Singapore Aeronautical Search and Rescue

The Civil Aviation Authority of Singapore (CAAS) coordinates aeronautical search-and-rescue (SAR) operations within Singapore’s Search and Rescue Region (SRR) through the Singapore Rescue Coordination Centre (RCC). The RCC is operated by CAAS and located at the Singapore Air Traffic Control Centre; CAAS works with MINDEF, the Maritime and Port Authority of Singapore, Meteorological Service Singapore, the Ministry of Health, SPF, SCDF, Changi Airport Group and other relevant bodies (CAAS, updated 3 September 2026).

Coordination, standards and readiness

CAAS says its SAR services follow ICAO Annexes 12 and 13, regional supplementary procedures, the International Aeronautical and Maritime Search and Rescue Manual, and Singapore’s local SAR procedures. The RCC coordinates operations while police, SCDF and MPA remain on standby; CAAS also conducts annual exercises to strengthen operational readiness and crisis-management capability (CAAS, updated 3 September 2026).

The RCC is supported by aeronautical, maritime and public telecommunication services from listed search-and-rescue units. CAAS’s table identifies support from Singapore/MINDEF, the Police Coast Guard, Changi Airport Emergency Services, the Singapore Civil Defence Force and Pacific Flight Services, with additional coordination with the US Air Force Pacific Region RCC. The listed resources include fixed-wing and rotary-wing aircraft, rescue vessels and response facilities; the table describes capability and coordination arrangements, not a promise that every listed asset is dispatched to every incident (CAAS, updated 3 September 2026).

Detection and communications

Singapore’s Mission Control Centre provides COSPAS–SARSAT services in Singapore and adjacent Flight Information Regions for distress beacons operating on 406 MHz, helping detect and track aircraft in distress. The distress frequency 121.5 MHz is monitored continuously by Changi Control Tower, Seletar Control Tower and the Singapore Air Traffic Control Centre. Singapore-registered aircraft operators must register qualifying 406 MHz Emergency Locator Transmitters with the RCC and obtain approval at least two days before testing them (CAAS, updated 3 September 2026).

CAAS says all search aircraft are land planes carrying survival equipment such as inflatable rubber dinghies with general-purpose first-aid supplies, emergency rations and survival radio equipment. Permanent SAR aircraft use defined callsigns: fixed-wing aircraft use “Rescue” followed by a number from 61 to 85, while rotary-wing aircraft use “Rescue” followed by a number from 10 to 19. These details help identify the service’s detection, communications and response layers, but they do not establish a public estimate of response time or a guaranteed search outcome (CAAS, updated 3 September 2026).

Mutual assistance and operational boundary

Singapore has SAR agreements with Indonesia, Malaysia, the Philippines, Thailand and Vietnam, providing for mutual assistance within each country’s SRR. CAAS also records an agreement with the US Air Force Pacific RCC and a letter of understanding with Brunei that allows Singapore’s RCC to draw on Brunei resources when necessary. These arrangements support coordination and assistance; they do not transfer sovereignty over another country’s airspace or guarantee that a particular foreign resource will be available in every incident (CAAS, updated 3 September 2026).

The page also sets out an operator-facing Emergency Locator Transmitter (ELT) boundary. ELTs may activate automatically or manually, and operators of Singapore-registered aircraft must ensure that onboard ELTs capable of transmitting on 406 MHz are registered with CAAS. Operators must notify the RCC when registration information changes, including after a new registration, aircraft deregistration, ELT replacement, battery-expiry change or aircraft colour or livery change. For a test, the operator must request RCC approval at least two days in advance and provide aircraft, timing, location, beacon-ID and frequency details (CAAS, updated 3 September 2026).
