Im going to install an Avmap Ultra EFIS but notice it is not "certified."
As it is going in where the current ASI (80mm) is, I'm going to have put a small ASI (57mm) in a spare cutout.
What I'm wondering is:
- Does the ASI have to be TSO or certified (in other words do I have to bother putting in a smaller standby ASI at all?)
- If I do have to have a certified ASI as a backup to the EFIS can I install he smaller one myself and still be legal?
I have just got my first Savannah and I'm new to the sports category do's and don'ts.
any advice appreciated.
