Hi,
after hours of testing the combination of SD and SkyEcho 2, I would like to say, that I am more than happy! First, I fly a vintage plane with no electrical system (no transponder etc.). So, until now I was completely blind and no one could see me, resulting in a couple of dangerous situations in the past. Now I use an Android Phablet, SD, SkyEcho 2 and Bose A20 Bluetooth as headsets.
The firmware of my SkyEcho 2 had to be updated after delivery. Then I subscribed the Flarm license and went flying. Binding the SkyEcho2 to the Phablet was no problem, also the Bose A20 via BT with the same device. I selected bearingless targets in SD and of course the SkyEcho as external device. At the first flight I was quite disappointed, all traffic could be seen on the screen (heli, glider and other VFR traffic, even airliner), but there was no aural alert in the headsets. I turned media level to the maximum in the Android device, still no alerts. After landing the problem was clear, the A20 has separate buttons for BT sound level, and that was at a minimum...On the second and following flights everything was perfect, aural alerts from SD regarding terrain etc. and traffic alerts! I had about 5 flight hours since then, and only once one single engine aircraft, which crossed my path 1000ft above, was not shown in SD (but possibly this aircraft had turned off it´s Mode C or S).
Conclusion: For me as a vintage aircraft user, with no electrical system on board, this combination is big step forward and makes flying much safer. On the other hand, pilots with installed FLARM or Mode S/C systems, e.g. a Garmin system, might have more advantages (see problematic Mode S/C indications in SD (bearingless targets) in other threads)).
Cheers,
A.
