Aircraft manufacturer Embraer has released the final results of the E190-E2 aircraft flight tests ahead of its certification.

The flight tests have confirmed that the new-generation narrow-body jet is better than its original specification and was also found to be more efficient than other single-aisle aircraft.

In fuel consumption, the E190-E2 performed 1.3% better than original expectations, representing a 17.3% improvement compared to the current generation E190 aircraft.

“Decreasing the training burden for pilots transitioning from E1 is another huge reduction in both time and cost for our operators.”

With the lowest level of external noise and emissions, the new aircraft was also found to be the most environmentally friendly aircraft in the segment.

Embraer commercial aviation marketing vice-president Rodrigo Silva e Souza said: “This means that when our first operator, Widerøe, operates its inaugural E190-E2 flight on April 24th from Bergen to Tromsø, it will be the first in-service flight of the world’s most efficient and eco-friendly narrow-body jet.”

Flight test results also confirmed that the E190-E2 is better in take-off performance than its original specification.

The range of the aircraft from airports with hot-and-high conditions increases by 600 nm compared to current generation aircraft, while its range from airports with short runways increases by more than 1,000nm.

The E190-E2 also secured better results in a pilot’s transition training time in comparison to initial expectations.

Pilots of current generation E-Jets will require 2.5 days of training and no full flight simulator to fly an E2.

Silva e Souza added: “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, make the E2 the most cost-effective aircraft in its segment by every measure.”

Embraer also stated that E190-E2 exhibited longest maintenance intervals in the single-aisle market with 10,000 flight hours for basic checks.
