[edit] Design and development

The IL-18 is a passenger airplane equipped with four turboprop engines. The airplane was mass manufactured for twelve years. A great popularity of the airplane was not ensured just because of its high reliability and operational economy, but because of the possibility to increase the number of passenger seats and its flight range for every next modification (A, B, V, D and E) as well. Besides the IL-18 was produced in VIP version («Salon»).

[edit] Operational history

Seventeen foreign air carriers acquired 125 IL-18 airplanes.During the 1958-1960 period, 25 world records were set up by these airplanes and among them flight range and altitude records were achieved with various payload capacities. In 1958 for its advantages the airplane was awarded the Brussels World Fair Grand Prix. In April 1979 in order to commemorate the merits of this remarkable airplane a monument was unveiled at the Sheremetevo airport, and it was dedicated to the airplane that operates at the Russian and international routes till now. The first IL-18 equipped with the NK-4 turboprop engines took off on July 4, 1957. On 17 September, 1958 the airplane took off with the new AI-20 engines. V. K. Kokkinaki was an airplane test pilot.

Seating 100 to 120 passengers, its operating economics are such that many are still in service in Cuba, Siberia and by some operators in the Middle East.

[edit] Price

According to Country Studies, Ghana purchased 8 Il-18's on credit in 1961, at a price of more than 1,500 000 $ each. However, since the operating costs were rather high, 4 were later returned to the USSR, and 4 others were used by Ghana airways.
