- Description
- A secondary flight deck barrier is a lightweight device that is easy to deploy and stow, installed between the passenger cabin and the cockpit door that blocks access to the flight deck whenever the reinforced door is opened in flight for rest breaks, meals, etc. This will reduce the vulnerability of another 9/11 type attack in which an airliner is commandeered by terrorists, kept under control for some time, and then crashed into a specific target. Our risk-based framework is published in important, peer-reviewed journals: Risk Analysis and Journal of Policy Analysis and Management, and it was included in our 2018 book, How Safe is Safe Enough? Measuring and Assessing Aviation Security. We systematically and transparently apply standard risk-analytic and cost-benefit methods, ones that are routinely applied throughout the world. We use the standard definition of risk adopted by the DHS and TSA where the reduction in risk is the degree to which the security measure foils, deters, disrupts, or protects against a terrorist attack. A security measure is cost-effective when the benefit of the measure outweighs the costs of providing the security measures. Our results are based on robust systems reliability analysis and cost-benefit assessments. We find that secondary cockpit barriers are highly costeffective: Very effective: The secondary barrier reduces risk by up to 15%. Total risk reduction from all layers of aviation security then exceeds 99%. ; Modest cost of only $5 million per year for entire US commercial airline fleet. ; $10,000 each annualised for 6,000 aircraft over 15-20 year service life. ; Break-even analysis shows that even if there were only one terrorist hijacking attack in a thousand years (annual attack probability of 0.1%) and the terrorists arrived at the airport undeterred and undetected, secondary barriers would still be cost-effective. ; The benefit-to-cost ratio is a high 41 – $1 of cost buys $41 of benefit (lives saved, damage averted. ; Cost effective even if risk reduction is reduced by a factor of ten and costs quadruple.
