A350 MSN5 prototype will have fully-furnished cabins as the MSN2 that is currently flying. The test team will concentrate on MSN5 for analysis and specific range testing.
“MSN5 will be the first Batch2 airplane built with production-standard engines, and we will fly a 2 to 3 month test campaign on that airplane which is mandatory to certificate everything related to Batch2 modifications and the engines” said Fernando Alonso, Airbus senior VP Flight and Integrations Tests.
This aircraft will also be used for the route-proving program to be flown in conjunction with Qatar Airways from its Doha base, due to begin in the summer.
