If FLAPS jammed at 0
SELECT CLEAN CONFIGURATION
I think the question he asked if flaps were to be jammed to more than 0 after take off.
What does your QRH say?
Boeing systems allow flaps retraction/extention using an electical motor following loss of hydraulics.
The loss of hydraulics could be the failure that causes his flaps to remain down after take off.
However if the flaps are 'jammed',ie were locked into their position due to assymetry,no retraction or extension is possible in boeing aircraft.
