Embraer (EMB, São José dos Campos U.E. Stumpf International) reported a GPS system instability impacting certain aircraft, including its E2 family, on September 23, 2026. It is collaborating to monitor the situation, as carriers such as Azul Linhas Aéreas Brasileiras and KLM Royal Dutch Airlines have been forced to ground parts of their fleets and make operational adjustments.

Despite the issue, the manufacturer said there is no impact on flight safety.

“The global E2 fleet is equipped with navigation systems and procedures that allow the aircraft to operate even under conditions of GPS system instability,” the company told Reuters in a statement.

Meanwhile, Honeywell Aerospace, whose equipment is fitted on the impacted aircraft, said it was aware of the issue and was “actively assessing the matter” to identify the underlying cause.

Embraer Technical Services released a bulletin instructing carriers how to implement a temporary fix, but a permanent solution had not yet been achieved. "A system reset has been reported as a temporary solution to restore normal GPS signal reception; however, the failure condition may occur after the reset," it warned.

ch-aviation fleets data shows a total of thirty-seven E190-E2s and 182 E195-E2s are at commercial airlines worldwide, with Porter Airlines Canada, Azul, and KLM Cityhopper being the largest operators of the aircraft family. The Brazilian carrier said the GPS issue grounded about a third of its overall fleet on September 23.

In Canada, Porter Airlines also cancelled a series of flights that were scheduled to operate on E2 jets, as did European companies such as KLM, Binter Canarias, and Luxair.

ch-aviation has reached out to Embraer for an update on the issue. It was not immediately available.
