HARD-BRAKe landings
Identify runway hotspots with aircraft braking performance data
What Hard-Brake Landings tell you
A Hard-Brake Landing (HBL) occurs when extra braking is applied by the pilot during a rollout. ABARnet™ reports an HBL when hydraulic pressure reaches ≥1400 PSI on both main gear for at least 3 seconds.
In practice, it means a pilot pressed harder on the brakes than normal. Why? It could be:
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)
HBLs happen far more often than friction limits. That makes them a frequent, valuable signal of where runway conditions may be degrading — and where airports should act before safety or operations are compromised.
A complete picture of runway surface conditions
Unlock runway intelligence with braking data not found in conventional reports:
HBLs are mapped to precise runway segments and taxiways, revealing degraded surface conditions and braking action patterns that traditional inspections often miss.
By revealing hotspots and patterns from traffic, weather, or design, HBLs allow airports to continually refine treatment schedules and maintenance strategies — so they can maximize runway uptime.

More knowledge.
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.
