Default CNv Vario Software Update (6/7/13)

The great thing about software control of parameters is
that one can change them; a simple program for the PC to change sime basic
settings would be good.
I have downloaded a recent uprgrade but there remains for me
two items which need attention.

1. changing the short climb smoothing to something which
better reflects a fuill circle
2. control of -ve and -ve audio thresholds to provide a dead band.

Changing any setting in flight ( unless you are alone in wave)
is distracting and potentialy dangerous; eg changing the
MacCready value.

a really valuable addition would be an output for a zero reader
for cruise. ( faster slower) the sinking audio tone is inaudible
behind the airflow noise. A small vertical scale meter can be installed on
the instument cowl well forward.; no need to refocus.
I had such an indicator on a vario-computer made for the
1970 WGC and it was very useful.

These days one could have array of LED s under a cowl
instead of a meter ( with intensity control), maybe blinking to register in
the peripheral vision; anything to replace constantly referring to the
vario.

Evan now has something to work on.
Please give me a zero reader output!
