    Lon off a bit.
    >2.  TC to 52 30 S 100 00 W = 109, distance = 932 nm.
    Diff probably due to Lon above
    >3.  Compass course = 82.
    Same as 2, above
    >4.  DR Mar 17 0250 Z = 47 42 S 121 20 W.
    Same diff in Lon
    >(the following answers I have not posted before)
    >
    >5.  Fix at 0250 Z = 47 03 S 118 28 W.  DR was way off.
    Diff on Lat off slighly. Lon off, but diff is less.

    You are off slightly, but if you were navigating using 211 and plotting
    on a plotting sheet it would be a NORMAL difference in FIX position
    between any two navigators.
    >7.  Time after 81 hours = Mar 20 1150 Z, 0450 ZT
    OK
