Director of Air Navigation Services Technical Division

The Air Navigation Service Technical Division is a crucial division that provides support to the operation of Air Navigation Services. It comprises two sub-divisions, namely, the Air Traffic Management (ATM) and the Communication, Navigation, Surveillance & ATM Systems (CNS/ATM Systems).

In general, this division is responsible in:

  1. Drafting and developing air traffic services (ATS) procedures, including the development of contingency plans and route structures;
  2. Keep updated the airspace policies in accordance with the domestic and international standards and recommended practices including the development of coordination procedures between neighboring ATS providers and all relevant service providers;
  3. Develop, design, check, verify and maintain the instrument flight procedures for all domestic and international main airports within Peninsular, Sabah and Sarawak;
  4. Planning and development of Communication, Navigation, Surveillance and Air Traffic Management systems; and
  5. Continuous communication/engagement with stakeholders to ensure safe and sustainable aviation in Malaysia.

There are three (3) units under the ATM which are:

  1. Procedures for Air Navigation Services – Aircraft Operation (PANS-OPS);
  2. Procedures, Route Structures and Contingency Plan; and
  3. Airspace policies;

PANS-OPS is responsible for developing, designing, checking, verifying, and maintaining the instrument flight procedures for all domestic and international main airports within Peninsular, Sabah and Sarawak. This unit addresses and incorporates the use of navigation aids or other navigation technology that takes into account an aircraft’s performance capabilities, such as satellite-based navigation. These procedures, either conventional or performance-based navigation, are crucial for flights operating in various phases, including take-off, approach, and landing at aerodromes within Malaysia. PANS-OPS evaluate the terrain and obstacles during the design of IFP and then provides criteria for obstacle clearance during different phases of flight, ensuring that sufficient vertical and horizontal separation is maintained between the aircraft and obstacles, terrain, or other aircraft.

PANS-OPS unit produces the conventional and PBN IFP for all major aerodromes in Malaysia in the Malaysia Aeronautical Information Publication (AIP) through AIS.

Procedures, Route Structures and Contingency Plan Unit

The primary responsibility of this unit is to draft, develop and maintain the Manual of the Air Traffic Services, which is the procedure for CAAM’s Air Traffic Services (ATS) provider, which includes the development of regional contingency plans and route structures for safe and efficient air travel. The unit continuously ensures the consistency and interoperability of all related ATS procedures in compliance with international and national standards. The unit is responsible for providing air traffic services procedures for all phases of flight, including enroute, approach, and aerodrome control services.

Furthermore, this unit is responsible for designing and maintaining an efficient and effective ATS route structure (en-route) for the airspace under CAAM’s jurisdiction. The unit ensures that the route structure is safe, economical, and meets the needs of airspace users.

Additionally, the unit collaborates and coordinates with the Meteorology department to provide complete and effective air traffic management within Malaysia.

Airspace Policies Unit

This unit takes responsibility for ensuring compliance with national and international ATS standards and delicately adapts airspace specifications in Kuala Lumpur and Kota Kinabalu Flight Information Regions. This unit keeps the airspace policies up to date in accordance with domestic and international standards and recommended practices, including coordination procedures between domestic and international ATS providers and other relevant authorities regarding airspace management matters. Additionally, this unit also works closely with the military and other relevant agencies to ensure the flexible use of airspace to allow for the efficient and safe operation of both civil and military aircraft in the same airspace, while also ensuring that the requirements of both parties are met. The unit also ensures that the airspace specifications are comprehensive, effective, and tailored to address the needs of all stakeholders by taking into consideration various factors such as the specific requirements of the airspace users, geographical location, altitude, and aircraft performance. Thus, helps to optimise the use of airspace and improve Malaysian airspace capacity while maintaining safety standards.

As part of its responsibilities, this unit produces the Civil-Military Coordination Procedures (CMCP) document, Air Traffic Services Coordination Procedures (ATSCP) between Neighboring States and local ATS providers; and the Airspace Specification for KL & KK FIR published in the Malaysia AIP through AIS.

CNS/ATM Systems

The CNS/ATM Systems is responsible for providing the technological and system support for the ATM. The CNS/ATM Systems sub-division has three (3) units:

  1. a) Surveillance and ATM Systems Unit;
  2. b) Communication, Navigation and Meteorology System Unit; and
  3. c) Aviation System Block Upgrade (ASBU) Development and Monitoring and State Implementation Program unit

In general, the sub-division aims to strengthen CNS/ATM systems’ capabilities through system enhancements and the use of modern technology and efficient systems in tandem with the fast expansion of the global aviation industry. The CNS/ATM System sub-division will also implement initiatives on the CNS/ATM systems in KL and KK FIR to be in accordance with the ASBU and APAC seamless ANS Plan by coordinating with neighboring countries.

In addition, the unit is responsible for ensuring the development of the communication, navigation surveillance system and ATM system, by developing and providing technical specification reviews for all projects related to CNS/ATM systems and assisting in the procurement of CNS/ATM systems maintenance services contracts to ensure air traffic management operations.

The sub-division is also responsible for coordinating with other related local agencies, including neighbouring States, for joint implementation of the CNS/ATM system including meteorological systems to support the ATM operation and, at the same time, to ensure ICAO compliance. CNS/ATM system regularly monitors and prepares reports on performance-based implementation such as Performance-Based Communication and Surveillance (PBCS) to the ICAO and Central Reporting Agency (CRA). Additionally, whenever required, coordination with the Eurocontrol ATS Messaging Management Centre over the implementation of the ATS Message Handling System (AMHS) is also conducted on a regular basis.

The CNS/ATM system also coordinates, monitors and verifies flight inspection & calibration activities carried out on a periodic basis to ensure the accuracy and integrity of signals transmitted by the air navigation system in accordance with national and international standards and recommended practices.
