Reproducibility Package for the Risk-Aware UAV Safety Architecture (RASA) for BVLOS Operations

This reproducibility package accompanies the manuscript: "Risk-Aware UAV Safety Architecture (RASA) for BVLOS Operations: Formal Risk Quantification and Sensor–Communication Coupling" The package contains architectural visualisations, graphical abstract, model metadata, and supporting materials used to document and reproduce the Risk-Aware UAV Safety Architecture (RASA), a three-layer framework integrating multi-modal sensor fusion, SATCOM-enabled communication monitoring, and formal risk quantification for Beyond Visual Line of Sight (BVLOS) UAV operations. The framework quantifies operational risk using: R(t) = α·U_sensor(t) + β·L_c,norm(t) + γ·U_sensor(t)·L_c,norm(t) where U_sensor(t) represents normalised sensor uncertainty, L_c,norm(t) represents normalised communication latency, and γ represents the nonlinear coupling coefficient capturing compound sensor–communication degradation. Included materials comprise: - Figure 1 – Three-layer RASA system architecture and operational workflow - Figure 2 – Monte Carlo simulation results illustrating nominal, degraded, and compound-failure BVLOS operational scenarios, including γ sensitivity analysis - Figure 3 – Risk surface visualisation showing nonlinear risk escalation across sensor uncertainty and communication latency states - Figure 4 – Compound failure escalation scenario demonstrating risk amplification and Minimum Risk Manoeuvre (MRM) progression - Graphical Abstract summarising the complete three-layer RASA framework - RASA_Model_Metadata.txt describing model assumptions, parameter definitions, weighting coefficients, and risk-state classifications Version 2.0.0 updates: revised figure set expanded from three to four figures, corrected figure ordering to match the accompanying manuscript, updated title to align with peer-review submission wording, and description revised to reflect the explainable rule-based decision engine framing. This package supports transparency, reproducibility, and independent verification of the RASA framework for SATCOM-enabled BVLOS UAV operations.
