摘要:
A digital navigation instrument primarily intended for the general aviation pilot. The navigation instrument combines the functions of a calculator and a stopwatch and provides a method of easy reference to a navigation chart. The resulting unit provides ease of data entry from the navigation chart and ease of alternation between time interval measurement and arithmetic calculations.
