The Premier DRFC-1 IFR Radio Facility Chart Plotter has 13 scales for Jeppesen Radio Facility and NACO Charts.

The plotter shows a compass rose for quick course and bearing information and a color-coded illustration for parallel, teardrop, and direct entries to standard and non-standard holding patterns.

Use the plotter's sawtooth nautical mileage scales to differentiate between graduations. Two slots and two holes make it easy to mark and plot courses on en route IFR charts.

Available scales are as follows:

One inch = 5, 6, 7.5, 8, 10, 12, 15, 16, 20, 30, 38.5, 40, and 48 nautical miles.

An international kilometer to nautical mile conversion scale is printed on the plotter.

Instructions for use are included. Durable plastic, 6” x 3 ½”. Lifetime Guaranteed.
