An airliner is a type of aircraft that transports passengers and cargo. Its wings have ailerons that raise and lower to control the roll of the airplane, and a rudder that controls the direction it yaws.

Airliners come in many different types, depending on size and power. These include narrow-body and wide-body aircraft. They also vary in how they are marketed and where they are used.


An airliner is an aircraft that is used to transport passengers and cargo. While the definition of an airliner can vary from country to country, it typically refers to a large airplane designed for commercial use by airlines.

Airliners fall into two categories: wide-body jets and smaller, lighter-than-air types. The larger ones, also called twin-aisle, are usually used for long-haul flights between airline hubs and major cities with many passengers.

In addition to being larger, wide-body aircraft have more advanced features like high-bypass turbofan engines that produce a more efficient flow of air than their smaller counterparts. Other features include a separate cabin for the crew, lavatories, stand-up cabins, pressurization, overhead storage bins, and reclining seats for comfort.

The narrow-body airliner category includes shorter and medium-distance aircraft that seat fewer than 100 passengers and may be powered by anything from turbofans to turboprops. These airliners are often called regional aircraft and are the non-mainline counterparts to the larger aircraft operated by major carriers, legacy carriers, and flag carriers.


An airliner’s seating arrangement is crucial to a good flight experience. You’ll want to choose a seat that offers you the best legroom and comfort for your particular needs.

Seats on widebody aircraft tend to be located in the middle of the plane, while narrowbody jets typically have seats along each side of the cabin. You’ll also need to consider where your seat is positioned on the aircraft, especially if you’re tall or overweight.

Many airlines assign a letter to each seat, so you can easily find your assigned seats without getting confused with row and seat numbers. This alphanumeric system is much easier to navigate than a number-based system, and helps avoid mishaps such as seats that end up in the wrong row.

You can also use websites that specialize in different types of airplanes to find out exactly where your aircraft’s seats are located. These sites will tell you about seat pitch and width, as well as where power ports and personal TV screens are located.


When an airliner is in the air, its jet engines not only generate thrust but also act as electrical power plants to supply power to all critical and auxiliary systems during flight. These systems include all control and navigational instruments, cabin lighting system, electrical motor driven mechanisms, cockpit or onboard kitchen appliances, passenger address (PA) or announcement system and entertainment systems such as display screens and mobile or laptop chargers.

The electrical power in an airliner is generated by engines using hot, fast-moving air created from the ignition of jet fuel to drive turbine blades in the rear of the engine. The spinning of these blades also turns a central shaft connected to an electrical generator.

A generator creates direct current electricity by turning magnets around wire coils. This energy is then delivered to an AC “bus” where aircraft electrical systems can source their power – much like a multiplug extension cord in our homes.


An airliner may seem like a scary thing to fly, but in reality they are one of the safest modes of transportation. According to the International Civil Aviation Organization, the rate of airplane accidents is down more than ten times from the 1950s and 1960s.

The aircraft industry is constantly working to make air travel safer for passengers and pilots. This includes improving safety equipment and technology as well as training.

Another way airlines are trying to keep passengers safe is by increasing the number of security checks on flights. These checks are designed to protect the plane from terrorists.

Other safety improvements include a system that keeps passengers in their seats and a fire emergency escape path marking system that will illuminate the floor of the cabin so that if smoke rises, it won’t be difficult for passengers to locate exit doors. Many of these features are hidden in plain sight and may seem small, but they are all part of an effort to make air travel safer.
