Transitional Surface
G2GAB0110A 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
G2GAB0120A 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
G2GAB0130A 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
G2GAB0130A 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
G2GAB0140A 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)
G2GAB0150A 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.
