Update the DR Plot

Jargon that means transfer your course changes from the logbook to the plotting sheet so you can figure your present DR position. The chart and plotting work of dead reckoning. In practice, this process can take more time than the actual sights and sight reductions. It can be done more efficiently and accurately using a programmed calculator that does dead reckoning. See Dead Reckoning, DR Plot, DR Position, Logbook, Plotting Sheets, and Calculators.
