One of the first things that is likely to be noticed during a visit to the local airport is thewide variety of airplane styles and designs. No matter what each looks like like they alldepend on the the same four factors which are lift, weight, thrust, and drag Lift is the upward force created by the effect of airflow as it passes over and u ...

... of the airplane. Lift is the key aerodynamic force. It is the force that opposes weight. In straight-and-level, unaccelerated flight, when weight and lift are equal, an airplane is in a state of equilibrium. If the other aerodynamic factors remain constant, that airplane neither gains nor loses altitude. When an airplane is stationary on the ramp, it is also in equilibrium, but the aerodynamic forces are not a factor. In calm wind conditions, the atmosphere exerts equal pressure on the upper and ...
