Not sure I see what you mean, Don. If you are handling the weapons as CPG then George will have to fly surely? Having said that, you could take control of the aircraft away from George as CPG and ignore what the instructor says, but I think it's a useful lesson for learning a few basic George commands as well.
In the TM, you get a chance to use the weapons with the CPG and then, after you've completed that, you do it as the pilot and in that part, you are doing the flying.
