"steve", plugs are plugs, in the world of engines. anything else is
everything
else, and is named such.

You say that after cofusing plugs with "spark" plugs. You're just as
confused as always. That 6.9 G blow to your head must be showing it's
effects. Of course, if it were a 7 G blow, you wouldn't have survived
(according to you.)

plugs are plugs. everything else is something else.

DR means deduced reckoning, except to those people who think "dead on" means
kinda about maybe possibly close by or maybe not.

Ah, I see. So all plugs are spark plugs. Is that your final answer? lol

Wrong again and still confused I see.
DR means "dead reckoning" or maybe "deduced reckoning", or maybe "ded
reckoning".... and these meanings can be different.
For people such as yourself, brought up on needing positions within 1-2
feet, it's understandable that you would not accept anything less as
"dead on".

BTW, you should see all the "plugs" on the engines of this diesel tug I
work with, none of which has anything to do with creating a "spark".

I think somebody is taking a beginning nav course.

Two references:

From the Dictionary of Nautical Literacy, published by International Marine ( a
division of McGraw-Hill)

Dead reckoning: The process of determining the position of a vessel by tracking
course and speed for a given time.
From the phrase, "deduced reckoning", the plot is called a "DR".

According to this source, Jax is half right. The process is called "dead
reckoning", but the hypothetical plot it produces can be called a "deduced
reckoning."

Then there's another source that indicates neither side of the argument has an
absolute leg to stand on:

From "The Sailor's Illustrated Dictionary"

dead reckoning (DR): The determining of a position by course, speed, and time
elapsed, but without a fix. A DR position is shownon the chart with a half
cirlce and a dot and the time the vessel was calculated to be in the position.
With any other information included, such as wind and current, it is called an
estimated position.
The term "dead reckoning" comes from "deduced reckoning" or "ded. reckoning",
which later became "dead reckoning."

According to this source, the hypotheticaly correct term realy is ded.
reckoning, (short for deduced). Unlike an assertion that anybody who knew squat
about navigation would never say "dead reckoning", those who are exposed to the
practice on an actual basis, in the real world rather than by reading about
boating, have probably never heard the technique called anything
except "dead reckoning."

feel free to check with a mechanic if you wish.

DR means "dead reckoning"

the word "dead" can not be used in the context of DR, except in ignorance.

"ded" is the correct term, "dead" is not.

This is a real issue, for those who think "dead" is correct will also state
that ded reckoning is "dead bang on center", as in completely accurate, which
is a physical impossibility.

As usual, you are misinformed.

hoary, are you saying that "dead bang on center" means horribly inaccurate?
