What is the role of the Autothrottle system during a normal takeoff on the 737?

Autothrottle’s job is to manage engine thrust to reach and hold the airplane at the commanded speed during takeoff and the subsequent climb when it’s engaged. On a normal 737 takeoff, once you arm the autothrottle (with TOGA thrust selected), the system automatically adjusts thrust to hit the takeoff speed targets and then maintain the proper climb speed as the aircraft accelerates and configurations change. This keeps the airspeed on the planned schedule even if wind or engine performance varies, allowing the crew to focus on flight path and navigation. It isn’t about braking, and it isn’t limited to cruise—it's active during takeoff and climb.
