Aircraft serial number 20.004 has joined the E2 test fleet. The jet is the 4th E190-E2 prototype flying in the E2 certification campaign. This particularly aircraft has a full-production interior and will be used primarily to evaluate cabin comfort and noise levels and to conduct evacuation tests.
The three other E190-E2 prototypes have accumulated 650 flight hours, one third of the requirement for certification. Embraer has completed tests for short take-off and landing, climb performance, in-flight thrust determination, landing gear stability and other systems tests. Currently, the E2 prototypes are being prepared for high speed flying qualities, flutter, natural ice and cold soak.
Testing with the four flying E2 prototypes is in addition to some 30,000 hours of ground tests on fatigue and static test aircraft. An iron bird features all aircraft systems in full scale, including the cockpit, and allows Embraer to simulate flights for the E175-E2, E190-E2 and E195-E2. The comprehensive campaign will ensure a more mature airplane upon entry into service.
The E2 program is tracking on target. The first E190-E2 is on schedule to be delivered in the first half of 2018 to Widerøe of Norway.
