Re: Touchscreens have their place
>>>Did the manual throttles have 2 levers in 2 different places on the bridge to do the same? No?<<<
No, not on the bridge, secondary control stations are normally far enough away to be not affected by a single impact. Warships have had duplicate controls for for throttle & steering since it became possible to do that in the 19thC (also for weapon control). The expectation in a warship is that enemy action will cause damage and duplicated systems allow the ship to be remain viable in combat and not so susceptible to a single lucky hit.
For the tanker, touchscreen is not an issue as theres no duplication (single engine, single screw) and no expectation of trying to control the ship in anything more than a rough sea.
