kev600,
You are right that when you ring Stand By for the Port engine on the starboard telegraph, the engine room answers with Dead Slow Ahead. (20 RPM) This is true only for the “Ahead†Stand By.
This problem doesn’t occur with the port telegraph when ringing for Stand By on the Starboard engine.
As for the throttle, as you point out, it works on different increments from the telegraphs. It is not practicable, then, to control the telegraphs via the arrow keys in a rational manner.
Returning the throttle to zero does result in 0 RPM because it sets both telegraphs to the “astern†Stand By position.
I don’t understand Orinoco’s statement that the telegraph for the Port engine is backwards.
It is the mirror image of that for the Starboard engine so that pushing the handles forward rings forward (which is intuitive). Were the actual telegraphs configured in a non-intuitive fashion?
Sorry, Orinoco, I just looked at the pic in your post, and it is backward there. Your pic must have been pre V1.1, or else the tooth fairey fixed mine.
