Why is an air-cooled engine not used in an airplane?

There are some air cooled engines used in airplanes, Porsche's 911 engine has been used and is air-cooled. There is a Horsepower limit for an air cooled engine, so if you need to produce more Hp or have a bigger plane which needs more Hp then you need to switch to a water cooled design. The new Porsche 911 is a water cooled design because the Hp limit for a an air-cooled 3.6 liter engine was maxed out.
