Hazards, risk and learning from change
Original educational synthesis of selected historical passages. Not an operational procedure, licensing checklist or substitute for current approved documents.
Separate the concepts
A hazard describes a condition or object with the potential to contribute to harm. Risk considers possible outcomes rather than merely naming the condition. Keeping these ideas separate helps explain why identifying an issue and deciding what to do about it are related but different activities.
An ongoing process
The inspected Safety Management Manual describes safety risk management as continuous because aviation systems change. Identification, assessment, mitigation and acceptance connect with checking whether controls remain effective. An educational example is a change in workplace layout: a learner can ask what has changed, who is affected and what evidence would help evaluate the change, without prescribing an operational risk assessment.

The historical Annex 19 passage quoted on its reference page connects reactive and proactive hazard identification. Reports of past events are therefore only one learning input. Looking at change and emerging conditions also matters. This does not justify assigning generic risk scores from a website; an organization’s approved methods and competent people are needed.
State and provider roles
Annex 19 also introduces the State safety programme. A State’s system of oversight and a service provider’s safety management system operate at different levels. Understanding their relationship helps learners distinguish regulation, oversight and day-to-day organizational safety work. The local second edition is historical, and a newer third edition is listed by ICAO.
