1.1 As part of ongoing efforts to enhance the provision of aeronautical information services, the Civil Aviation Authority of Singapore (CAAS) is upgrading its current Aeronautical Information Management (AIM) publication system.This enhancement aims to improve the management and publication of Aeronautical Information Services (AIS) products, including the Aeronautical Information Publication (AIP), AIP Amendments, AIP Supplements and Aeronautical Information Circulars (AICs).
1.2 The publication of the AIP Singapore using the new AIM publication system will come into effect on 07 August 2025 coinciding with AIP Amendment cycle 04/2025.
1.3 AIP Singapore will continue to be accessible to users via the existing URL:
https://aim-sg.caas.gov.sg/aip, as there will be no changes to the current access link for retrieving the AIP.
1.4 The transition to the new AIM publication system involves the migration of existing AIP content, comprising aeronautical information and data, with an effective date of 12 June 2025. Accordingly, the effective date indicated in AIP Section GEN 0.4– Checklist of Pages for all published AIP pages will reflect as 12 June 2025, except for aeronautical charts which will retain their respective last amended dates.
1.5 All pages in the AIP updated for AIP Amendment cycle 04/2025 will indicate the effective date of 07 August 2025 with amendment markings placed adjacent to the respective amended text.
1.6 Following the implementation of the new AIM publication system, historical amendment effective dates will no longer be retained in the published AIP pages.
