Ah, I see. So then you're saying that if you are in NYC you can see
Philadelphia on a clear day, since they are only around 80 miles apart.
Very good. You nailed that one.
An ICBM has no navigation system.
"ballistic" means "ballistic"
Ah, I see. So then since the ICBMs are in the silos pointing straight
up and they have no navigation system, then the only thing they could
ever possibly hit is the silo that launched them. Very good. You
nailed that one too.
There's no outside reference when using DR to navigate.
deduced reckoning is navigating by compass and knot log. neither are outside
references as to position
Ah, I see. So a compass works without any outside reference, i.e., the
Earth's magnetic field. Very good. You nailed that one too and are
doing very well.
It costs $15,000/year to make 10gals of water/day with a shipboard
watermaker.
Don Casey says it is a dollar a gallon. The cost accountants would give the
higher figure, in the context of the problem under then discusssion.
Ah, I see. So 10gals/day at $1/per gal equates to $15,000/year. Very
good. You nailed that one too. You really are a whiz and are 4 for 4.
Care to try the rest?

The human head can take about a 7 G blow before death becomes certain.
A rhumb line is a straight line on any chart, Mercator chart (sic) or
otherwise.
A rhumb is distance between two points one compass point apart.
Alternators are (for all practical purposes) capable of only producing
one voltage, no matter the rpm.
If you can see outside reference points, then you KNOW where you are...
There is no such thing as a north seeking gyro.
