Can someone me explain how to get in the so called >alternate< or >direct< law in air ??
They're not "so called", this is official Airbus terminology. FCOM 1.27.30 has it very neatly explained.
So, has the Airbus really changed FBW arhitecture on latest A320s from FAC/ELAC/SEC to PRIM/SEC, or what we have here is the charge of the MSFS brigade?
