Bonjour KayPam.

On A320/A321/A330, the wind strength and direction is displayed on the ND from 100 kts on the take-off roll - I think that is IAS/TAS

Like the OP, I would be very interested to know how these older aircraft calculate the wind direction information while still on the runway, and why the wind vector information is displayed from 100 kts and not later.

Would it be possible to ask your Airbus colleagues?
