    Haversine scales on slide rules
    From: Bill Ritchie

    Brian, In your  2024 May 30, 01:59 -0700 post, you said "Perhaps as I have suggested, navigation slide rules should have haversine scales, to minimise movements."

    In response to posts on navigation slide rules by Bob Goete and Sean Johnston around five years ago, I created a configurable slide rule emulator and saved examples tailored to their preferences.  The scale choices list included three haversine scales, in anticipation of your above comment!
