this scenario happens more than you think.
(landing in the dark on a home strip)
I know of a guy who thinks nothing of having the wife park on the downwind end of his strip, hazard lights flashing and high beam pointing down the runway.
lands over the top of her in absolutely crap weather.
has done it many times.
in my little garmin gps I can set the display to show an "ADF" needle or a "CDI".
I use the simple ADF (automatic direction finder) needle on the display but I wonder in cases like these if the CDI (course direction indicator) doesn't offer a better display since the offset from the straight-line track is also indicated.
might have told this guy he was off to the side of the intended track.
