Embraer’s new E190-E2 jet has not yet reached the market and has already been “perfected”. According to the director of the aircraft development program, Fernando Antonio Oliveira, the aircraft exceeded some of the performance expectations foreseen in the original project.
In addition, Oliveira also confirmed that the manufacturer is “a few weeks” to complete the certification of the jet with regulatory bodies, a process that frees its debut in commercial aviation.
“We have achieved more than 98% of the flight test campaign,” the Embraer director said in an interview with Aviation Week. “We have some remaining tests, mainly interior inspections and some flights with pilots from the certification authorities.” The most recent tests were carried out on January 18, with maximum braking assessments and control tests of new generation PF & P turbofan engines PW1900G, certified in the United States in 2017.
With the testing campaign close to being completed, the E190-E2 presented a performance in fuel consumption, range, pollutant emissions and noise level that exceeds the objectives foreseen in the original project.
In 2013, when it launched the E-Jets 2 program, Embraer pointed out that E190-E2 would be 16% more efficient in fuel consumption compared to the current E190. After testing, the number jumped to 17.3%, which consequently increases the range of the aircraft.
The director of Embraer also highlighted the increase in the autonomy of the new jet from airports with short runways and in hot and high regions (Hot and High, in the jargon of aviation), which represent a great challenge for aviation (high-altitude operations). temperatures in high regions require aircraft with specific profiles).
According to the manufacturer’s calculations, the 1.3% improvement in fuel consumption of the E190-E2 will allow the reduction of some 1,700 tons of CO2 emissions over 10 years.
Embraer also achieved a cumulative noise margin (from taxiing and take-off procedures, cruising flight and landing approach) 3 EPNdB (effective noise perceived in decibels) lower than expected, reaching 20 EPNdB. The number respects the most recent noise regulations of the FAA, the United States Aviation Authority.
