Do you want to use Manual Targeting? Many people here do, I simply have no skill for it and use Auto.
But just in case you think you have to use Manual, you don't. (The patches you download have an option that gives you no choice, uncheck that prior to a mission if you want to use Auto.)
And the stuff you are asking about will be done for you (as explained in the book/training exercises).
But if you want to do Manual, more power to you.
