Abstract: DEAR SIR : In your journal for March 1947 (NAVIGATION. Vol. 1, NO. 5, pp. 111-12), J.1. Green discusses the influence of the earth’s rotation on bubble-sextant readings, and concludes that the correction to be applied depends on the course of the aircraft as well as on the latitude. The implication is that the Z-table published in the American Air Almanac (which is a slight extension of that in the British Air Almanac) is incomplete.
