CAAS provides the necessary aeronautical information to facilitate the safety, regularity and efficiency of international and national air navigation for the entire Singapore and for airspace over the high seas encompassed by the Singapore Flight Information Region (FIR).

The information is published in the following four forms:


NOTAM List

NOTAMs (Notice to Airmen) contain information useful for aircraft pilots on potential flight hazards.

All valid NOTAMS are compiled in a monthly NOTAM List. It also has a checklist of current AIP Supplements (SUPs) and the reference numbers of the latest Singapore AIP amendment, SUP and Aeronautical Information Circular (AIC) issued.

Aeronautical Information Circular (AIC)

AIC contains explanatory and advisory information on technical/ legislative/administrative matters; and the long-term forecast of major changes in legislation, regulations, procedures or facilities affecting flight safety.

Aeronautical Information Publication (AIP) Singapore

AIP Singapore contains basic permanent aeronautical information essential to air navigation within the Singapore FIR. It is made up of three parts, namely General (GEN), En-route (ENR) and Aerodromes (AD).

AIP Singapore is updated regularly, with AIP amendments issued once every two months.

AIP Supplement (SUP)

SUP contains information on temporary changes on air navigation in the Singapore FIR. It supplements the permanent aeronautical information in AIP Singapore.
