Aviation Security and Unlawful Interference
Annex 17 and the security framework
Annex 17 sets Standards and Recommended Practices for security - safeguarding civil aviation against acts of unlawful interference. It requires each State to establish a national civil aviation security programme, designate an appropriate authority, and ensure security controls at airports and on aircraft. It works alongside the Tokyo Convention 1963 (offences on board), the Hague Convention 1970 (unlawful seizure of aircraft), and the Montreal Convention 1971 (acts of violence at airports and against aircraft), plus the Montreal Protocol 1988 on airport violence.
Key concepts
Candidates must know screening and access control, the security restricted area, the sterile area, and the role of the airport security committee. The operator and the airport share responsibilities, and the State provides oversight. Threat and risk assessment underpins proportionate measures.
Unlawful interference
Unlawful interference includes hijacking, sabotage, and attacks on aviation facilities. The Tokyo Convention addresses jurisdiction and the powers of the aircraft commander; the Hague Convention makes hijacking an extraditable offence; the Montreal Convention covers violence against persons at airports and destruction of aircraft. States must prosecute or extradite.
Traps
Examiners blur Annex 17 with Annex 9 (facilitation) and mix up the three conventions. Another trap suggests that Annex 17 is optional or that screening is solely the airport's duty. Watch for questions on the commander's authority under Tokyo, which is limited and does not authorise arbitrary detention.
Rule of thumb
Match the instrument to the act: hijacking → Hague 1970; offences on board and commander's powers → Tokyo 1963; violence at airports and sabotage → Montreal 1971/1988.
