I emailed uAvionix...
Two questions:
First, I noticed on the AML, all Mooney models are shown except the M20K. Is this intentional or simply an unintended omission/typo?
Second, can the AV-30-C be used as a standby/backup Attitude Indicator to my Aspen EFD 1000?
The response:
The FAA limited us in the certification and the M20K has some s/n that are rated above 25,000 ft. I doubt that you fly at those levels, but because the TCDS limits it there that is why it wasn't on the first AML. We hope to expand it to include the M20K in the future. The AV-30-C is a certified backup indicator, but it is dependant on the STC of the Aspen whether they would allow the AV-30-C to be used as a backup indicator. I am sure if you call them they might have an answer for you.
