ENR 1.4 ATS airspace classification and description

1. CLASSIFICATION OF AIRSPACE

ATS airspace is qualified and designated in accordance with the following:

1.1 CLASS A

IFR flights are only permitted, all flights are subject to air traffic control service and are separated from each other.

1.2 CLASS B

IFR and VFR flights are permitted, all flights are subject to air traffic control service and are separated from each other.

1.3 CLASS C

IFR and VFR flights are permitted, all flights are subject to air traffic control service and IFR flights are separated from other IFR flights and from VFR flights. VFR flights are separated from IFR flights and receive traffic information in respect of other VFR flights.

1.4 CLASS D

IFR and VFR flights are permitted and all flights are subject to air traffic control service, IFR flights are separated from other IFR flights and receive traffic information in respect of VFR flights, VFR flights receive traffic information in respect of all other flights.

1.5 CLASS E

IFR and VFR flights are permitted, IFR flights are subject to air traffic control service and are separated from other IFR flights. All receive traffic information as far as a practice.

1.6 CLASS F

IFR and VFR flights are permitted, all participating IFR flights receive an air traffic advisory and all flights receive flight information on request.

1.7 CLASS G

VFR flights are only permitted and receive flight information service if requested.

2. INTRODUCTION

Within the Sarajevo FIR the airspace is divided into four (4) Classes C, D, E and G. Airspace classes C, D and E are broadly with those recommended by ICAO.

Class G of airspace is different than ICAO classification. Difference is published in GEN 1.7

ICAO Classes A, B and F are at the present not used.

The airspace classes are described below with respect to the conditions of use and the services provided with.

Abbreviations used in this context have the following meaning:

ATC - Air Traffic Control Service;
FIS - Flight Information Service;
ALRS - Alerting Service;
RTF - Continuous Two Way Radio Communication.

The vertical and lateral limits of the airspace are contained in chapter ENR 2.1.

3. CLASS C - CONTROLLED AIRSPACE

The provisions of Class C are shown below:

IFR		VFR
IFR from IFR, IFR from VFR	Separation	VFR from IFR
Air Traffic Control Service	Service provided	a) ATCS for separation from IFR, b) VFR/VFR traffic information (and traffic avoidance advice on request)
Not applicable	VMC visibility and distance from cloud minima	At and above FL 100: - 8 KM visibility - 1.500 M horizontal and 300 M vertical distance from cloud Below FL 100: - 5 KM visibility - 1.500 M horizontal and 300 M vertical distance from cloud
Not applicable	Speed limitation	250 KT IAS below 3050 M (10000 FT AMSL)
Continuous two-way	RTF	Continuous two-way
YES	ATC Clearance	YES

* The height of transition altitude is 10000 FT AMSL, so FL 100 is used in line of 10000 FT.

4. CLASS D – CONTROLLED AIRSPACE

The provisions of Class D are shown below:

IFR		VFR
IFR from IFR	Separation	NIL
Air Traffic Control Service, Traffic information about VFR flights (and traffic avoidance advise on request)	Service provided	IFR/VFR and VFR/VFR Traffic information (and traffic avoidance advise on request)
Not applicable	VMC visibility and distance from cloud minima	At and above FL100: - 8 KM visibility - 1.500 M horizontal and 300 M vertical distance from cloud Below FL100: - 5 KM visibility - 1.500 M horizontal and 300 M vertical distance from cloud
250 KT IAS below 3050 M (10000 FT AMSL)	Speed limitation	250 KT IAS below 3050 M (10000 FT AMSL)
Continuous two-way	RTF	Continuous two-way
YES	ATC Clearance	YES

* The height of transition altitude is 10000 FT AMSL, so FL 100 is used in line of 10000 FT.

5. CLASS E – CONTROLLED AIRSPACE

The provisions of Class E are shown below:

IFR		VFR
IFR from IFR	Separation	NIL
Air Traffic Control Service and as far as practical, Traffic information about VFR flights	Service provided	Traffic information as far as practical
Not applicable	VMC visibility and distance from cloud minima	- 8 KM visibility - 1.500 M horizontal and 300 M vertical distance from cloud
250 KT IAS below 3050 M (10000 FT AMSL)	Speed limitation	250 KT IAS below 3050 M (10000 FT AMSL)
Continuous two-way	RTF	NO
YES	ATC Clearance	NO

* The height of transition altitude is 10000 FT AMSL, so FL 100 is used in line of 10000 FT.

6. CLASS G – AIRSPACE

The provisions of Class G are shown below:

IFR		VFR
NIL	Separation	NIL
NIL	Service provided	FIS
NIL	VMC visibility and distance from cloud minima	- 1.5 KM visibility - clear of cloud and in sight of ground or water Remark: 800 M for Rotorcraft, Air Ships and Free Balloons. Additionally: Adequate opportunity to observe obstacles on time shall exist.
NIL	Speed limitation	250 KT IAS below 3050 M (10000 FT AMSL)
NIL	RTF	NO
NO	ATC Clearance	NO

* The height of transition altitude is 10000 FT AMSL, so FL 100 is used in line of 10000 FT.
