Not being an Airbus guru, I'd have to ask which models are equipped with a side-slip vane? I know I've seen them on at least some models.
If so equipped wouldn't it be possible that measured side-slip angle could be incorporated into the wind triangle calculation?
Takeoff run:
ADC calculated TAS = 100 kts
GPS calculated GS = 80 kts
Weight on wheels = TRUE
Wheel speed sensors = 80 kts
Rwy HDG = 090 deg.
GPS calculated track = 090 deg. (drift angle = 0 deg.)
Side-slip sensor angle = 5 deg.
From the above provided data, can the direction and velocity of the wind be determined?
Of course it can.
Knowing the side-slip angle can also be used to apply pitot/static pressure corrections based on tables derived from flight test data.
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.
I'd like to see what an avionics tech familiar with these systems has to share regarding this capability.
