From the CGH crash thread on R&N it appears that it is possible, on the AB320 anyway, to select TOGA on one engine with a reverser selected open on the other. (NB No suggestion this was the cause!).
I am trying to think of the advantage of this facility and whether it should be blocked? It appears to have certainly caused one accident as per http://www.ntsb.gov/ntsb/brief.asp?ev_id=20020913X01603&key=1
I quote from that:
In an effort at maintaining directional control, the captain then moved the #1 thrust lever out of reverse and inadvertently moved it to the Take-Off/Go-Around (TOGA) position, while leaving the #2 thrust lever in the full reverse position. The thrust asymmetry created by the left engine at TOGA power with the right engine in full reverse greatly increased the right yaw forces, and they were not adequately compensated for by the crew's application of rudder and brake inputs.
Any comments?
