AINsight: Explaining the Unexplainable Pilot ‘Action Slips’
Cognitive error during an automatic/routine task can turn deadly for aircraft crews

On June 28, 2024, the first officer of a Boeing 777-200 unexpectedly responded to an automated V1 callout by retarding the thrust levers instead of moving his hands to the control column. He then briefly advanced the thrust levers before finally rejecting the takeoff.

Under normal conditions, V1 is the maximum speed during takeoff at which a pilot must initiate the first action to safely abort the takeoff within the accelerate-stop distance. After this point in the takeoff roll, the pilot is committed to flying.
