Commercial Transport Planes
Commercial transport planes, or commercial planes as they are commonly known, can either be used for passengers or cargo. The size of these planes is generally larger than the other types of planes. Some of these planes are also known as airliners.
All the modern commercial transport planes use jet engines which allow them to fly at a speed as high as 500-600 miles per hour. These planes generally have a minimum of four jet engines, however, there are planes which have as many as eight. Commercial transport planes are supposed to be among the fastest type of airplanes. They have the basic structure of an airplane, comprising of a fuselage and two large wings fixed with the required jet engines. The jet engines themselves are also used in military aircraft.
A famous example of a commercial passenger plane is Boeing 747, a four jet plane. This plane can carry as many as 1000 passengers at a time and has a fuel-carrying capacity of 47,000 gallons, which allows it to fly for a prolonged period of time.
A Boeing 747 plane has the distinction of being the first large capacity modern commercial passenger plane constructed. Moreover, it also contains all high-class facilities required for the passengers’ comfort. Some of the features of this airplane include six galleys, twelve washrooms, and four bars and lounges.
Apart from four-jet airplanes, there are also three-jet and two-jet planes. These planes have a smaller passenger-carrying capacity and cannot travel for long durations as compared to their four-jet counterparts. However, twin-jet planes are the most reliable and widely used planes in the world.
Commercial transport planes are generally named using the company's name and model number. Each is also issued a serial number to tell the aircraft apart. Some, however, are simply one-off designs such as the Aérospatiale-BAC Concorde.
