People try to push the thrust levers all the way to takeoff thrust manually and disengage the auto throttles. This emergency AD is an awareness campaign. Operators will make their pilots aware of the possible issues. Training curriculum will incorporate these scenarios and instructors will make it a strong point of emphasis during training.
