I would like to use the Cambridge 302 and 303 but have questions:
Which calculators or software can all do this?

The 302 won't do all that, the 302/303 won't do all that, the 302 with
PDA and suitable software may do all that.

GlideNavII does not do 1 or 2 and does a poor job of 3 if there is
significant wind.
