    Re: Time of meridian passage accuracy

    You state that "the effect is very small as to be of no practical concern to practical navigators."
     
    I compiled a table in my Navigation paper showing differences between maximum alititude and meridian passage ranging from 10 seconds to 37 minutes. My trial which led me to write the paper had a difference of a minute and a half, and that was at a moderate latitude and sailboat speeds.
