We got our plane, SR20 s/n 1106, N747TG back out of the second anual inspection. Total time now is 370 hrs. 2 new tires, new brake linings and a new battery (on warranty), everything else pretty normal.
We got the first European Skywatch Retrofit Kit, the first European ARNAV BH upgrade, and (guess) the first European Improved Starting Kit. (We got the first European Engine Monitoring earlier this year - N747TG is the local guinea pig around here…)
Starting Kit: Fantastic! After 2 seconds prime, the engine starts immediately and runs smoothly. 2 years of starting problems finally came to an end. On the first re-start after refueling, I flooded the engine (my fault) - I’m careful now. But this is one of the best improvements you can add to your SR20.
Skywatch: There is not much to add to the many posts already posted. It is absolutely amazing how many airplanes are so close to you which you never see without such a system. Since Europe is way behind with Mode S, and since we have lots of fields with no Radar coverage where Mode S would not help anyway, this is the right solution for me. It works fantastic.
ARNAV: The improvement with BH has already been described by others. In DC-0, the refresh rates are still too slow. DC-1 has all you need, and refresh rates are acceptable. European air spaces and mountaineous areas are very well modelled, a big improement compared to the olden times. (Funny: We got the system installed in the Netherlands, with airport elevation at minus 11 feet - below sea level. Obviously, we were the first ever to try the BH software in the negative - we got a big “ERROR CODE”. However, ARNAV solved the software issue within 2 days!) With the BH software including Engine Monitoring, and now prepared for the ARINC 429 interface, I do not see any disadvantage compared to the Avidyne screen.
Big cudos to our Service Center, General Enterprises, who carefully solved all issues - first time jobs for them as well.
