USair A320 engine data
Not sure if anyone posted this already but it's interesting.

It's been 9 months since I 'airbused', so any current a320 pilots out there, please chime in.
Regarding the RAT:
"The device provides power to one of three hydraulic systems onboard which would have given pilots the ability to deploy slats but not flaps."
The slats and flaps both work, however at half speed. (the RAT pumps the blue hydraulic system and that system's fluid powers the back-up electrical generator)
Regarding the Ditching Switch:
This crew, as any other crew would in a similar situation, did an outstanding job to steer clear of populated areas in the extremely short time they were airborne.

The article said the RAT was deployed, engine one had 35% N1 through touchdown, but without knowing the core RPM of N2 it would be hard to say if the IDG stayed online. 48% N2 for the IDG on the other motors. Need a CFM type to clarify that. What is certai n is The RAT was either manually deployed or AC busses 1&2 were unpowered at least momentarily triggering the auto deployment.
As for the ditching switch, with the way the situation continued to degrade in a short timespan, they did a great job of doing job number 1....Maintain Aircraft Control!!! The ditching switch would have been a nice catch but I think only done by memory since I doubt they had time to open the ditching checklist.
IMHO

This accident is a reminder that while we train to take our time and think everything through, most major catastrophes unfold rather quickly. Excellent job, ditching pushbutton, wouldn't have made much of a difference in the end anyways.
