Woods, it seems to me you have some kind of allergic reaction to my posts. Calm down, please.

Just pointing out, again, that Crew Dragon interior really is as uncluttered as shown in the mock up and crew trainer, because people keep insisting that the Crew Dragon interior cannot possibly be as clean as shown in the mock up.

During the ascent phase the crew really isn't crew. They are passengers. The entire ascent to orbit is fully automated, including all the abort modes. No silly abort-mode switches or joysticks (a la Shuttle) or manual abort handles (a al Apollo). None of that stuff. Are you sure? I believe CCT-REQ-1130 requires crew to have the ability to manually trigger ascent abort, or manually turn off auto abort. I said switches, joysticks and handles. None of that stuff is on Crew Dragon. A touchpad is however. And yes, the manual over ride option for ascent abort is there, but the odds of it being used is extremely low because the computer is way quicker and monitoring a helluvalot more system- and performance parameters than are being presented to the crew on the main display. The option is there because of a NASA requirement with a likelihood of being used equal to zero. Manually turning off auto abort is only applicable BEFORE an abort is triggered. It cannot be used to terminate an abort option that is in the process of being executed. The option was added because NASA considered that there could be a very unlikely repeat of an Apollo 14 scenario.Could you remind me what happened with Apollo 14?

After separating from the Command Module in lunar orbit, the LM Antares also had two serious problems. First, the LM computer began getting an ABORT signal from a faulty switch. NASA believed that the computer might be getting erroneous readings like this if a tiny ball of solder had shaken loose and was floating between the switch and the contact, closing the circuit. The immediate solution — tapping on the panel next to the switch — did work briefly, but the circuit soon closed again. If the problem recurred after the descent engine fired, the computer would think the signal was real and would initiate an auto-abort, causing the ascent stage to separate from the descent stage and climb back into orbit. NASA and the software teams at the Massachusetts Institute of Technology scrambled to find a solution, and determined the fix would involve reprogramming the flight software to ignore the false signal. The software modifications were transmitted to the crew via voice communication, and Mitchell manually entered the changes (amounting to over 80 keystrokes on the LM computer pad) just in time.
CCT-REQ-1130 and it's 297 pages is just one reason I have suggested SpaceX keep NASA at arms length on BFS...
Released three more pics from CD training mockup interior, taken on Aug 2 in JSC.Two central seats evidently tilted down on leg side, missing seat belts, handles or hand rails, camera holders, etc. Some temporary black squere bars supporting side seats... I of couse love this spacious and clean interior very much, but a bit of fine tuning / outfitting is still pending, I suppose.
Also I wonder whether "pilot(s)" will have some emergency buttons/joystick directly on the arm rest of their seats

I of couse love this spacious and clean interior very much, but a bit of fine tuning / outfitting is still pending, I suppose.Coming back to your post again.Have a look at the recent image of the inside of the Starliner Crew Trainer (below). Note the lack of camera holders? As well as the lack of handles and hand rails?The reason is similar as for Crew Dragon. There are no requirements for having handles, hand rails or camera holders.The only mobility assist are the black ropes with handles being suspended from the ceiling. Those are used only during crew ingress in 1G (prior to launch) and are removed (stowed) when ingress is complete. They don't bother removing them in the Crew Trainer because astros and technicians are getting in-an-out of there all the time.Quote from: pospa on 08/11/2018 05:56 pmAlso I wonder whether "pilot(s)" will have some emergency buttons/joystick directly on the arm rest of their seatsClearly no buttons or joysticks on the arm rests in Starliner either. And looking at some of those seats: what arm rests?(the Boeing seats look rather uncomfortable when compared to the Crew Dragon seats)The reason is the same as for Crew Dragon: no requirements for spacecraft controls located on the seats.
What handles and hand-rails? They aren't needed. People in 1G can get in-and-out just fine with what you see in the photos. And you don't need handles in zero-G. The cabin is so small that a wall, ceiling, floor or seat is always within arms-reach of an astronaut.I suggest you review on-board ISS footage. Notice the hand-rails in the modules? Now notice how often they are used by crew.They mostly aren't.The crew moves around by ever so slightly pushing off from (with feet and hands) whatever surface they have under reach.
I noticed that in the recent pictures of the interior, there where just four seats in the Dragon 2 Trainers. I do remember earlier pictures showing up to three additional seats. Were those nixed? When this was done? Or is it that there is a planned flexibility to make the interior with more seats in case needed?
....Easily done in fact. NASA has no need for BFR/BFS. It has SLS/Orion.....
Crew Dragon media day in Hawthorne, California.

Wasn't there talk of something to enable a single Dragon to evacuate a 7 person crew?
