Air Time,
I can't speak for the other varients, but the J gives the pilots AMAZING SA. Between the Nav Radar display, CAPS, DIG Map and the HUD, there are plenty of toys to keep you in the loop. There are tools to help you locate your position in relation to the DZ, LZs, formation positioning, draw avoidance areas over the white line that is your route, and ways to alter your route with accurate time calculations. Lets just say, every day I find something else to love about my plane.
