Two versions of the Boeing 787 have been in service for a while. However, development activities continue. The 787-10 is still undergoing flight test but work also continues on the older jets. Some of this is also related to the Dash 10. I had a post on my first encounter with the 787-10 which I wrote about here. I have since come across another of the test aircraft. This one is plain white and doesn’t benefit from the nice house colors that Boeing has.
Meanwhile, one of the 787-8 test aircraft has recently been testing the newest version of the Rolls Royce Trent 1000. I saw this engine when it was being tested on Rolls’ testbed in Tucson and that was in this post. Now it has been fitted to its intended platform and is undergoing trials. These have included lengthy flights around the US including one in which they traced out the planform of the aircraft across multiple states. If you are going to go flying for 18 hours, you might as well find a way to have fun with it. The aircraft is carrying the same logo on the engine nacelle that was on the testbed. Hopefully, the delayed upgraded engine will soon be in service, not just on the Dash 10 but also on the other variants.
