Semaphore Sam says: "...On plotting chart, there is a section which, for every 10 degrees east-west of passage, you can plug in the north or south coordinates (ie, 54N to 52N), and get a distance and initial course. This allows for checking accuracy of programmed waypoints; gross errors become obvious..."
Are you an old Navigator who brings along one historic CR6 whiz-wheel and plotter and actually dabbles with True course, drift and distance between wayponts?
When we fly an assigned Track we keep it simple: We don't make a mountain out of a molehill. We only connect the waypoints on a plotting chart with a pen or pencil. Then we periodically double check our position by pushing "Hold" on the individual INS or GPS units...which normally are triple-mixed into the FMS...which is coupled to one of the Auto Pilots. We are only concerned with our
actual position relative to our assigned Track. We don't get creative about Variation and about comparing TRUE versus MAG values. And during a crossing I actually spend more time reading popular magazines. Yawn.
