# SmartScore Methodology

> Technical reference for the SmartScore composite safety metric -- pilot-level scoring, operator-level Insurer SmartScore methodology, pillar definitions, temporal smoothing, freshness tiers, and data firewall.

SmartScore is PlaneConnection's proprietary composite safety and operational quality metric. It operates at two levels: a **Pilot SmartScore** (0--100) for individual crew members and an **Operator SmartScore** (250--1000) for the organization. This reference covers both, with detailed methodology for the Insurer SmartScore derivative used in insurance underwriting.

<Note>
  SmartScore is a proprietary system. Factor categories and general methodology are published for
  transparency; specific algorithm weights and scoring formulas are not disclosed.
</Note>

## Pilot SmartScore (0--100)

The Pilot SmartScore evaluates individual crew members across three broad areas and combines them into a single overall score using a proprietary weighting model.

<Accordion title="Scoring Components and Weighting">
  | Component   | What It Measures                                                   |
  | ----------- | ------------------------------------------------------------------ |
  | Experience  | Depth and recency of flight experience.                            |
  | Proficiency | Currency of training, certifications, and demonstrated competency. |
  | Risk        | Safety event history and risk exposure over time.                  |

  Each component produces a sub-score. The three sub-scores are blended into the Overall Score through a proprietary algorithm that accounts for the relative importance of each dimension.
</Accordion>

### Score Ranges

| Band            |  Range  | Interpretation                                                       | Action Required                                          |
| --------------- | :-----: | -------------------------------------------------------------------- | -------------------------------------------------------- |
| Excellent       | 90--100 | Pilot demonstrates strong performance across all scoring dimensions. | None -- maintain current performance.                    |
| Good            |  75--89 | Pilot meets all standards with minor areas for improvement.          | Routine monitoring.                                      |
| Fair            |  60--74 | Pilot has notable gaps in one or more scoring areas.                 | Review contributing factors; consider targeted training. |
| Needs Attention |  0--59  | Pilot has significant deficiencies requiring intervention.           | Mandatory management review; action plan required.       |

### Fleet-Level Aggregation

The fleet SmartScore provides an aggregate view of pilot readiness across the organization.

| Metric            | Description                                        |
| ----------------- | -------------------------------------------------- |
| Fleet average     | Mean SmartScore across all scored pilots.          |
| Minimum score     | Lowest individual SmartScore in the fleet.         |
| Band distribution | Count and percentage of pilots in each score band. |
| Quarterly trend   | Score comparison against the previous quarter.     |

Fleet SmartScore appears on the safety dashboard and is included in quarterly management review data per 14 CFR 5.73.

### Pilot Detail View

| Element             | Description                                                            |
| ------------------- | ---------------------------------------------------------------------- |
| Overall Score       | Composite score with band indicator.                                   |
| Component Breakdown | Visual representation of Experience, Proficiency, and Risk sub-scores. |
| Trend History       | Score trajectory over the last 12 months.                              |
| Actionable Items    | Expired or approaching-expiry items with links to relevant records.    |

### How Scores Update

<Accordion title="Score Recalculation Process">
  SmartScore recalculates automatically in response to changes in the underlying data -- flight
  activity, training completions, safety events, and other operational inputs. A nightly batch
  ensures all scores remain current even when no individual triggers occur.

## Operator SmartScore (250--1000)

The Operator SmartScore assesses an organization's overall safety and operational quality. It exists in two forms:

| Aspect               | Internal SmartScore                                    | Insurer SmartScore                 |
| -------------------- | ------------------------------------------------------ | ---------------------------------- |
| **Purpose**          | Safety improvement coaching                            | Insurance underwriting support     |
| **Audience**         | Operator only (never shared externally)                | Shared at operator's discretion    |
| **Data sources**     | Zone A operational metrics + safety culture indicators | Zone A operational metrics only    |
| **Granularity**      | 15 dimensions, full detail                             | 4 pillars + composite (250--1000)  |
| **Update frequency** | Real-time                                              | Quarterly (90-day rolling average) |
| **Recommendations**  | Specific improvement actions                           | Not included                       |

### Score Bands (Operator-Level)

| Band                  | Score Range | Interpretation                                     |
| --------------------- | ----------- | -------------------------------------------------- |
| **Excellent**         | 850--1000   | Consistently strong performance across all pillars |
| **Good**              | 700--849    | Solid performance with minor areas for improvement |
| **Adequate**          | 550--699    | Meets baseline standards with notable gaps         |
| **Below Average**     | 400--549    | Significant areas requiring attention              |
| **Needs Improvement** | 250--399    | Material deficiencies across multiple pillars      |

## Insurer SmartScore Methodology

The Insurer SmartScore is a **4-pillar derivative** of the full 15-dimension Internal SmartScore, designed for insurance underwriting.

