  TECHNICAL & OPERATIONAL TRAINING REPORT: GNSS INTERFERENCE (JAMMING VS. SPOOFING) 1. Executive Summary In modern A320 operations, the ability to distinguish between signal denial (jamming) and signal corruption (spoofing) has become a foundational competency for flight crews. While jamming represents a straightforward loss of navigation capability, spoofing introduces a more insidious threat: a "system lie." In a spoofing environment, the aircraft's automation may believe it is on the correct trajectory while silently steering the aircraft into danger. This report analyzes the shift from traditional system failures to these contemporary "un-alerted" anomalies. The primary risk has evolved from "clean" navigation downgrades—where the system identifies a lack of signal and reverts to backup sensors—to "un-alerted" map shifts that can induce uncommanded turns and spurious terrain warnings. Understanding these distinctions is critical to ma...

  Technical & Operational Training Report: A320 Air Data Reference (ADR) & Unreliable Speed Management 1. Executive Summary In the sophisticated architecture of Airbus Fly-By-Wire (FBW) aircraft, air data serves as the critical "nervous system." Precise measurements of airspeed, altitude, and Angle of Attack (AoA) are not merely for pilot display; they are the fundamental inputs driving flight control laws and envelope protections. For the modern flight crew, a deep understanding of the "Median Value" logic—the method by which the aircraft’s computers validate this data—is a primary safety barrier against automation surprises. The objective of this report is to move the training focus beyond the rote memorization of emergency checklists toward a deep technical understanding of ADR voting logic, fault isolation, and the Back-Up Speed Scale (BUSS). By evolving from a "button-pusher" to a "system-thinker," pilots can effectively manage high-...
