    Is Sextant a generic word?
    From: John D. Howard

     This may sound like a silly question but do we use the word Sextant in a generic sense or as the name of a specific device - a double reflecting instriment with an arc of 60 degrees but reading to 120 degrees?

    The reason I ask is I have noticed many times on Navlist and in books that some people use the word Octant when talking about an aircraft instrement ( A-12 ) and sometimes Quardint. (and sometimes sextant )

    The Navy Mark II has an arc of 72 degrees and reads to 144 degrees but no one hesitates to call it a Sextant when it really is not.  Do we call a marine instrement a sextant and an aircraft device a quadrant?  Is there any agreement in the use of the different words?

    John H.
