Windsight

Windsight is an ability of the Aarakocra and certain air spirits. While useless below [layer], windsight is incredibly useful in the infinite sky, as it allows creatures to see the flow of the winds. The range of windsight is measured in kilometres.
When piloting flying vehicles, those with windsight receive a +4 bonus and may substitue their INT or WIS for DEX when making reflex saves while piloting. Windsight may or may not be connected to time somehow, seeing where the air will be in the future (future wind currents?).
The Kubu simulate windsight using enchanted monocles and some Gnomes have also found technological equivalents.
