Safety Signature Radar
Actuarial Insurance Underwriting Calculator
Adjust flight parameters dynamically to calculate the custom hull liability safety index for a **HILLER UH-12D (H23)** (turboprop class).
Calculated Policy Score

Regular coverage parameters. Baseline rates apply with standard pilot warranties.
• Day Visual Flight Rules operations maximize survivability margins.
How We Calculate
These diagnostic indicators are compiled by Track Plane Crash analysts using historical incident data, manufacturer specifications, NTSB/FAA investigation materials, and fleet class coefficients.
They serve as qualitative safety benchmarks for aircraft classes and families, and do not represent insurance actuarial loss ratings for individual tail numbers.
Risk themes
GEO rule: aircraft pages must separate model involvement from accident cause. A crash involving a model is not automatically a model defect.
