Nice system but I have had multiple failures. Problems personally involved in include
1. Pitot blocked=system shut down (yeap everything - computer says does not compute and shuts down!)
2. AHRS fail = lost A/H and HSI/DG (and at a bad time!)
3. AHRS fail (different aircraft, same result)
4. AHRS fail (same aircraft as incident 2 but after unit replaced).
Something on ATSB involving ASPEN unit as well..
Make sure that back up A/H (mandatory equipment) is working!
