ICAO PBN Symposium Regulatory and Certification Forum Safety

ICAO PBN Symposium Regulatory and Certification Forum Safety case – procedure ready for publication? Jeff Cochrane, Manager CNS Service Design

NAV CANADA SMS Certification • Private, non-share capital corporation • 2 nd largest ANSP in the world – 12 million aircraft movements – Over 18 million square km of airspace – 4, 900 employees • Regulated by Federal Government on Safety Performance • CARs Part VIII, Subpart 5 Requirement for Safety Management System to be in force January 1 st, 2008 • Phased in over four years and completed this year 2

Mission Statement NAV CANADA facilitates the safe movement of aircraft, efficiently and cost effectively, through the provision of air navigation services on a long-term, sustainable basis. Overarching Objectives 1. 2. 3. 4. 5. 6. Maintain a safety record in top decile Maintain ANS customer service charges in bottom quartile Implement and maintain a modern, cost-efficient technology platform in the top quartile Ensure a decline in customer service charges over the long term Create a productive and fulfilling workplace, placing us amongst top Canadian employers Identify and, where feasible, introduce measurable benefits which contribute to the reduction of the environmental footprint of the aviation industry.

Operational Risk Management Safety Management System Safety Planning Operational Risk Management Exchange of Safety Information Safety Performance Measurement Safety Management Assurance Operational Risk Management The systematic and effective application of suitable risk-management techniques, employing system safety and human factors concepts to reduce the safety risks resulting from the provision, by NAV CANADA, of air navigation services and products to a level as low as reasonably practicable (ALARP).

Safety Management Checklist

Hazard Identification and Risk Analysis (HIRA) • Multi-disciplinary brainstorming • Systems approach to hazard identification – – People Procedures Equipment Operational environment • Best practices for indentifying and mitigating operational safety hazards and risks related to technical and human performance

RISK The product of probability and severity

Constraints and Assumptions • General • ATC Based • Customer Based

Hazards • Hazard - A latent condition or circumstance that could lead to or contribute to one or more undesirable outcomes. • Defined in terms of: – – – – Context Description Causes Outcome Probability x Severity = Risk Mitigations - effect on “P x S = Risk” Residual risk is ALARP

Hazard Table – Mitigation Table • Mitigation - Measures taken to reduce risk by eliminating a hazard or reducing the probability and/or severity. • Mitigation measures complete when the residual risk is ALARP. • Matrix of mitigations across hazards

SMS success when: • We have a clear understanding of the technical, operational and organizational factors that affect safety – Current issues – Potential safety risks that could result from business and operational changes • We implement appropriate and effective mitigation – e. g. design of airspace, level of service, integration of flight deck with ATS services & products, design of systems/functionality, design of procedures, training programs, staffing, policies, procedures, instruction, supervision, briefings, alerts

Summary Implementing new PBN procedures touches all disciplines requiring a focused effort of consultation supported by SMS processes
