Airports

There are airports in every country.

In theory, an aircraft can fly an infinite number of paths through the air from any surface point to any other. In practice, paths of flight lead from airport to airport. Aircraft not only need proper landing and take off facilities. Moreover, those who use aircraft need services and accommodations which the airport must provide.

In the interest of aviation safety and air traffic assistance and control air traffic rules were established. The rules relate chiefly to weather minima, flight altitudes and traffic patterns which are to be used under different circumstances.

The modern airport is a complex structure, a centre of most diversified services. Millions of passengers and thousands of tons of airfreight are handled by modern airports. Thousands of people are working at airports.

In practical any airport can be divided into two main parts: the landing area (runways and taxiways) and the terminal area (aprons, buildings, car parking areas, hangars, etc.). There is also a third part - terminal air traffic control. The landing area includes runways and taxiways. The number of runways, their length and location depend on the volume and character of traffic, the prevailing wind direction and other factors.

The runways and taxiways should be arranged so that to prevent delays on landing, taxying and take off operations.

Aprons are required for aircraft to make final checks prior to departure.

The main function of the terminal buildings is to handle the departing and arriving passengers and their baggage.

Among the airport services are: flight assistance service, air traffic control services - airport traffic control, approach control, air route traffic control, radio communications and weather observation and forecasting service.

At every airport there is a number of supplementary services such as rescue and security services, an airport clinic, a fire brigade, special vehicles and equipment units (water trucks, tow tractors, etc.).

Other services include maintenance, overhaul and repair of stationary and mobile equipment, the supply of electricity, water, heat and air conditioning.

The facilities include runways, air navigational aids, passenger and cargo terminals. The airport has a hotel, a post office, bank offices, restaurants, car rental firms, etc. In the terminal there is everything for quick passenger handling: check-in desks, electronic flight information board of departure and arrival times, the baggage claim carousel and many others.
