1.4.2  ATS airspace description

1.4.2.1 Within the BAHRAIN FIR / BAHRAIN UIR the Airspace is further divided into four classifications. A, B, C and G. Three ICAO Classifications, D, E and F which have been adopted by the Kingdom of Bahrain are available for use but at present no portions of BAHRAIN FIR / BAHRAIN UIR Airspace have been classified.

Airspace classified as A, B and C is Controlled Airspace.

The Airspace Classifications are described in subsequent paragraphs, and notifications, descriptions and procedures of individual Airspaces within each classification are contained in ENR 2, ENR 3 and AD 2.
