Blinkz,
being as much precise as it gets, I am not talking about "ENG REVERSE UNLOCKED" which by the way is not inhibited in phase 4 (80kt to lift off) if engine thrust is automatically set to idle, and obviously is a reason to reject take off between 100kt and V1.
I am referring to "ENG REVERSER FAULT" (loss of thrust reverser on one engine due to systems components, sensors or FADEC fault). It would help if you (or anybody) had the time to look up the specific pages in the FCOM.
Thanks.
