HS34 power supply

[bernhard]

Hi
Most GA aircraft have separate switches to power instruments and avionics. Would it be better to switch power for the HS34 together with the EFIS/EMS, in which case it is powered up with the avionics powerless or rather with the avionis, in which case the EFIS/EMS are already running when the HS 34 is powered up?

Cheers
Bernhard

We'd prefer to see the HS34 come on at the same time as the EFIS. If you don't do this, you may get a warning on the EFIS that the HS34 is not detected.

All Dynon Avionics products are protected against voltage spikes, so they can be on during engine crank.
