Friday attendance seemed lighter than last year. Blame Thunderstorm Morning! One downpour sent sheets of water an inch deep flowing across the exhibition tarmac. *** But nothing dampens sky-bound enthusiasts for long — before long, we drowned rats re-emerged and started aviating as the skies slowly cleared and sunlight finally popped out around 4 pm. *** Highlights of my day: *** * Robert Hamilton of Dynon Avionics took me through a quick tour of the new Skyview System avionics platform. Very impressive. *** Their number one seller: the FlightDEK-D180, closely followed by the original EFIS-D10A, which fits into 3 1/8″ hole — ideal for retrofitting a steam-gauge panel for a complete flight system or to backup a big-panel EFIS system. *** Safety feature: The D-10A has a 1-hour battery life. Even if you lose all electrical power in flight, you can have instruments for landing.
