Are We Safe Enough? Measuring and Assessing Aviation Security explains how standard risk analytic and cost-benefit analysis can be applied to aviation security in systematic and easy-to-understand steps. The book evaluates and puts into sensible context the risks associated with air travel, the risk appetite of airlines and regulators and the notion of acceptable risk. It does so by describing the effectiveness, risk reduction and cost of each layer of aviation security, from policing and intelligence to checkpoint passenger screening to arming pilots on the flight deck.

Key Features

  • Quantifies the risks, costs and benefits of various aviation security methods, including policing, intelligence, PreCheck, checkpoint passenger screening, behavioral detection, air marshals and armed pilots
  • Focuses on security measures that reduce costs without reducing security, including PreCheck, Federal Flight Deck Officer program and Installed Physical Secondary Barriers
  • Features risk-reduction insights with global applications that are fully transparent, and fully explored through sensitivity analysis


Aviation practitioners tasked with securing, organizing, planning, budgeting, and managing, as well as Aviation policy makers and graduate students in aviation security, planning, management, economics and operations
