RoboAlbert,
I'm fairly sure that the standard drop technique for CDS is 50 flap with a 7 degree deck angle. The beauty of the J is that 7 degrees can be nailed every time using HUD symbology. Early CDS trials, I am led to believe, have been fairly encouraging. Foot and Mouth and lack of money have brought it all to a grinding halt. Word of caution - don't be surprised if QQ manage to turn CDS (the worlds most successful and widely used air drop system) into good old fashioned AGE!!
Bring back ME and all is forgiven!
