Aeronautical Information Service


The Civil Aviation Authority Suriname (CASAS) has adopted ICAO Annex15 “Aeronautical Information Service” to the Chicago Convention as the Civil Aviation Regulation Suriname (CARS) 20.


The object of the Aeronautical information service is to ensure the flow of information necessary for the safety, regularity and efficiency of international air navigation. CARS 20 Aeronautical Information Service governs how aeronautical information/data is gathered and managed and defines how aeronautical information service receives and/or originates, collate or assemble, edit, format, publish and distribute specified aeronautical information/data. The goal is to satisfy the need for uniformity and consistency in the aeronautical information/data that is required for the operational use in international air navigation.

To support that requirement, the Aeronautical Information Service provides a range of information/data to airlines, pilots and all those involved in flight planning and international air navigation in the Paramaribo Flight Information Region.

Responsibilities and functions

AIS shall ensure that aeronautical information/data relating to the entire territory of the Republic of Suriname, is adequate and of required quality and timely. All services associated with aircraft operations shall timely provide the required aeronautical information/data to aeronautical information service.

Aeronautical information/data should be published as an Integrated Aeronautical Information Package (IAIP), composed of the following element;

- The Aeronautical Information Publication (AIP), including amendment services;

- Supplements to the AIP;

- NOTAM (Notice to Airmen) and Pre-flight Information Bulletins (PIB);

- Aeronautical Information Circulars (AIC);

- Checklist and lists of valid NOTAM.

The IAIP details data regarding the organization, operation and location of Aerodromes, Airspace, Navigation Aids and facilities as well as any information relevant to the safety of flight within the airspace.

AIS does not originate the information, but collates it on behalf of the sponsor (i.e. the authority responsible for the facility or service) and publishes it in accordance with internationally agreed formats.


The transition from Aeronautical Information Service (AIS) to Aeronautical Information Management (AIM)

The new age of the Internet, satellite navigation and computer networks, yet our approach to aeronautical information distribution is still based on paper charts, paper documentation and telex-based text messages.

The computer-based navigation systems, and area navigation (RNAV), required navigation performance (RNP) and air traffic management requirements, introduced a need for new corresponding AIS requirements for quality and timeliness of aeronautical information.

The present AIS need to transform to an information management service, changing duties, responsibilities and scope to satisfy these new requirements and to cope with and manage the provision of information. The definition of a future high-level view as to the shape, nature and content of a strategy for the evolution from traditional product-centric AIS to the enlarged scope of data-centric Aeronautical Information Management (AIM) began.

The transition to AIM will not involve many changes in terms of the scope of information to be distributed. The major change will be the increased emphasis on data distribution, which should place the future AIM in a position to better serve airspace users and Air Traffic Management in terms of their information management requirements.

This process is in progress and 45% is already implemented.
