rudderrudderrat,
You're absolutely correct. This is really a hypothetical situation that would never happen because after a lost engine, you'd return to the airport. Problem is, the people I'm talking to don't necessarily believe that. They think you should be able to continue the SID on single engine. Of course airplanes have run into cumulogranite with that mindset, which is why I'm trying to influence the change.
I'm trying to prove that they've been operating outside the safety margin, or more probably, they're not aware of exactly what their operations group is doing (it's not a group of pilots I need to convince, rather a group of execs).
Thanks all for your help. I'm certain enough that the Airbus can't maintain 5.8% single engine at FL100 to challenge them on it.
