Aviation Safety
Safety management and risk
Modern safety thinking moves from reactive accident investigation to proactive hazard identification. Know the safety management system (SMS) components: safety policy, safety risk management, safety assurance and safety promotion. Understand the difference between a hazard (a condition with potential to cause harm) and a risk (the combination of likelihood and severity). Know the Swiss cheese model, the difference between active failures and latent conditions, and the importance of just culture.
Threat and error management
Understand TEM: threats are external events, errors are pilot actions or omissions, and undesired aircraft states are the result. Countermeasures include briefing, cross-checking, monitoring and assertive communication. Know the role of voluntary reporting systems and why they succeed when punishment is removed.
Traps
Examiners test the hazard/risk distinction, the components of SMS, and the purpose of a just culture. A common trap is treating a low-probability, high-severity risk as acceptable simply because it is rare. Another is confusing safety assurance (monitoring) with safety promotion (training and communication).
Worked example / rule of thumb
Rule of thumb: assess risk as likelihood × severity; if either factor is high, the risk needs mitigation before flight. Use the TEM loop: anticipate threats, trap errors early, and recover to a stable state.
Study strategy
For each safety concept, write one operational example from your own flying; examples make the definitions stick.
Emergency Procedures and Crew Resource Management
Emergency procedures
Know the priorities: aviate, navigate, communicate. Understand the memory items for engine failure, fire, rapid decompression, and rejected take-off, and when to use a checklist. Know the difference between an emergency and an urgency, the declaration on 121.5 MHz, and the transponder codes. Understand evacuation, ditching and survival considerations, and the importance of briefing passengers.
Crew resource management
CRM covers communication, leadership, teamwork, workload management, decision-making and situational awareness. Know the difference between autocratic and democratic leadership styles and when each is appropriate. Understand the role of the briefing, the sterile cockpit rule, and how to speak up effectively - using the aircraft call sign, stating the concern, and offering a solution.
Traps
Examiners test the order of actions in an emergency: control the aircraft first, then diagnose, then communicate. A common trap is choosing to troubleshoot before flying the aircraft. Another is assuming that a captain's decision cannot be challenged - effective CRM requires challenge when safety is at stake.
Worked example / rule of thumb
Rule of thumb: in any emergency, the first action is always to maintain aircraft control, then set a known attitude and power, then run the checklist. For speaking up, use the three-part formula: state the observation, state the risk, propose the action.
Study strategy
Rehearse memory items aloud with a partner, then run the checklist; the sequence must be automatic before the checklist appears.
