## Key Insights
|
| 180 |
|
| 181 |
| Insight | Detail |
|
| 182 |
|---|---|
|
| 183 |
+
| **Wind & Visibility are independent** | Near-zero correlation — either alone can ground a mission. Monitor both separately. |
|
| 184 |
+
| **Humidity is an early warning signal** | Above 90%, visibility reliably drops below 4 km. Predict groundings before they happen. |
|
| 185 |
+
| **Snow is disproportionately dangerous** | ~40% higher grounding risk than rain despite lower frequency. |
|
| 186 |
+
| **Seasonality is predictable** | December/January are ~30× riskier than July. Plan resources accordingly. |

## Limitations

| 191 |
|
| 192 |
- `Mission_Status` is **rule-based**, not naturally observed — engineered from predefined thresholds that may not capture all real-world operational nuance.
|
| 193 |
- Results reflect **associations**, not causal relationships.
