Aviation Security: understanding what is required for new avionics/aircraft development and operations via the new mandatory DO-326A/ED-202A documents. In this introductory “Guide for the Perplexed”, attendees will get a crash-course on the new “DO-326/ED-202 ecosystem” of emerging regulation.

The DO-326A/ED-202A set of documents is all about the mitigation of the aviation/aircraft safety effects of “Intentional Unauthorized Electronic Interaction (IUEI)”, a.k.a. “Cyber Threats”, and which were explicitly excluded from the classic DO-178/ED-12/ARP4754 set.

DO-326A/ED-202A & DO-356A/ED-203A focus upon type certification during the first three phases of an aircraft (including avionics) type: 1) Initiation, 2) Development or Acquisition, and 3) Implementation. Their companions DO-355/ED-204 focus upon security for continued airworthiness.

DO-326A/ED-202A currently has 3 (three) companion documents: ED-201, DO-355/ED-204 and DO-356A / ED-203A, and a few more planned. DO-326A / ED202A provide requirements and objectives in a similar fashion to DO-178C, DO-254, and ARP4754A; while the DO-326A guidance is just that, certification authorities increasingly assess DO-326A compliance as added requirements for aviation suppliers.

The DO-326A/ED-202A set currently applies to fixed-wing aircraft (Part 25), with clear FAA recommendations for the adaptation/tailoring of DO-326A/ED-202A for general aviation (Part 23),rotorcraft (Parts 27 and 29), engines (Part 33) and propellers (Part 35), and clear indications of it will increasingly being applied to these other aircraft including military beginning in 2022 or thereafter.
