Concorde, if you ask an aviation fan who saw the Concorde flying live to tell you about the experience, be careful, as you will hear a love story. Even those who are not aviation fans know this name. The Concorde was one of the most fascinating engineering works the world has ever seen. But the question is, will we see another supersonic passenger aircraft, and will it work this time? Several supersonic commercial aircraft projects were considered, but only two came to fruition: the Soviet TU-144 and the Anglo-Frances Concorde; both aircraft could fly at more than 2000km/h. The Soviet model had a short life with several problems in its development, and two fatal accidents at the very beginning of its career ended the project prematurely. The Concorde had a slightly longer life, but its end also came. The End of Supersonics On November 23, 2003, the world witnessed the last flight of a supersonic commercial plane; the Concorde performed its last dance with the British flag over the s...

We are used to seeing the largest airports in Europe located in the capitals or most populous cities, in London we have Heathrow, 25km from the center of the country's capital, in Paris Charles de Gaulle 25km from the center of Paris, and in Germany the airport from Frankfurt to.... 551 km from the capital, Berlin. Well, it's easy to explain why airports like Heathrow (London), Charles de Gaulle (Paris), Fiumicino (Rome), and Istanbul Airport in Turkey are the main hubs in their countries. Both airports are located in each country's most populous cities, making them the leading choice for several airlines. But what about Frankfurt? In Germany, the choice of main hub is a little different from what is usual in Europe. Frankfurt am Main Airport, a unique and strategic choice, is located 15km from the center of Frankfurt, the fifth largest city in Germany. There are several intriguing explanations that can justify the choice of Frankfurt as the main hub in Germany. The city...

The numbers don't lie; aviation is exceptionally safe and the second safest mode of transport in the world after the elevator (yes, elevators are on that list). The incidence of accidents in the billions of miles traveled makes aviation almost infallible. But like any system, aviation still has flaws, but will we ever see aviation without failures, without accidents, without lives lost? 49 in 2010, 11 in 2018, and 7 in 2022 are not random numbers; they are the number of fatal aviation accidents, 7 accidents may seem small, but we lost 160 people in these accidents, people whose lives were abruptly interrupted. But what we can do to honor the lives of these people and not allow their deaths to be in vain is to try to find the reason for the accident and prevent it from happening again; this is the fundamental pillar of modern aviation, ICAO statistics show a constant reduction in fatal accidents in aviation, showing that we are on a good path. An accident-free future Imagining a ...

If you have ever traveled on an Airbus A320 aircraft, you must have heard a very peculiar sound before takeoff or after landing, a sound that is associated with a dog barking, and which seems to announce that something is wrong with the aircraft. Well, there's no need to be scared, if you hear that noise it means that the PTU is working. But what is PTU and how does it work? Well, PTU is the acronym for Power Transfer Unit, and this system is part of the aircraft's hydraulic system, but to understand how the PTU works, we need to understand how the Airbus A320's hydraulic system works. The Hydraulic System There are 3 hydraulic systems completely independent of each other inside an Airbus A320; each system is identified with a color; we have the Blue, Yellow, and Green systems. Each system is pressurized separately from the other. The Blue system uses an electrical pump to pressurize its system. The Green and Yellow systems, which are the most used systems on the aircraf...

We have created a machine that thrives where we cannot. We humans always look at the sky and aim to conquer it, but there is a problem. We were not made to live in the skies at high altitudes, and often, when we are on board an aircraft, our body likes to remind us of that. Who has never felt an earache or even a blocked ear and wondered why this happens even though the aircraft is pressurized? The pressure and pressurization of an aircraft The pressure at sea level is approximately 1 bar, but as you go up, it decreases; this is because the pressure is the force exerted by the air in relation to a surface, and the higher you go, the less atmosphere there is above you, i.e. less pressure (For comparison, at 8,840m or 29,000ft above sea level, on the summit of Mount Evarest, atmospheric pressure is approximately 0.3 Bar). Human beings evolved to live at sea level and just a little above it, not at 8000m high, so the solution was to create an "artificial pressure" inside the ...

The story of the Airbus A380 is a fascinating study of how an impressive technological innovation can address significant challenges in the complex world of commercial aviation. The A380, also nicknamed “Superjumbo,” was presented as a game changer in the aviation industry, promising to transport more passengers with greater comfort and efficiency over long distances. However, over the years, the A380 has also become a notorious example of how even the grandest visions can struggle in the global marketplace. The “SuperJumbo” project, initially named A3XX, was announced on December 19, 2000, Airbus presented this model to the world as the largest commercial passenger aircraft in the world. It had its first flight on April 27, 2005, which was and is considered by many to be one of the greatest achievements in the history of aviation. The A380 has a maximum take-off weight of 590,000kg, has 320,000 pounds of thrust in its 4 engines, is 73 meters long and has a wingspan of 79 meters (Comp...
