Bsieker,
The warning display "ENG THRUST LOCKED" on the E/WD is inhibited on the ground, i. e. in all flight phases before liftoff, and all flight phases after touchdown.
I don't have the whole A320 FCOM (have 2, 3 and 4th volumes).
Do you know where the above reference exactly is in the FCOM ? Or is it really in a separated diagram like that one refering to the other warning now implemented by AI ?
