NAC DFD Case Study

NAC's Dynamic Friction Decelerometer (DFD) is an electronic 3-axis device used to “spot-check” a contaminated surface during winter runway operations. The DFD's software program records vehicle braking values by measuring the “g” force, or lock-wheel braking action, when the vehicle operator completes a qualified test. This easy-to-use software program automatically creates the final report of the runway thirds, “touchdown”, “midfield”, “rollout”. Operators can then select from a list of 14 different contaminate types used within the NOTAM reporting system to provide a detailed report of the conditions. NAC's DFD connects to any mobile data PC device (not included) and has a 2-year manufacturer's warranty.
