Throttle, pitch-over start altitude, and turn rate are tunable before and during flight — they change the trajectory.
Throttle back through max-Q: pushing 100% through extreme dynamic pressure can destroy the vehicle.

Two-stage orbital vehicle, fueled and venting. Tune the pitch program, then start the countdown. Different settings fly visibly different trajectories — a steep or shallow ascent, propellant starvation, or a clean orbit insertion.
