Taiwan Strait ADIZ — Taipei FIR (RCAA)
Live status & airspace monitoring
The Taiwan Strait sits at the intersection of Taipei FIR (RCAA) and adjacent flight information regions managed by Shanghai (ZSHA), Fukuoka (RJJJ) and Hong Kong (VHHK). The Taiwan ADIZ and the adjacent ADIZ published by neighbouring authorities overlap as a matter of cartographic record; ADIZ is an identification construct and does not by itself restrict overflight. Published NOTAM zones for elevated activity are issued periodically and coordinated through ICAO ASIA/PAC channels. Trans-Pacific operators monitor these zones when planning east-west sectors.
Executive summary
The Taiwan Strait airspace — Taipei FIR (RCAA) bordered by Shanghai (ZSHA), Fukuoka (RJJJ) and Hong Kong (VHHK) — operates with regular scheduled traffic in 2026. The Taiwan ADIZ overlaps geographically with the adjacent ADIZ published by neighbouring authorities; ADIZ is an identification construct and does not by itself restrict overflight. Authorities publish periodic NOTAM zones flagged for elevated activity, coordinated through ICAO ASIA/PAC channels. Operators monitor these zones when planning trans-Pacific east-west sectors. The next review window should track CAA Taiwan and CAAC NOTAM publications and any ICAO ASIA/PAC coordination notices.

Regulatory context
ICAO ASIA/PAC coordinates regional flight information region boundaries and overflight protocols across RCAA, ZSHA, RJJJ and VHHK. CAA Taiwan publishes the Taipei FIR AIP and associated NOTAMs for RCAA. CAAC publishes NOTAMs for adjacent Shanghai region. ADIZ is an identification zone defined unilaterally by states and does not, by itself, close or restrict the underlying flight information region; ICAO Annex 11 governs the FIR construct. Periodic NOTAM zones flagging elevated activity are published by the relevant authorities and should be consulted via current AIS channels.
Industry implications
Taiwan Strait airspace remains operationally available for scheduled and overflight traffic in 2026. Trans-Pacific operators plan east-west sectors with reference to RJJJ Fukuoka corridors and southern routings through VHHK and Manila FIR as standard alternatives when NOTAM zones for elevated activity are in effect. Cost projections require verified industry data and are not currently displayed. Insurers and lessors monitor ICAO ASIA/PAC coordination notices and national AIS publications. The regulatory situation is structurally stable: ADIZ overlap is a long-standing published fact and operators have established workflows to handle periodic NOTAM zones.

Taiwan Strait ADIZ — Frequently Asked Questions
Common search queries answered with current status, FIR codes, and source citations.
- How does the Taiwan Strait ADIZ overlap affect overflight planning?
- Taipei FIR (RCAA) operates as the published ICAO flight information region for the Taiwan Strait. The Taiwan ADIZ and adjacent PRC-declared ADIZ overlap geographically; ADIZ is an identification zone and does not by itself close airspace. Operators coordinate with RCAA for traffic inside Taipei FIR and observe published NOTAM zones flagged for elevated activity. Trans-Pacific east-west traffic is typically routed via RJJJ (Fukuoka) corridors or southern routings through VHHK and Manila FIR depending on schedule and origin pair.
- Are flights to Taipei (RCTP) and Kaohsiung (RCKH) operating in 2026?
- Scheduled commercial service to Taipei Taoyuan (TPE, RCTP) and Kaohsiung (KHH, RCKH) continues with regular cadence in 2026. International carriers maintain published rotations; airport operations are routine. Operational decisions on individual sectors are made by each carrier in line with national civil aviation authority guidance from CAA Taiwan and home-state regulators.
- What sources track Taiwan Strait airspace and ADIZ activity?
- Public sources include ICAO ASIA/PAC regional coordination publications, CAA Taiwan AIP and NOTAMs published via RCAA, CAAC notices for ZSHA Shanghai FIR adjacencies, and Japan AIS NOTAMs covering RJJJ Fukuoka FIR boundaries. EUROCONTROL Network Manager and IATA also publish corridor-level guidance affecting trans-Pacific routings.
