Describe the bug

With ADIRS not aligned, ALT blue is displayed in the FMA

Expected behavior

FD modes should only be engaged when ADIRS are aligned.
Tried to find this information in FCOM but unsucessful so far, so I'm using my experience.

Steps to reproduce

1. Load the plane in C/D
2. Apply power and check the FMA
