SysML is an extension to UML to try and accomodate systems. AADL is a 
textual language, intended right from the start for system design. A 
feature-by- feature comparison would be too long for this thread...

This is a good question that should be directed to the SysML people. 
AADL evolved from MetaH, which was in use in avionics systems long 
before the SysML effort started. AADL is a registered standard *today*, 
while SysML is still in the early phases.

There is also a UML profile that will achieve standardization soon. We 
would have loved to have the OMG people participate, rather than 
starting their own effort from scratch.

I industry makes technical decisions based on the selling price of a 
standard... then I'm afraid of the future of industry!

Moreover, free availability of the standard is not the most important 
thing. AADL *today* has a free Eclipse plug-in (OSATE), emacs mode, free 
tutorials, etc. See http://www.aadl.info.
