Class A.IFR flights only are permitted, all flights are subject to air traffic control service and are separated from each other.
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.
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 are as shown in the following table.

Note: No separation service is given outside controlled airspace. The information given under (b) will relate only to known IFR aircraft the presence of which might constitute a collision hazard to the aircraft informed. It will sometimes be based on data of doubtful accuracy and completeness, and the ATS cannot assume responsibility for its revision at all times, nor for its accuracy.2.3.1. Flight Information Service does not relieve the pilot-in-command of any of his responsibilities, and he has to make the final decision regarding any alteration of flight plan
The basic division of airspace is into regions of a convenient size known as “Flight Information Regions” (FIRs). They extend from ground level to a specified level or infinity. Throughout the FIR, Flight Information Service and Alerting Service are provided.
Pilots wishing to enter a control zone or a control area under IFR must request and obtain permission to do so from the controlling authority. Request by RTF should be made when at least 10 minutes flying time from the boundary.
Pilots in communication with the FIC before entering controlled airspace may request and obtain entry clearance via the FIC. After obtaining such clearance, they should remain in communication with the ACC until instructed to contact the controlling authority.
