Navigation plotter

A navigation plotter for use with a chart having lines of latitude and longitude to determine distance, true course, speed, and fuel requirements for a trip, said plotter comprising a one piece, thin, light weight, plastic with a periphery including at least one straight-edge, said straight-edge having visible distance scales thereon, a reference point at the mid-point of said straight-edge, the remainder of said periphery having angular markings representing the degrees of a compass rose, said reference point being the center of said compass rose, further comprising said compass rose with a 70 degree reference line, said compass rose adapted to visually determine proper holding pattern entry, whereby said distance scales on said straight-edge designate the distance between two points and said angular markings indicate the true course when said reference point is placed on a line of longitude on said chart.
