You just descibed CT jump travel. The navigator can make themselves useful by carrying the cassettes, installing and uninstalling them, pressing the big red button, and making coffee whenever asked.These aren't the droids you are looking for..?
If it is all safe and easy why even have skills that apply to it. Just say the ships computer does all that and have done.
I houseruled navigators plotting jumps and maintaining a jump rutter years ago.
