Secure Avionics Update: Patch Management and Safe Software Delivery for Airborne Systems
Updating avionics software is not a routine maintenance task it is a high-stakes engineering operation where any failure can compromise safety, mission capability, and regulatory compliance. Modern aircraft rely on increasingly complex digital components, and keeping these systems secure and up to date requires a tightly controlled patch-management pipeline built around cryptographic trust, verification,…

N-Version Programming and Design-Fault Tolerance in Safety-Critical Actuators
Safety-critical aerospace systems demand reliability far beyond ordinary software engineering standards. In modern fly-by-wire architectures, actuators that drive control surfaces — elevators, ailerons, rudders, flaps, and high-authority maneuvering systems — must function correctly under all circumstances. Hardware redundancy alone cannot guarantee this; design faults in software remain a major threat. This is where N-Version…
