The Global Standard in Emergency Recovery Technology
The Runway Safe BAK-12 stands as the U.S. Air Force standard for aircraft recovery. Engineered for uncompromising reliability, this hydraulically actuated rotary friction energy absorber safely arrests hook-equipped aircraft during emergency landings or aborted take-offs.
Whether deployed in permanent high-traffic airfields or remote expeditionary environments, the BAK-12 provides a self-contained, bi-directional solution. Pilot safety and asset preservation are ensured under the most demanding operational conditions.
Engineered for Every Engagement
- Bi-Directional Versatility
Supports precautionary approach-end engagements and standard overrun-end arrestments. - Adaptive Performance
An integrated hydraulic control circuit automatically adjusts brake pressure based on aircraft weight, engagement speed, and off-center positioning, up to 40% of semi-span. - Operational Throughput
The standard configuration supports up to 6 engagements per hour. Enhanced models, featuring brake cooling systems and 65 HP retrieve engines, increase capacity to 20 aircraft per hour. - Climate Resilient
Proven performance in Arctic, desert, and tropical environments, with an operational range of -40°C to +52°C.
How the BAK-12 Works
The BAK-12 uses a velocity-sensitive braking philosophy to manage kinetic energy safely.
- Standby mode.
A static pressure system maintains precise hook cable tension in the battery position. - Engagement.
As the aircraft pulls the tape, rotation of the tape reel drives a hydraulic pump and cam-actuated valve. - Dynamic braking.
The pump generates pressure proportional to the aircraft’s velocity. A shuttle valve transitions the system from static (dynamic) to hydraulic (braking pressure) within 120-200 ft; (36-60 m) into the arrestment - Optimized deceleration.
A field-adjustable cam profile regulates brake pressure throughout the arrestment. The result is a smooth, programmed stop tailored to specific aircraft weight ranges.
