    Re: Averaging
    From: Chuck Taylor
    Date: 2004 Oct 22, 16:31 -0700

    Herbert Prinz and I appear to be in disagreement over
    two points regarding US Power Squadrons (USPS)
    courses:
    
    1. The acceptability of "high-altitude sights" (over
    75 degrees in altitude) in the JN course.
    
    2. The requirement for averaged sights.
    
    On item #1, Herbert is correct.  The requirement
    changed between JN-89/92 (in which high-altitude
    sights were not admitted) and JN-99 (in which
    high-altitude sights are discouraged, but
    admitted).  Interestingly enough, I have never seen
    a JN student submit a high-altitude sight, before
    or after the appearance of JN-99.  In any event,
    I never reject a sight without checking the reference,
    so I would almost certainly have caught my error
    had such a sight been sent to me for grading.
    And if I hadn't, USPS has a grading system under
    which any sight disqualification must be reviewed
    by a second person before it becomes official.
    
    My apologies to Herbert for my error.
    
    As to item 2, the requirement for averaged sights,
    I wrote:
    
    > >  One run of 5 averaged sights is
    > > required for the Navigation course, but averaged
    > > sights are not otherwise admitted.
    
    and Herbert responded:
    
    > Nowhere in the manual do I find such a rule. Please
    > give me the
    > reference with page number. My manual demands 3
    > sights in a run, but no requirement for averaging.
    
    Please note carefully that I said the "Navigation"
    course.  I believe that Herbert is referring to the
    "Junior Navigation" course, or JN-99.  USPS offers
    *two* celestial navigation courses, "Junior Navigaton"
    and "Navigation".  Herbert is correct that nowhere in
    the "Junior Navigation" course student manual, JN-99,
    is there a requirement for sight averaging.
    
    There is, however, a requirement for sight averaging
    in
    the "Navigation" course student manual, N-99, and it
    is
    on page 1-4 of N-99 (paragraphs 28 through 32).
    
    So, it appears that Herbert and I were writing about
    two different courses.
    
    Best regards to all,
