The existing optimized braking to vacate at a pre-selected runway exit is combined with an assistance to Flight Crew for an efficient turn-off until aircraft has left runway protected area on the runway exit. This results in a reduced and more predictable arrival ROT, coordinated with ground ATC through datalink, and based on avionics that controls the deceleration of the aircraft to the design speed and supports the Flight Crew in an efficient turn-off (fast, accurate and reliable) at the selected exit.
The benefits of this operational improvement (mainly the enhanced ROT predictability) will show both in good visibility conditions as well as in low visibility conditions (especially in AUTO-LAND mode in CAT IIIb & c). Indeed, the benefit is likely to be bigger in low visibility conditions where the observed arrival ROT is generally greater than the one observed in good visibility conditions.
