Default Not one person

you are right. it is a silly question.

shen, think about it. ******How******* did the radio compass get aligned?
duh.

shen, think about it for a minute. *Just ONE* of the issues is that a radio
compass is aligned using a magnetic compass.


Not exclusively, but you knew that.
So we're sure (you tend towards weird associations), you do mean that the
(usually, on small boats) relative bearing taken from the RDF is added or
subtracted, as the case may be, to the compass heading which is corrected to
magnetic bearing or to true bearing, prior to ploting?
Silly me, that's a question.


think about it? how many mag compasses have seen on boats that are accurate
to
2*?


Quite a few.


Think about it more. How many helmsmen on sailboats have you seen that

could
hold a course to 2* over any period of time?


Quite a few


Think about it. the error of the mag compass reading TIMES the error of the
helmsman gives the potential error UP TO THAT POINT. Already, you are
waaaaaaaaaay beyond 2*. waaaaaaaaaaaaaaay beyond.


You still haven't learned to use a compass for navigation, I see.
Times or plus, doesn't matter.
However, while following this thread it's become obvious that this is
probably
the best you could do.


Think about the additional errors associated with just the radio compass
itself
and its usage.


I see your reading is progressing.


think about it, shen.


I have. Your biggest problems revolve around the facts that you only know
what
you read, and have little if any understanding of the everyday "nuts and
bolts".
To continue to add to the list:
You don't know how to steer.
You don't know how to take bearings.
etc.
