As I reflect further, the Nautical Almanac Sight Reduction tables also work from the DR, so no AP is needed there either. So my statement should be modified to state that "the AP is a convenience for the use of some tables to reduce sights."
Yes, that's better. The sight reduction methodology of Bennett's The Complete Onboard Celestial Navigator also uses the DR position.
