International conventions and ICAO standards applicable in PNG (Chicago Convention, Annexes)
Chicago Convention and ICAO standards
PNG is a contracting state of the Chicago Convention. The Convention recognises each state’s complete sovereignty over its airspace (Article 1) and requires states to apply ICAO Standards and Recommended Practices to the extent practicable. ICAO Annexes cover licensing, rules of the air, operations, airworthiness, aerodromes, security, dangerous goods and environment. Annexes are not self-executing in PNG; they take effect through the Civil Aviation Act and PNG CARs.
Permissions and differences
Scheduled international air services require permission, and non-scheduled flights may also need authorisation. Foreign operators must comply with PNG law and any conditions attached to their permit. PNG files differences from ICAO standards where its rules differ. A foreign licence or certificate is not automatically valid for PNG operations; validation, acceptance or conversion may be required.
Worked example
A foreign operator plans a one-off charter carrying passengers into Port Moresby. The crew holds foreign licences and the aircraft has a foreign certificate of airworthiness. The operator assumes the Chicago Convention gives automatic cabotage or charter rights. It does not: the flight needs PNG permission, and the crew and aircraft must satisfy PNG acceptance requirements.
Traps
Do not treat an ICAO Annex as directly enforceable law in PNG. Do not confuse a foreign licence with PNG authorisation. Do not assume “non-scheduled” means “no permission required”.
