The airbus A350's pilots will have, as standard, an advanced landing safety function that will warn the pilots, during approach, of the risk of runway overrun. This is the most common type of airline accident. It is occasionally fatal, but almost always damaging to the aircraft.rnThe runway overrun protection system (ROPS) has been developed from the A380's "brake-to-vacate" (BTV) capability, says experimental test pilot Peter Chandler, whereas BTV itself will be optional on the A350. BTV is a programmable braking control system which, if set before landing, provides automatic braking to stow the aircraft evenly to enable the crew to turn off the runway at a chosen exit, potentially reducing runway occupancy time. BTV would be particularly useful when landing in marginal visibility.
