They have managed to measure the weight of an Airbus A320 aircraft in the air from the ground.

A YouTuber has managed to accurately measure the weight of an Airbus A320 aircraft in flight using a setup he set up on the ground. This is a remarkable piece of work that creatively combines the laws of aviation and physics.

Engineer and YouTuber Brian Haidet showed how he measures the weight of an aircraft in flight on his YouTube channel AlphaPhoenix. Normally, the weight of an aircraft is determined by special scales placed under the landing gear. However, Haidet tried to overcome this challenge by using a more experimental and public approach instead of resorting to this traditional method. The basis of his experiment is the principle that a flying object rises by pushing air downwards, and that this pushing air eventually exerts a force on the ground.

Haidet developed a sensitive weighing system to detect this force. This system is based on load cells, which change their resistance when subjected to a load, thus allowing them to measure the weight. First, he tested the functionality of this homemade scale by dropping paper airplanes onto it, successfully recording the downward force created by the paper airplanes.

After these successful preliminary tests, he moved the experiment to an area where a real airplane was flying by. He made some adjustments to the weighing system for a full-scale airplane; instead of measuring the weight directly, he aimed to reach the result by comparing the pressure changes inside a box with the outside, and again using load cells.

The experiments are promising

The experimental conditions were far from ideal; windy weather and the lack of a giant scale that could measure the weight spread over a large area of ​​the airplane presented difficulties. However, after a few tries, Haidet was able to detect the signal created by an airplane passing over him. Although there were some "strange negative signals" in the data he obtained, he used the clearest and least negative-signaling measurements to make a rough estimate of the airplane's weight. With his assumptions (such as the airplane's speed and distance), the weight he obtained was around 2 tons. Although this is far below the actual weight of an Airbus A320, it was considered quite an impressive feat to be able to detect and even roughly measure the weight of an aircraft flying from the ground.

Although this technique may seem like a YouTube show for now, it is likely to be used in the future to develop new applications in different areas with more sensitive devices.
