Snap roll: This is indeed the recipe for a snap roll: starting from a speed slightly above the stall, apply a sudden yaw with the rudder, apply opposite aileron, and pull back on the yoke. SNAP! --- One wing stalls and the plane rolls over.
[I liked the clever use of the word, "recipe" with the phrase "snap *roll*"] This would be hard to model using lookup tables, but it might be possible using JSBSim functions and a table or tables, together. Could be fun. I need to think about this one. The first idea that comes to mind is that if the aircraft speed minus the yaw rate times some characteristic lateral length (span/2?) falls below the stall speed, then a rolling moment would be generated - maybe a yawing moment, too.
