This modification ensures the warning works correctly, preventing pilots from accidentally following faulty signals that could lead them dangerously off course."}},"importantCases":[],"_links":{"self":"/api/acts/ad-rad-6-bendix-vhf-nav-receivers-flag-alarm-and-deviation-circuit-modification","history":"/api/acts/ad-rad-6-bendix-vhf-nav-receivers-flag-alarm-and-deviation-circuit-modification/history","analysis":"/api/acts/ad-rad-6-bendix-vhf-nav-receivers-flag-alarm-and-deviation-circuit-modification/analysis","conflicts":"/api/acts/ad-rad-6-bendix-vhf-nav-receivers-flag-alarm-and-deviation-circuit-modification/conflicts","importantCases":"/api/acts/ad-rad-6-bendix-vhf-nav-receivers-flag-alarm-and-deviation-circuit-modification/important-cases","documents":"/api/acts/ad-rad-6-bendix-vhf-nav-receivers-flag-alarm-and-deviation-circuit-modification/documents"}}
