How “Brake to Vacate“ Works on Airbus A380 & A350...to clarify; AUTOBRAKE is applied & MODULATED via BTV - to achieve the required speed at the desired exit...
Why use it? Lower brake temperatures, less brake wear, increased passenger comfort & faster turnarounds (less time waiting for brakes to cool). It saves time & money.
Helps result in lower runway occupancy times, because exit at correct speed & desired rwy exit point is more assured.
After runway & desired exit are selected by the pilot during cruise, velocity data from within the aircraft's GPS/IRS is used after touchdown to monitor the required deceleration, modulating AUTOBRAKE automatically to achieve the exit at the desired speed.
Can be disconnect by; use of manual brakes, speedbrake disarmed, or button on thrust levers. All feel natural.
Becomes second nature to the crew, and they can revert to regular autobrake or manual braking at any time.
I'm from background; Canadian Arctic bush pilot (wheels, skis, floats), RCAF jet & transport, Lockheed, Boeing & Airbus A320/A330/A340/A380 - I love/respect BTV.
