Oh c'mon Bloggs, it's not that hard, surely? "If we have an engine failure before the turn, then we'll continue straight ahead. After the turn we'll continue on the SID". I reckon most of us could cope with that. The FMS detects the engine failure and automatically brings up the EO SID. To continue straight ahead, the PM only needs to select 'insert' and check the active waypoint is correct.
Why would you wait until DER to decide which way to go? If the failure occurs before DER, the decision is already made. If the failure occurs at DER, then it would probably be safer to continue straight ahead anyway, because you'd be well past the turn point by the time you got over the initial 'oh ****' and got things sorted.
Besides, doesn't the airbii maintain whatever the PF has set, bank-wise, so if you slot one as you roll into the turn (the worst scenario) it won't go wobbly?
Nice theory, not so good in practice. It still gets the wobbles, especially if the pilot makes any aileron input.
