Analog #1 and #2 is pure backup, with reduced handling qualities, more or less no decoupling and no upper modes.

The four lanes isnt connected to a specific computer but is handled by a actuator control computer (two
ACC’s actually) that selects what signals to send to the actuators.

= NH90 have digital FBW with analog backup.

Analog FBW computers as main FBW Computers should be a long time since put in
Aircrafts.
Im sure all three mentioned have digital FBW.
