The services are provided in accordance with the provision contained in the following ICAO documents:

Differences from these provisions are detailed in sub - section GEN 1.7.

3.3.2  AREA OF RESPONSIBILITY

Air Traffic Services are provided for the entire territories, including territorial waters, and in the airspace over the high seas encompassed by the BAHRAIN FIR / BAHRAIN UIR.

3.3.3  TYPE OF SERVICES

The following types of services are provided:

With the exception of services provided at military air bases, the following types of services are provided at aerodromes:

For military ATS within the Kingdom of Bahrain see OBBS AD 2.17 and OBKH AD 2.17.

3.3.3.1 Air Traffic Services are provided in accordance with the standards specified in Annex 11 to the Convention on International Civil Aviation. Airspace is classified in accordance with Appendix 4 to Annex 11, and a description of the system with an indication of the utilization in the BAHRAIN FIR / BAHRAIN UIR is set out in ENR 1.4.

Air Traffic Control is exercised:

  1. In Class A Airspace which in the BAHRAIN UIR encompasses all Controlled Airspace at and above FL 150 and;

  2. In Class C Airspace which in the BAHRAIN FIR encompasses all Controlled Airspace below FL 150.

Note: Controlled Airspace is a generic term which covers ATS Airspace Classes A, B, C, D & E as defined in Appendix 4 to Annex 11.

3.3.3.2 Flight Information Service and Alerting Service within the Area of Responsibility outside the Control Zones, and Air Traffic Control service in airways within the Area of Responsibility are provided by one Centre (ACC Bahrain). Within Control Zones the Services are provided by the Approach Control Unit concerned.

The Taxis of each airway is constituted by a line connecting significant points identified as a rule by radio navigational facilities.

3.3.3.3 Air Traffic Control, Flight Information and Alerting Services are provided by:

  1. ACC Bahrain in the Bahrain CTA and along the airways, including those parts of the airways traversing Control Zones.

  2. The relevant Approach Control Unit and Aerodrome Control Unit, in co - ordination with Bahrain as necessary, for arriving and departing aircraft.

3.3.3.4 The description of the airspace designated for Air Traffic Services purposes is contained in several tables, all forming part of ENR 3.
3.3.3.5 In general, the air traffic rules and procedures in force and the organization of Air Traffic Services are in conformity with ICAO Standards, Recommended Practices and Procedures. Differences between the National and International Rules and Procedures are given in GEN 1.7 . The Regional Supplementary Procedures are given in full with an indication where there is a difference.
3.3.3.6 Prohibited, Restricted and Danger areas are established within BAHRAIN FIR / BAHRAIN UIR. These areas are shown in ENR 5. Activation of areas subject to Intermittent activity is notified in advance by NOTAM, given reference to the area only by its designation.

3.3.4  COORDINATION BETWEEN THE OPERATORS AND ATS

Coordination between the operator and Air Traffic Services is affected in accordance with Annex 11 and Doc 4444 (PANS - ATM).

Coordination for Special Use of Airspace

In order to ensure that activities potentially hazardous to civil aircraft are coordinated between Military users and ATC units and to:

  1. Allow timely promulgation of information;

  2. Minimize interference with normal civil aircraft operations;

  3. Avoid hazards to civil aircraft;

The unit requesting special use of airspace shall submit a request to Bahrain ATC Head of ATC Operations for approval at least 10 days prior to the proposed operation. All requests shall include date and times of the request as well as the specific area requested, defined by Latitude and Longitude coordinates and altitude limits in terms of MSL.

3.3.5  MINIMUM FLIGHT ALTITUDES

The minimum flight altitudes on the ATS routes as listed in ENR 3 have been determined to ensure at least 300 M (1000 FT) vertical clearance above the highest obstacle within 5 NM from the edge of airways.

However, where the angular divergence of the navigational air signal in combination with the distance between the navigational aids could result in an aircraft being more than 5 NM (9 KM) on either side of the centre line, the 5 NM (9 KM) protection limit on each side of the centre line of the ATS route is increased by the extent to which the divergence is more than 5 NM (9 KM) from the centre line.

Note: The navigation performance accuracy necessary for operation on air routes within BAHRAIN UIR is expressed as RNAV type. RNAV type is containment value expressed as a distance in NM from the intended position within which flights would be for at least 95 per cent of the total flying time. For operation on the air routes in the BAHRAIN UIR, the required radio navigation specification (RNAV) is RNAV 5. RNAV 5 represents a navigation accuracy of plus or minus 9.26 KM (5 NM) on a per cent containment basis. RNAV 5 application in BAHRAIN UIR is detailed in ENR 1.3.4.
