    Oh. I wondered how you got GHA, LHA or declination when only one leg and one
    angle are given, and no time.  Must be a way, but it is above my head.
    Which leaves me with a pocket calculator, watch, sextant and almanac and the
    knowledge an HC and azimuth, and my best guess of 90/270d, is better than a
    time sight.
