Hi Simon, sorry you’re not correct.
From FCOM DISC-27-10-20 “Speedbrake extension is inhibited, if one of the following occurs:
- SEC1and SEC3 both are faulty, or
- An elevator (L or R) is faulty, or
- Angle-of-attack protection is faulty, or
- Flaps are in configuration FULL, or
- Thrust levers are above MCT position, or
- Alpha Floor is activated.”
Cheers.
