Boeing started Function & Reliability (F&R) testing and extended operations (ETOPS) demonstrations on the 787 Dreamliner. This is the final phase of flight testing prior to certification of the airplane.
F&R testing simulates various normal and non-normal operations for the airplane, in a realistic airline-like flight environment. ETOPS refers to extended operations – for twin jets, flights that are more than 60 minutes away from a suitable landing field. During ETOPS demonstrations the company validates the airplane’s ability to safely divert for a variety of reasons, including long diversions with one engine shut down.
In addition to F&R and ETOPS testing for the 787 with Rolls-Royce engines, Boeing continues certification testing on 787s with General Electric engines and will conduct a separate F&R/ETOPS test program for that version of the airplane. Other activities will continue on the flight test fleet to support Boeing objectives including examining potential technologies for the 787-9 and testing engine improvement packages.
