In addition to all the standard SR22 avionics, N882CD has upgraded avionics.
While we were considering upgrading the dual GNS 430 WAAS, we added a Flight Stream 210 that allows easy flight plan transfers from foreflight. This was so great it negated the need to upgrade. You can set up a flight plan at home and have it fully loaded in under 10 seconds, no matter how complex.
The Aspen Evolution 2000 Pro Max features magnetometer driven attitude indicators. Backing them up are analog instruments with a electrically driven vacuum pump that reduces the risk of a vacuum failure.
All this creates a triple instrument redundancy.
In addition the trusty STEC 55x was upgraded to a rock solid, fully digital autopilot: the Avidyne DFC90 with "Straight and Level" emergency recovery.
