Aircraft - Impact and Use

Impact and Use

In general, aircraft have positive properties as they permit long distance, high speed travel and are often reasonably efficient. In addition to their usefulness, they have some environmental impacts. They generate some atmospheric pollution, are relatively noisy compared to other forms of travel and high altitude aircraft generate contrails which experimental evidence suggests may alter weather patterns.

Aircraft are produced in several different types optimized for various uses; military aircraft, which includes not just combat types but many types of supporting aircraft, and civil aircraft, which include all non-military types, experimental and model.
