Why Planes Can'tMove in Reverse? The reason will surprise you
Have you ever wondered if the planes are mirrored? Maybe not, but the answer may surprise you. Although they can't flip when flying because they will lose their payload - many planes can reverse the direction of their engines on the ground to push them back but it is not allowed to do so, why?
This maneuver is known as the "reverse direction" and consists of turning the reactor outlet so that the exhaust gases are ejected forward rather than backward. Pilots use the opposite direction when they need to brake quickly when landing, either because the landing distance is too short or because bad weather has reduced the efficiency of the brakes.
However, they rarely use the opposite direction to reverse. When the plane is ready to move from the boarding gate to the aisle, it does not do so by its own means as it does not turn back on its own, but via an additional vehicle called a tow tractor that pulls it back. This process is known as "push back".
Why can't the planes go back alone? There are a few reasons you might find strange, starting with the noise. Going backwards creates deafening noise, so it is avoided near stations and even on runway at night. But the motor voltage not only generates noise, but also large drafts that lift dirt off the ground. If there are metal objects in these explosions, they can injure the ground personnel and others, break the terminal windows, or damage the fuselage.
Other compelling reasons for not using the reverse direction are fuel consumption (acceleration in the opposite direction consumes more than usual, which means increased expenses for airlines) and increased pollution (maneuvering produces a lot of carbon dioxide, the main greenhouse gas). In addition, the brakes may cause the plane's tail to be injured, which any airline wants to avoid.
