ENR 1.4 ATS AIRSPACE CLASSIFICATION

In Malaysia, airspace is divided into various classes (A, B, C, and G) based on flight operations and traffic management. Class A is strictly for IFR flights and involves full air traffic control, while Class B allows both IFR and VFR with air traffic services. Class C also accommodates both types of flights, providing certain separation and traffic information. Class G is less regulated, permitting both IFR and VFR without air traffic control, relying instead on flight information services.

Key points

• Airspace is classified into Classes A, B, C, and G based on the level of control and type of flight allowed.
• Class A is exclusive to IFR flights and requires constant air traffic control.
• Classes B and C support both IFR and VFR flights with varying degrees of separation and traffic information.
• Class G allows both types of flights with minimal regulation, based on visibility conditions and requests for information.
