Company reported 5 deaths per 10,000,000 passenger miles. If the average speed of the airplane is 200 miles per hour, please calculate the FAR and fatality rate. Assume average miles per trip is 300 miles. Please compare your results with the Table 1-4. Should you be worried to happy to fly with ABC airlines? In Table 1-4, please assume fatality rate of car is similar to air TMEF: Target mitigated event frequency TO: Threshold Quantity Severity Risk Matrix 1. Select the severity from the highest box in either of columns 1, 2 or 3. Read the Category and Safety Severity Level from the same row. 2. Select the likelihood from columns 4 thru 7. 3. Read the Risk Level from the intersection of the severity row and the likelihood column. 1 Human Health Impact Public fatality possible. employee fatalities ikely Employee fatality possible. Major injury likely Lost time injury (LTI) likely Recordable Injury b. A leak of 2,000 kg of octane results in an explosion with a financial loss of $900,000. The last incident of this type occurred 9 years ago. Use the risk matrix to determine the Severity Category, the Safety Severity Level and the Risk Level.

Risk Level B: Undesirable risk, additional safeguards must be implemented within 3 months. Risk Level C: Acceptable risk, but only if existing safeguards reduces the risk to As Low as Reasonably Practicable (ALARP) levels. Risk Level D: Acceptable risk, no additional safeguards required.
