Overview

Analytical study models safety targets and risk apportionment in aircraft transport, highlighting benchmark navigation requirements for airspace integration.

Key Points

To develop a universal safety assessment and risk apportionment framework applicable to both manned and unmanned aircraft transport operations.
Reviewed and compiled existing aircraft classifications, operational services, and regulatory performance specifications into a standardized catalog.
Identified critical gaps in universal safety evaluation across varying operational environments.
Formulated a mathematical risk-apportioning methodology to derive required navigation performance parameters (accuracy, integrity, continuity, and availability) under the most stringent service conditions.
Determined a standardized alert limit benchmark of 3 m for demanding aircraft transport operations.
Established a baseline safety target threshold of 1.0 × 10⁻⁵ failures per flight hour, noting that operational stringency scales with specific flight phases.
