- Lift produced by a body displacing a greater weight of air than its own weight is called _________ lift.
- Aerostatic
- Lift produced by the reaction caused when a mass of air is deflected downward is called __________ lift.
- Aerodynamic
- The lowest layer of our atmosphere is called the ________________.
- Troposphere
- The layer of our atmosphere that is typified by the temperature of the air remaining constant as the pressure continues to drop is called the _________.
- Stratosphere
- The type of altitude measurement used to determine the amount of lift produced by an airfoil or the performance of an aircraft engine is ______________ altitude.
- Density
- The principle of physics that states that if the total energy in the air moving over an airfoil remains constant, any increase in its velocity will result in a corresponding decrease in its pressure, is called _________ principle.
