What is V1, and what decision does it represent during takeoff?

V1 is the takeoff decision speed. It marks the point at which you must decide whether to abort the takeoff or continue with the takeoff. If an engine failure occurs before reaching V1, you can stop on the runway safely by applying brakes and thrust reverse as needed. If the failure happens at or after V1, there isn’t enough runway left to stop safely, so the takeoff must be continued. This speed isn't the rotation speed (the speed at which you start to lift the nose) and it's not stall speed in the takeoff configuration. Those speeds serve different purposes. V1 is determined from performance data to balance the ability to stop safely if needed with the ability to continue and climb if an engine fails.