### Four Pillars

#### 1. Organizational Foundation

Structural elements that support safe operations:

* Years in operation and organizational stability
* Fleet size, composition, and aircraft age
* External certifications (IS-BAO stage, ARGUS rating)
* Certificate status and type

#### 2. Operational Excellence

Day-to-day operational quality:

* Maintenance compliance rates and overdue item counts
* AD compliance rate
* MEL usage patterns
* Dispatch quality and flight following coverage
* Route complexity management

#### 3. Safety Risk Management

Maturity of safety risk management processes:

* Reporting rate threshold (binary -- see below)
* Training completion rates
* Duty/rest compliance
* Presence of systematic safety processes

#### 4. Human Capital & Resilience

Crew qualifications, experience, and organizational capacity:

* ATP certificate percentage
* Average total flight hours
* Recurrent training completion rates
* Simulator training hours
* Crew currency rates

### Pillar Weighting

Each pillar contributes to the composite score with proprietary weighting. Weights are calibrated against historical loss data and adjusted through actuarial validation. The composite is not a simple average -- pillars interact, and certain deficiencies carry more weight than others.

***

## Temporal Smoothing

Insurer-facing scores use a **90-day rolling average** to prevent insurers from inferring safety events through sudden changes in operational metrics. Scores are delivered quarterly, not in real time.

This means:

* A single bad week does not drastically change your Insurer SmartScore
* Sustained improvements are reflected over the following quarter
* Short-term fluctuations are smoothed out

The Internal SmartScore updates in real time and is not subject to temporal smoothing.

***

## Reporting Rate Threshold

The reporting rate metric is a **binary threshold**, not a linear scale:

* **Meets healthy minimum:** >= 1 report per 10 employees per month
* **Below minimum:** fewer than this threshold

There is no additional scoring benefit for higher reporting rates. This prevents gaming (submitting low-quality reports to inflate scores).

### Quality Filters

Reports must meet quality criteria to count toward the threshold:

* Progressed to assessment or corrective action (not immediately closed)
* Assessment contains substantive content (minimum 50 words)
* Time-to-close is within normal range for the report category (not rubber-stamped)

Anomaly detection flags both sudden spikes and systematic low-quality inflation patterns.

***

## Score Freshness

Every score delivery includes freshness metadata:

| Age          | Status      | Insurer Guidance                                   |
| ------------ | ----------- | -------------------------------------------------- |
| 0--30 days   | **Current** | Acceptable for all underwriting decisions          |
| 31--90 days  | **Valid**   | Acceptable; recommended refresh for large policies |
| 91--180 days | **Stale**   | Warning; refresh before use                        |
| 180+ days    | **Expired** | Must not be used; require new report               |

Every response includes: `generated_at`, `valid_until`, `data_as_of`, and `freshness` enum.

***

## Granularity Tiers

Different audiences receive different levels of detail:

| Audience                     | What They See                                                                    |
| ---------------------------- | -------------------------------------------------------------------------------- |
| **Operator** (internal)      | Full 15 dimensions, sub-scores, all reason codes, improvement recommendations    |
| **Insurer** (standard)       | Composite score, 4 pillar scores, top 5 reason codes, confidence band, trend     |
| **Insurer** (summary)        | Composite score + trend direction only                                           |
| **Benchmarking** (aggregate) | Anonymized percentile band ("top quartile"), minimum bucket size of 15 operators |

***

## Reason Codes

Reason codes explain the top factors influencing a score, modeled after FICO credit score factors:

* **Top 5 positive** -- strongest contributing factors (e.g., "Fleet maintenance compliance rate exceeds 98%")
* **Top 5 negative** -- weakest contributing factors (e.g., "Three overdue maintenance items in trailing 90 days")

Reason codes are generated from the underlying dimension scores and use plain-language descriptions. They are included in standard-tier insurer deliveries and in all operator views.

***

## Confidence Assessment

Confidence reflects data completeness, not score quality:

| Completeness | Label                   | Confidence Interval |
| ------------ | ----------------------- | ------------------- |
| 80--100%     | **High confidence**     | Narrow              |
| 60--79%      | **Moderate confidence** | Moderate            |
| 40--59%      | **Limited confidence**  | Wide                |
| Below 40%    | **Low confidence**      | Very wide           |

A score with low completeness is **not penalized** -- the point estimate is unbiased. Low completeness widens the confidence interval, meaning the true score could be higher or lower than reported.

***

## Data Firewall (Zone A / Zone B)

The scoring engine accesses only Zone A data. Zone B data is physically separated:

| Category               | Zone | Score-Eligible | Examples                          |
| ---------------------- | ---- | -------------- | --------------------------------- |
| Fleet composition      | A    | Yes            | Aircraft count, types, age        |
| Flight activity        | A    | Yes            | Total hours, route complexity     |
| Maintenance compliance | A    | Yes            | AD compliance, overdue items      |
| Crew qualifications    | A    | Yes            | ATP %, average hours              |
| Training completion    | A    | Yes            | Recurrent rates, sim hours        |
| Dispatch quality       | A    | Yes            | Briefing rate, flight following   |
| Duty/rest compliance   | A    | Yes            | Violations, rest compliance       |
| Certifications         | A    | Yes            | IS-BAO, ARGUS, certificate status |
| Hazard reports         | B    | **No**         | Safety reports, near-misses       |
| Investigations         | B    | **No**         | Findings, evidence                |
| Corrective actions     | B    | **No**         | Remediation details               |
| NTSB notifications     | B    | **No**         | Reportable events                 |
| Confidential reports   | B    | **No**         | Identity-protected submissions    |
| Risk assessments       | B    | **No**         | Internal risk analysis            |

Zone A and Zone B use separate databases with separate encryption keys. The firewall is enforced through code-level import restrictions, automated testing, and lint rules.
