I love flying!
I apologize for a rookie question, but an answer from someone here may save me hours of searching and research!
Background: I am building an RV-12. The original kit version avionics had a D-180, an AP-74, and an optional D-100. With everything else in the plane, the rather current-limited Rotax 912ULS could handle this load, and the plane was approved with this option combo.
Now Van's offers the Skyview, but in an installation with only one 10-inch screen. Apparently after trying with 2 10-inch screens, they decided that the power budget was too close and that it might not be a poipular option, so a second SV screen is not being offerred directly by them.
(Note - after you build the kit and certify it as an E-LSA, you can then do any mod that you want. Also note that some have built the RV-12 as E-AB, not E-LSA, and are running dual 10 inch Skyview with no apparent problem.)
My specific questions have to do with eventually adding a secondary 7 inch SV screen:
1. What is the power consumption difference between a 7" SV unit and a 10 inch?
2. What is the power consumption difference for these two comparisons:
2a: a 10 inch SV and a 7 inch SV, single ADHRS
2b: one single D-180, AP-74, and D-100?
Assume no backup battery or charger, I can add that in separately.
Any response with links would be appreciated! I have done a minimal amount of searching on the site for electrical load specs and comparisons and come up empty. DItto for inside the Skyview installation guide.
THANKS!
