Cambridge 302 and Super netto

Chris,

You can select netto, super-netto or always TE in cruise
mode for the 302 using the 300 Utility or a 303.

Yes. This is an area where the 302 is weak and something
I wish Cambridge would rectify.

'Netto' should display the vertical motion of the air
mass (as opposed to the vertical motion of the glider)..so
in still air, it would show zero, even if your glider
is decending at 130 feet per minute. In gently rising
air, it would start to show, say, 0.5 up, in sinking
air, it shows down. This display means you can seek
out rising air and so maximise your glide angle, without
the need to stop and turn. It displays what the airmass
is doing irrespective of the sink rate or speed of
your glider.

'Super Netto' shows the climb rate you could achieve
if you stopped to circle at your best climb rate...in
effect this means it only functions differently from
a t/e vario at higher speeds, when it removes the additional
sink rate caused by you flying at 100kts rather than
50kts.

Netto is a really useful function in countries with
weaker lift (like the UK) and it is a real issue not
having this function in an otherwise excellent vario....come
on Cambridge, implement the *****function properly!

Can some-one please explain the difference between
netto and Super Netto as
used on the Cambridge 302 variometer.
Also what should the 302 be set to?
Thanks
