surface sloping up outwards from the periphery of the inner horizontal surface that defines the volume of upwards air space that should be kept free from obstacles to protect aircraft for visual circling prior to landing.

  • Outer Horizontal Surface

    G2G
    AB0140

    A specified portion of a horizontal plane beyond the limit of the conical surface that defines the volume of upwards air space that should be kept free from obstacles to facilitate instrument approach procedures.

  • Outer Horizontal Surface

    G2G
    AB0140

    A specified portion of a horizontal plane beyond the limit of the conical surface that defines the volume of upwards air space that should be kept free from obstacles to facilitate instrument approach procedures.

  • Obstacle Free Zone (OFZ)

    G2G
    AB0150

    A volume of air space in the immediate vicinity of a precision approach runways defined by the inner approach, inner transitional and balked landing surfaces, which must be kept free from fixed objects.

  • Threshold

    G2G
    AB0160

    The beginning of that portion of the runway usable for landing.
