Flight test confirms Embraer E2 jet’s eco-credentials


Results from the latest flight tests of the Embraer E190-E2 narrow-body jet have exceeded its original specification and show it is more efficient than any other single-aisle aircraft, the Brazilian aircraft manufacturer has said.

The 114-seat E190-E2 is a medium-range twin-engine jet. It is expected to be certified during February.

In terms of fuel consumption, the tests showed that E190-E2 is 1.3% better than originally expected, a 17.3% improvement when compared to the current generation E190, and nearly 10% better than its direct competitor. 

The E190-E2 was also found to have the lowest level of external noise and emissions in its aircraft segment. The cumulative margin to ICAO Stage IV noise limit increases from 17EPNdB to 20EPNdB, which is 2EPNdB better than its direct competitor.

Rodrigo Silva e Souza, vice president of marketing at Embraer Commercial Aviation, said, “When our first operator, Widerøe, operates its inaugural E190-E2 flight on April 24 from Bergen to Tromsø, it will be the first in-service flight of the world’s most efficient and eco-friendly narrow-body jet. This is an immense achievement for our team and means additional value delivered to our customers.” 

Flight test results also confirmed improvements to the jet’s take-off performance and range. The aircraft’s range from airports with hot-and-high conditions, such as Denver and Mexico City, increases by 600 nautical miles compared to current generation aircraft. Meanwhile, its range from airports with short runways, such as London City, also increases by more than 1,000 nautical miles, allowing the aircraft to reach destinations like Moscow and the north of Africa. 

Pilots of current generation E-jets will only need 2.5 days of training and no full flight simulator to fly an E2. “Decreasing the training burden for pilots transitioning from E1 is another huge reduction in both time and cost for our operators. This, coupled with the E2 family’s world leading fuel efficiency and lowest noise footprint, makes the E2 the most cost effective aircraft in its segment by every measure”, said Silva.
