Why it matters
Without it, unanticipated runway conditions and degraded braking performance can lead to AOG events, aborted landings, or safety occurrences during critical phases of approach and rollout.
From design to safety
Design
AI-driven risk model concept
Design defines data interfaces for runway performance, safety margins, and regulatory requirements; specifies sensors, inputs, alert thresholds, and data lineage to support flight operations, SMS governance, and phase-appropriate certification activities.
- landing distance
- crosswinds
- braking action reports
Build
Prototype integration and validation
Build validates end-to-end data feeds from landing distance, approach speed, crosswind estimators, and braking data; performs acceptance testing against performance targets, interface contracts, change control, and regulatory compliance; generates release notes and traceability.
- approach speed
- performance data
- crosswinds
Operation
Real-time risk assessment during flight
Operation consumes live braking actions, surface condition feeds, and distance-to-go; computes excursion risk score, updates cockpit guidance, and delivers dynamic fallback procedures and alternate-route prompts.
- landing distance
- braking action reports
- performance data
Maintenance
Data integrity and calibration
Maintenance monitors sensor health, recalibrates landing distance and crosswind measurements, verifies ground performance reports, reviews AD/SB impacts, runs model refreshes post-service bulletin, and maintains data lineage for CAMO.
- landing distance
- crosswinds
- performance data
Safety
SMS and regulatory alignment
Safety validates excursion risk outputs, preserves traceability to flight records, and confirms conformity with CAMO, Part-135/Part-145 safety processes, and audit requirements; closes safety loops with corrective actions.
- braking action reports
- approach speed
- performance data

- inconsistent brake pressure or pad wear indicating degraded braking
- AI action
- alert for potential braking efficiency loss and propose maintenance action
- 4
approach speed transducer
- Watch for
- deviations from target approach speeds due to wind shear
- AI action

- 5
braking action report interface
- Watch for
- gap between reported braking action and observed runway friction
- AI action
- triage to maintenance for surface condition data validation
- 6
performance data recorder
- Watch for
- unusual trends in acceleration, roll, or stall margins during approach
- AI action
- feed risk model with current aircraft performance metrics to recalc approach plan
Worked example
Catching a low-friction runway before a charter touchdown
Illustrative scenario with sample data.
A mid-size business jet detects degraded braking action and higher than expected landing distance on a damp runway ahead of a charter.
Signal in
landingDistance=2200 ft, crosswinds=12 knots, brakingAction=medium, runwaySurface=wet, approachSpeed=145 knots, performanceData=normal prior 10 flights, tirePressureFront=190 psi, tirePressureRear=185 psi
System out
riskScore=high; recommended actions: reduce approach speed to 142 knots, extend flare window, assign alternate runway, document in TOLD; alert flight crew and CAMO; log incident in safety report
Human sign-off: Director of Maintenance reviews and approves action plan; records in maintenance release and safety log; CAMO validates data for release to service; accountable manager signs off on mitigations
How to roll it out
Phase 1
Weeks 1 to 2
Baseline data model; identify core sensors and data feeds; establish data governance, traceability, and data quality metrics.
Phase 2
Weeks 3 to 6
Prototype integration with flight ops and maintenance planning; pilot testing in simulators and limited revenue flights; validate alert thresholds and UI prompts.
Phase 3
Weeks 7 to 12
Operational rollout with dashboards; formal CAMO and Part-145 release processes; EMS alignment; set change-control and incident-reporting routines.
Where people stay in charge
- All excursion risk decisions must be approved by a certified senior aircraft engineer or CAMO for regulatory compliance and safety accountability.
- Actions affecting flight operations must be reviewed by the flight operations manager and authorized by the accountable manager as part of the approved risk management plan.
- The CAMO must retain audit trails for all AI-generated advisories, including data sources, decision rationales, and change history, for regulatory inspection and safety assurance.
Questions owners and crews ask
What data feeds are used for runway excursion prediction?
The system reads landing distance measurements, approach speed trends, crosswind estimates, braking action reports, runway contamination data, rainfall data, tire pressures, and performance data from flight and maintenance records; it processes this to assess risk and guide actions.
Who signs off on AI-generated safety actions?
A qualified Part-145 certifying engineer or accountable CAMO signs off on recommended actions, followed by appropriate maintenance orders or flight plan changes, with records filed in CAMO and maintenance logs.
Can the system trigger automatic flight crew alerts?
Yes, it can generate cockpit advisories and automated checklist prompts; final actions require pilot confirmation or regulatory-approved automation limits and crew response documentation.
How is data kept auditable?
All data streams, decisions, and actions are time-stamped and stored in the aircraft’s log, the CAMO records, and the maintenance management system for audits and reviews.
