lennonvarmistuksen

Lennonvarmistus (flight safety assurance) is a Finnish term for the set of processes, services, and practices that ensure the safety of civil aviation operations. It encompasses planning, execution, and monitoring of flight operations to prevent accidents or incidents and to ensure compliance with applicable laws and standards. Lennonvarmistus relies on information flows such as weather data, NOTAMs, airspace notices, and flight plans, and on services including air traffic control, flight information services, and surveillance. Core activities include risk assessment, safety management, development of standard operating procedures, training and competency management, incident reporting and safety performance monitoring. The approach emphasizes a proactive safety culture and continuous improvement through audits, investigations, and safety recommendations.

In Finland, lennonvarmistus is implemented within a framework that aligns with international aviation safety practices. Regulatory oversight is provided by the Finnish Transport and Communications Agency (Traficom), while Finavia operates the national air navigation services infrastructure. Airlines, airport operators, and other aviation stakeholders implement their own safety management systems and comply with EU and ICAO requirements. The concept supports both routine operations and crisis response, including weather disruptions, airspace restrictions, and contingency planning.

The term reflects the broader field of aviation safety and is closely linked to related areas such as air traffic management, safety management systems (SMS), and incident reporting. International standards from ICAO and European regulations from EASA guide national practices and enable harmonized safety performance across operators and infrastructure.
