ENR 1.4 ATS AIRSPACE CLASSIFICATION AND DESCRIPTION

1.4.1 ATS airspace classification

ATS airspaces are classified and designated in accordance with the following:

Class A. IFR flights only are permitted, all flights are provided with air traffic control service and are separated from each other.

Class B. IFR and VFR flights are permitted, all flights are provided with air traffic control service and are separated from each other.

Class C. IFR and VFR flights are permitted, all flights are provided with 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.

Class D. IFR and VFR flights are permitted and all flights are provided with 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.

Class E. IFR and VFR flights are permitted, IFR flights are provided with air traffic control service and are separated from other IFR flights. All flights receive traffic information as far as is practical.

Class F. IFR and VFR flights are permitted, all participating IFR flights receive an air traffic advisory service and all flights receive flight information service if requested.

Class G. IFR and VFR flights are permitted and receive flight information service if requested.

The requirements for the flights within each class of airspace in JEDDAH FIR are as shown in the following table:

Unless otherwise authorized or required by an ATC unit, aircraft operated below ALT 10,000 FT, anywhere in JEDDAH FIR, shall not exceed the following values of indicated airspeed (IAS), except that the minimum safe operating speed for a particular aircraft shall always be the determining factor when it is greater than the maximum speeds prescribed below.
  1. Within an aerodrome traffic circuit (at or below 2500FT SFC within 4NM of primary aerodrome):
    1. turbine engine aircraft - 200 KT; or
    2. reciprocating engine aircraft - 156 KT;
  2. Elsewhere than in 1. above: 250 KT
