Coupled Feedback Oscillation
Runaway Resonance & Unbounded Corrective Amplification
Automated stabilization or risk-mitigation routines introduce phase-shifted corrections that amplify the exact perturbation they were designed to damp, causing runaway resonance.
Correction latency matches the characteristic period of the disturbance, transforming negative feedback (stabilizing) into positive feedback (explosive divergence).
Domains Historically Vulnerable
Primary Invariant Primitives
Derived Structural Failure Patterns (2)
Single-Sensor Flight Control Trim Runaway
Flight augmentation software (MCAS) repeatedly trims stabilizer nose-down based on a single faulty angle-of-attack vane, overwhelming manual pilot yoke counter-effort.
Automated Market-Maker Liquidity Withdrawal Cascade
Large sell algorithmic order triggers risk-limit thresholds across automated market makers, causing simultaneous quote cancellation and an instantaneous liquidity vacuum.
Verified Public Incident Dossiers (4)
Lion Air Flight 610: MCAS Angle-of-Attack Runaway Oscillation & Pilot Muscle Fatigue
Automated stabilization routine commanded persistent state modifications driven by single corrupted sensor. Human Decision_Node counter-actions were repeatedly overridden by recurring loop iterations until physical control buffer depleted.
Ethiopian Airlines Flight 302: MCAS Repeated Activation & Unrecoverable Manual Trim Forces
Automated feedback loop repeatedly forced control surfaces into extreme deflection. When human Decision_Nodes disabled electrical automation, aerodynamic airload physics locked manual mechanical override, depleting altitude Buffer_Reserve.
May 6, 2010 Flash Crash: Algorithmic Feedback Void & 1 Trillion Dollar Liquidity Evaporation
Stabilization algorithms with identical risk-mitigation rules executed simultaneous quote cancellations. The collective withdrawal amplified the price collapse exponentially, draining the entire market buffer reserve.
Knight Capital: Dead-Code SMARS Flag Execution & $440M Loss in 45 Minutes
Asynchronous deployment divergence left one Decision_Node running deprecated logic under repurposed telemetry flags. The unconstrained automated loop flooded State_Telemetry channels with 4M orders, consuming the entire firm capital reserve in 2,700 seconds.
