 Airports generally have long , fully lit , hard @-@ surfaced runways , full air traffic control , and navigation and landing aids . They are usually located on urban fringes , support commercial and business operations , and often exclude certain types of light aircraft . At the more rurally located airfields , the lighter end of aviation , such as microlight and gliding activities , becomes increasingly prevalent , and there are few or no commercial operations other than flying schools . At this level runways are generally shorter , and grass surfaces are increasingly common . Navigation aids are increasingly scarce , being more basic where they are available , and informal ground to air radio communication replaces air traffic control . The smallest airfields are too small to feature on general purpose Ordnance Survey ( OS ) maps , and lack basic facilities such as fuel and maintenance . The majority of airstrips are basically single short grass runways with no supporting facilities , although the presence of a hangar is not uncommon at the larger examples . They do not feature on OS maps , and are owned by private clubs or , more commonly , individuals .
