HARD-BRAKe landings
Identify runway hotspots with aircraft braking performance data
What hard-brake landings tell you
Hidden signals of degrading runway conditions
ABARnet™ issues a Hard-Brake Landing (HBL) report for specific runway segments when hydraulic pressure reaches ≥1400 PSI on both main gears for 3+ seconds.
In practice, it means a pilot pressed harder on the brakes than normal during a rollout. This could be done:
Because the runway is slick from rain, snow, ice, or rubber buildup
To make a quick exit and reduce taxi distance, saving time and fuel
When landing on a short or high-altitude runway
Due to runway design flaws (e.g., grading)
Operational impact
HBLs are a frequent signal of where runway performance is slipping, so maintenance teams know where to act before operations or safety is compromised.

More movement.
Faster recovery.
Fewer disruptions.
Knowing where HBLs occur creates cascading advantages:
to focus on the exact spots that need attention — where, when, why, and how.
with more accuracy to restore and/or enhance braking action performance.
with improved maintenance scheduling and fewer disruptions to operations.
with data identifying the root causes of delays — degraded runway conditions, traffic, weather, or more.
