Omega Chart Base Selection for Differential and Standard Use.

Abstract

Discusses the relationship between Omega errors and the choice of chart base and reviews the present choice. The error budget for Differential Omega is noted and the portion related to chart base identified. Optimum chart bases would be c/v=0.99691 during the day and c/v=0.99973 at night for a frequency of 10.2 kHz in the temperate latitudes. The best single velocity choice is c/v=0.9985. A chart base of c/v=0.9985 is recommended for Differential Omega at a frequency of 10.2 kHz. (Author)
