Hi vilas
Thanks for your reply.
Two reasons I gave I cannot give you a reference for, sorry. But let’s say that it is pretty reliable.
Indeed, only G+B SYS LO
PR mandates A/THR OFF due to reduced pitch authority to counteract pitch-power couple.
A/THR off for Direct Law is recommended though as per L2 note in FCOM-PRO-ABN-F/CTL-DIRECT LAW.
Well aware of GSmini not being related to A/THR.
