ADS-B broadcasts aircraft position worldwide with no authentication — and GNSS spoofing corrupts it. The attacks, the documented incidents since 2022, and why there is no quick fix.
EFB operational safety: lithium thermal runaway containment, failure & redundancy policy, human factors and common-mode risk — plus AI-era EFBs from 2026 on.
How the industry defends EFBs: DO-326A/ED-202A airworthiness security, MDM hardening, signed chart data, AID isolation and continuous monitoring.
The EFB attack surface mapped: device tampering, chart data poisoning, AID attacks, malicious updates and supply chain — with real published aviation research.
EFB regulatory framework explained: FAA AC 120-76E/AC 91-78A, EASA AMC 20-25, ICAO Doc 10020, OpSpecs, Part-IS — and the operational approval process step by step.
From AIRAC cycle to cockpit: the complete EFB data pipeline — chart production, ground distribution, connectivity options, sync and version control.
Type A, B and C EFB software explained — from document viewers to certified performance tools. How failure effects drive aviation software classes.
Class 1, 2, 3 EFB hardware explained — plus how AC 120-76E replaced classes with portable vs installed. Displays, AIDs, buses, power, mounting.
