Uss Fitzgerald Collision


Recommended Posts

Brutal, as the kind of reporting done by ProPublica is going to move the needle of public and political opinion based on its credibility.

 

The Navy and Pentagon's public relations offices are going to be working overtime on this one.

LEADERSHIP: KILLER APP

"The U.S. Navy has concluded that one of the factors that led to three warship collisions in 2017 was the adoption of touch screen controls for ship navigation."

 

"... none of the crew involved were able to quickly take control and avoid the collision. Further complicating the situation was the fact that the officers and sailors involved were suffering from lack of sleep and experience with emergency use of the SCC. So the navy is converting back to the traditional manual controls, which are more intuitive and familiar."

Touches (no pun intended) on a concern I have about all the touch screen controls on the new crew vehicles being built for NASA. The old vehicles had toggle switches with guards around them so that you could only use them if that was your intention. I could see a situation where the vehicle is shaking around during launch or some such, the crew touching the touch screen but hitting the wrong button due to the movement, an option popping up "do you really want to blow the hatch?" or some such and then they go to hit the cancel button but the craft lurches again and they hit "confirm" and that's the end of that. It might work great in a static simulator but have they dealt with the mis-touch concern in reality? I don't even want to think about all of the inadvertent touches from floating around in zero G all day.

Touchscreens and moisture do not mix if the way my phone reacts to that combination it is any indication. The question for the GAO is now one of reporting for the public record how extensive the implementation of touchscreen navigational control has been in the USN, and the cost to be paid for reversing it.

Capacitive displays do not like moisture, but for any rougher use than toying around resistive displays are being used. Basically the screen is one big switch with two foils that are pressed together with your finger. Disadvantage is that it can only register one finger at a time, but it works with anything that can press on the screen. https://en.wikipedia.org/wiki/Resistive_touchscreen

 

 

Jeff's concern is IMHO valid though, because you can still uninteninally touch something. Or some tool floats against a screen etc.

Panicked jabbing of such a touchpad with the kind of force induced by the clenched knuckle fear of impending combat or collision could certainly register more dangerously than in peacetime.

 

Moderately heavy seas could complicate the panicked jabbing motions of 0.5" squares on a touchpad further.

 

How much of the blame for collision after collision that may be placed on such technical factors will be as interesting as they may be convenient.
