The fourth prototype of the Embraer E190-E2 aircraft has completed maiden flight on last Friday, which lasted two hours.
The aircraft fitted with full interiors, is intended to be used for specific interior tests such as cabin evacuation, environmental comfort and internal noise.
The first three E190-E2 prototypes combined, have accumulated more than 650 flight hours to date.
“In terms of the certification campaign, Embraer has already frozen the aerodynamic configuration and concluded many tests such as flying qualities assessment, short field takeoff and landing, climb performance, in-flight thrust determination, landing gear stability and other systems tests. Shortly we will do high speed flying qualities, flutter, natural ice and cold soak tests,” explains Luís Carlos Affonso, COO, Embraer Commercial Aviation.
In addition to the flight test campaign, Embraer is performing more than 30,000 hours of ground tests as well as integration analysis.
With the goal of delivering a more mature airplane upon entry into service, the Company uses an Iron Bird, where all aircraft systems are available in full scale, including the cockpit. This tool enables Embraer to simulate flights of each E2 model and to optimize systems performance and refine flight qualities.
The first E190-E2 jet is on schedule to be delivered in the first half of 2018 and the launch operator will be Widerøe, the largest Norwegian regional airline.
