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]. Alan Wilson Canberra. 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... http://www.onlinecontest.org/olc-2.0/gliding/flightbook.html?sp=2015&st=olcp &rt=olc&pi=22975 and most of my logs since 2006 are from car GPS. Logs from an SNAV are often rejected! -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Ron Sanders Sent: Monday, 01 December, 2014 1:17 AM To: Discussion of issues relating to Soaring in Australia.
