Final Glide Calculation over Obstacle

[[email protected]]

I would like to use the Cambridge 302 and 303 but have questions:

1- does it calculate the glide path above obstacles, e.g. a mountain
is in the way: does the CAI 302/303 see the path going through the
rocks or does it see that there is a challenge?

2- is there a possibility to see the characteristics or profil of
thermals depending on height - like the Zander does?

3- is there a "move waypoint"-function for AAT tasks with calculated
new estimated time of arrival and such like in LX7007 or Zander ZS1?

Which calculators or software can all do this?

I like the CAI 302/303 very much, because it as a concise manual and
the menues of the two seam to me very intelligently designed.

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.

CAI does not do that you need to couple it with PDA/software. GPS_LOG
program does 1 and 3. It does not show 2, but provides related
information.

SN10 does 2 (dedicated graphic page of thermal strength vs height) and
3 (albeit a bit difficult to move the turnpoint inflight for "what-
iffing").

PDA/SeeYou Mobile does 1 and 3 (easy - a couple of taps on the
screen), but not 2 (it does give history of themal strength, though).
