Embraer is investigating reports of GPS instability affecting some aircraft, including its E2 family, after the issue disrupted operations at Brazilian carrier Azul. The affected aircraft include the E190-E2 and E195-E2, and the main operational impact has been flight delays, cancellations and aircraft-on-ground situations rather than any safety risk.
The problem has been linked in reporting to Honeywell’s Primus Epic 2.0 avionics, though the underlying cause has not yet been publicly confirmed. Embraer has been working with operators and the equipment manufacturer to resolve the disruption and provide technical support. The company has also maintained that the E2 fleet can continue operating during GPS instability because it carries alternative navigation systems and procedures.
Azul, which operates a large E2 fleet, adjusted its network and schedules after the disruption emerged. Reports indicated that some aircraft were temporarily grounded and that the condition could return after a system reset, prompting further operational caution across the fleet.
