GPS Instability Grounds Embraer E2 Flights and Forces Major Schedule Changes

Overview

• Operators reported a global loss of GPS on Embraer 190/195 E2 jets that disrupted operations late Tuesday, Sept. 22 and led to dozens of canceled flights and aircraft taken out of service.
• Azul said it canceled more than 70 flights and that roughly 15,000 passengers were affected, and the airline is adjusting its schedule while providing passenger assistance under Brazil’s ANAC rules.
• Embraer confirmed it received multiple reports, opened a crisis room with Honeywell and is supplying technical support to operators while investigators seek the root cause.
• The manufacturer says a system reset can temporarily restore GPS but the condition has recurred, and it stresses that E2 aircraft have redundant navigation systems and procedures that preserve flight safety.
• The event has created aircraft-on-ground (AOG) situations that can cascade into wider schedule disruption and regulators, carriers and suppliers will be watching for a permanent software or hardware correction and new operational guidance.
