Air velocity correlation to aircraft location
When real time streaming of position and aircraft parameters becomes the norm over black box recording, there might be enough collective data to derive wind velocity maps. i.e. comparing GPS with working pitot static data in the majority of working planes travelling known routes. Apart from general meteo' data gathering uses, might that be useful for an aircraft with trouble to at least have a stab at estimating local wind from GPS as secondary / backup - or could there be a use for comparing the two sirspeed data sets if pitot dynamic (and possibly static) information is lost ?
