The noseup trim is set pre-launch based on aircraft configuration and load. With five flight computers (four in the AC plus the stupid pilot as the fifth), pilot input is "considered". In other words, you are voting member in control of the aircraft, but the aircraft can decide your input is not desired and ignore you. This is the case on a cat-shot. MIL power, wipe out the controls, select full AB (if fully loaded), and salute. Right hand grabs the "awww ****" or "towel rack handle" on the canopy rail, left hand locks out the throttle.
The nose up trim programs the aircraft attitude to optimize angle of attach with margin during the cat shot. If someone puts too much trim in, you see the nose come up quickly, too little and the shot is much flatter than expected. In either case, you are likely to have someone yammering over the radio to "help."
Once thrown of the front, one potato two, hand back to the stick, clearing turn day-time, gear up, flaps to follow, go about your business.
