A310driver - forgive me if I am wrong but you appear to suggest that Airbus should have 'idiot proofed' their design. It's rather difficult to do that, and just as it is postulated that a million monkeys with typewriters, given infiinite time, will type the works of Shakespeare, so will a large number of pilots, given sufficient time, find a hole in any system design. Personally I am still wondering why on earth they could land with one engined in rev idle and the other in the climb gate. It so utterly defies logic to anyone who understands the 'bus that in could only be considered an unintentional error. As an aside it is perfectly feasible to land a 744 with three engines in idle and and one thrust lever advanced. How that affects the reverse/autobrake situation I haven't had time to investigate.
