NAC-Dynamic Friction Decelerometer (NAC-DFD®)

The NAC-DFD® is an electronic friction testing device designed for airport runways. This 3-axis mobile iOS™ application enables airport operators to "spot-check" contaminated surfaces during winter runway operations.

Key Features:

Accurate Measurements: Records vehicle braking values by measuring the "g" force or lock-wheel braking action during qualified tests.

Automated Reporting: Automatically generates final reports segmented into runway thirds: "touchdown," "midfield," and "rollout."

Comprehensive Data Recording: Captures all necessary data, including time, date, operator, and assigned user ID.

Versatile Contaminant Selection: Allows operators to choose from 14 different contaminant types for reporting runway conditions during winter operations.

Easy Data Export: Supports exporting results using the standard print function.

Additional Information:

The NAC-DFD® assists airport operators in assessing the effectiveness of friction-enhancing treatments by indicating trends in runway friction levels. It is approved by the Federal Aviation Administration, as listed in Advisory Circular 150/5200-30C, Appendix 3.

Note: For continued testing, a subscription is required.
