Maybe I didn't express myself clearly enough. If you attach rockets, bombs or AG missiles to one of the stores and then start the F-16C cold and dark, the CAT switch is preset to CAT III. If, on the other hand, I only attach external fuel tanks, regardless of whether they are on the wing or center, the switch is set to CAT I. The manual says something different:
To continue this consistently, during a cold and dark start, even if only 1 fuel tank (i.e. no additional armament) was attached, shouldn't the switch already be preset to CAT III?
