NAVIGATION

1. in actual fact real navigation is the science of recognition of positions and objects and estimation of relative distances and angles between them. (HCO PL 18 Sept 67) Navigation (Def. 1) 2. man tends to avoid confronting the real and so invents symbols as substitutes. This goes to the extent, in navigation, of making fun of direct observation navigation, preferring calculation by symbols. Real navigation methodology by definition (other planet) is navigate by direct observation of visual contact. In the absence of this seek to predict and establish position by a minimum of symbols and vias until visual contact can again occur. (FO 40)
