AS the L2 doesn't have the flight envelope protection of the 225. I can't remember what, if anything, it does have in this respect, but I do know that when you use Altitude Aquire, it doesn't command the aircraft to climb or descend. So you have to arm Alt.A first, then use VS mode to actually initiate the climb or descent.
And to think, I used to think the L2 was quite good - then I flew the 225!
