Hi!!! I would like to know how autobrake works after 737 touch. When the autobrake is actived and deactived by aircraft?Thanks!!!Richard Lemos

On approach to land, select A/B 1, 2, 3, or MAX. When you touchdown on the runway the brakes will apply and remain active until the acft comes to a complete stop (I think you can also just turn the knob to A/B 0 while still moving to remove brakes).On takeoff, select A/B RTO which stands for Rejected Take Off. In this scenario, when you reach a certain speed (80 KIAS?) and then you reduce throttles to zero, the brakes are automatically applied and perform as above.Phill
