I would like to ask about the wind estimation in PDA.
The screen 4 of the PDA shows a wind rose with an indicator of wind direction and strength.
I would like to know if this indication of the wind is the real wind -created in the simulated environment- or is the result of a computation of the PDA.
In the second case I suppose that the calculation is based on navigation data: GPS, IAS and compass. In this case, how can local parameters be used to calculate a global environment vale -like the wind-?
Apologize for a probable chilly question.
Thanks and best regards.
Lorenzo.
