- AAI -- "all-ahead standard," normal cruising speed, more energy-efficient than AAII
- AA2/3 -- "ahead two-thirds," slow, used for hazards
- AA1/3 -- "ahead a third," very slow, used for docking
- Z -- "all stop," no motion
- B1/3 -- "back a third," very slow reverse
- B2/3 -- "back two-thirds," slow in reverse
- BF -- "back full," fastest sustainable in reverse
- BE -- "back emergency," maximum power in reverse, often unsustainable"
AA = All Ahead, B = Back
Just for grins:
" All Ahead Bendix - Traditionally, an engine order for "max tracks," i.e. as fast as she can go. The Engine Order Telegraph (q.v.) was traditionally made by the Bendix Company, and was so marked just past the forward end of the annunciator quadrant. Therefore, pushing the E.O.T. annunciator handles as far forward as they would go brought the pointer near the word "Bendix." Actual use of "All Ahead Bendix" tends to irritate the Chief Engineer." |
I know what you're saying. So it's wrong on SH3 the line "All ahead 1/3" that is shown on the screen when you press "2".
What I find weird is that seems to be wrong, mathematically.
Suppose the ship max speed was 20 kts: All ahead 2/3 would give you around 7 kts, which is basically one-third of the max speed. Two-thirds would be 66%, or 14kts.
But anyway... who am I to argue with the navy?
