The flow of air which moves opposite the flight path of an airplane.


Relative wind.


Sailplane cadets use at Air Force Academy


Schweizer TG-4


Disrupts airflow over upper camber of the wing.


Divebrakes or spoilers


Average rate at which temperature decreases with an increase in altitude.


Lapse rate


The art of staying aloft by exploiting the energy of the atmosphere.


Soaring


A column of air that moves upward.


Thermal
