Aircraft can come in many shapes and sizes, accommodating particular design requirements, applications, and needs. When observing various aircraft, you may have noticed that some airliners feature a lower tailplane while others may have what is known as a T-tail. While differing from a majority of designs found on commercial airliners, these T-tails serve a significant role in flight.

Jet engines are complex pieces of machinery that propel giant metal contraptions tens of thousands of feet in the air. They’re a type of combustion reaction engine that discharge fast-moving streams of fluid and generate thrust by propulsion. They’re made of different parts: a fan, compressor, combustor, turbine, nozzle, and exhaust.
