So does Airbus incorporate this calculation capability to display actual wind direction and velocity on the PFD during takeoff? It doesn't seem all that daunting a task given the availability of sufficient data processing capability.
Why would airbus use anything complicated to calculate drift etc. when the use of wind display is not meant for the take off run? I don't know how many pilots look at ND during take off run. It is straight calculation airspeed-GS and once airborne it works by including HDG/TRK difference.
