EFIS-D10A / EFIS-D100 Allowed as Backup Attitude Indicator
In addition to the updated AML, the STC’s instructions for continued airworthiness have been updated to clarify that the Dynon EFIS-D10A or EFIS-D100 may be used either as primary instrumentation or as a backup. This can allow pilots of aircraft where a specific primary attitude indicator is needed for other systems - such as autopilot - to still install a Dynon EFIS as a backup.For more information on this and other installation scenarios, see the full list of Frequently Asked Questions on the Dynon website.
