Wind displayed with no IRS

[falcon71]

I noticed that the wind is shown on the ND on the ground with no available IRS:

The value is actually correct. This is unexpected though, since the wind is usually calculated comparing the GS with the TAS and the heading with the track. Thus I would have expected the wind data to be only available in the air and with the IRS available.

Thank you for the feedback. Looking into this, the wind speed is computed by the IRU so it shouldn't be visible prior to IRS alignment. I have logged this on our internal bug tracker to investigate for a future update.
