A related question: is BTV supposed to slow the aircraft by the selected exit without the use of any reverse thrust?
Youre supposed to use it with btv basically what btv is its a normal autbrake but with a more advanced system. you select where you want to exit the runway the system then calculates based on the weight of the plane, configuration etc how much brake force it should apply. if you dont use reverse thrust the tire brake pads will have to compensate for that loss of deceleration meaning more wear and tear on the brake pads so just like in real life you should use reverse thrust when using btv
