The Flight Management system calculates the V approach and V lowest selected airspeeds for landing, but does not calculate the takeoff speeds.
Thanks. In light of recent events, has Airbus indicated any intention of implementing this functionality?
In the Virgin incident, the crew calculated the takeoff speeds using the expected landing weight. Had the FMC calculated the takeoff speeds, the crew would probably have caught the error when their speeds were significantly lower than the FMC speeds.
