I feel sorry for the poor mechanic who had to do all the work of re-stowing the RAT, only to see it pop out again and again. Big grin

Good job though Boeing. Nice to see it getting so close to flight!

RAT

Ram Air Turbine. it deploys from the fuselage to provice electric or hydraulic power or both in case of dual engine failure or all generator off.

Ram air turbine. Supplies hydraulic power when both engines are out (e.g. no fuel).

Is it normal to deploy TR only on one side?

My guess is that they will test the left side next.

It's normal to test one system component at a time before you test them all in tandem.

One component at a time... ground power until each tests out fully.

Once all things test, then the intermediate gauntlet will run.

They will use ground power for all the various functional tests. APU hasn't been started yet AFAIK. They use ground hydraulic power too for many functional tests!

Quoting DocLightning (Reply 12):

Typically work like that is done inside the factory on other Boeing models. I'm not sure why it is being done at the field.



If you have never designed an airplane part before, let the real designers do the work!

The APU has been spooled up but only ran for 15 minutes. I think they did that while it was still at the fuel dock.

The aircraft appears to be holding to plan right now with with several program sources indicating the first start of the aircraft's twin Rolls-Royce engines could be as little as hours away.

Not exceptionally difficult, just tedious to do it over and over. On other Boeing's i.e. 767's and 757's it barely takes 5 minutes.

ATW ran an article on the 18th saying the engines were planned for start on the 17th.

Geoffrey was basing it off Jon Ostrower's earlier report that engine start tests were to occur on the 17th. Jon said he had made a mistake with regards to the engine start date and corrected himself and now states that the engine start tests are supposed to take place either today or tomorrow depending on the weather.

See Jon's two reports:

It's interesting because the article says that Boeing "planned" to start the engines on the 17th but makes no mention of the fact that it never happened. It should have been mentioned IMO.

Especially since they want early frames for expansion into Europe, so it looks like the first tranche of production aircraft won't be as "hobbled" as some have stated/opinioned. And since they want all 18 and this is a "major expansion", it cannot be a case of JQ putting 787-8s on shorter routes to free-up their six A330-200s for the new missions. I am guessing this will be via BKK?

Why shouldn't airlines want the early frames? I know the news about the first ones, but look at the 77As, all frames found an airline. The 77As are still good USA East-Coast - Europe TATL airplanes.
Boeing has just to find a customer who takes a bunch of the first frames and the problem is solved, perhaps JQ is that customer...
