I have to agree with Ian Mc Phee's  comment below: " I ask the question how
many electronic items do you have 20 years old?  Not  many I suspect. The
model 10 brick box is over 20 yrs old and most  model 20
 loggers are over 15 years old."   And the associated boxes require perhaps
3 @ 78 mm holes of valuable instrument panel space.  

Software and systems have made HUGE leaps since 1995.  A cockpit with a good
vario and a cheap PDA with XCSoar is a really effective arrangement. A $200
Nexus stand alone installation at $200 [JBHifi] does heaps more and much
more simply and meets most competition requirements. A $50 car GPS from Aldi
is good and easy to adapt.    Just bin systems that are more than 10 years
old and your life will be much simpler!      [of course the suck/blow ASI
and altimeter is retained].  Hard to see in sunlight, yes, but all I really
want is a Green up arrow on the LHS and I can see that.  All the other hard
to see numbers can be deciphered occasionally.

[If you really think you can beat a world record you will need to spend $$$
on certifications]

It is time for greater instrument panel integration.

What I would really like in one 58 mm hole is a new 'Smart'  vario that has
a NETTO option and outputs to a USB plug:  5 volts, NMEA data for airspeed
[yes airspeed]  into the Nexus7  [with a plug to integrate  FLARM ].  Anyone
got one? 

I don't want to muck around with IOIO and would be happy to have the FLARM
[audio and indicator] directly into the NEXUS 7 [or NEXUS 7 2017 update when
it is released].

PS. Then my simple instrument panel would look like: NEXUS 7, 'Smart' Vario
[or 2] on top, ASI, Altimeter below,  radio, with a FLARM box behind the
panel somewhere.   And do we really need a compass on manufacturers 'minimum
equipment' lists: it is almost 2015!

Tin Hat on...

an SNAV are often rejected!
