No doubt we have heard or followed the news of an emergency landing. The last one with media repercussions occurred in Madrid in February 2020, when an Air Canada Boeing 767 declared an emergency shortly after take-off. The plane spent up to six hours orbiting the Madrid sky before landing back at Barajas airport. The main reason for this manoeuvre was to get rid of several tonnes of fuel, the weight of which would have made landing impossible.
Supersonic planes and the sound barrier
During World War II, the world of aviation underwent an impressive technological revolution. Each time the aircraft were able to fly higher and faster. But pilots and engineers ran into the so-called ‘sound barrier’ over and over again. That is, the possibility of exceeding the speed at which sonic waves are transmitted through the air. Approximately 344 m / s at 20 ° C temperature, or what is the same, 1,238.4 km / h.
What is the autopilot?
For students, future pilots, and even passengers with a certain concern to expand their knowledge, the automatic pilot of aircraft is not completely unknown. However, it is common to ask questions about its operation and role during the flight.
Withdrawal of four-engine aircraft
In recent months, we have seen how airlines such as Iberia, British Airways, or Qantas are withdrawing their four-engine A340 / 600 aircraft. At the same time, Boeing announced by 2022 the end of the manufacture of the B747. A legendary four-engine.
The trends of the aviation for 2021
At the last years, the industry of the aviation has suffered an extraordinary renewal: they have removed ancient aircraft substituting them for others more efficient, has increased the number of units of the fleets, deleting paths little profitable and improving the operative that offers at the customer. Everything this has permitted abaratir the cost of the tickets and pose near at hand of any one the possibility to travel with airliner.
Do you know what the Winglets are?
The winglets of an airplane are the fins, they are usually vertical, and are located at the tip of the wing. These make it possible to reduce the induced resistance. In other words, they serve to prevent the air flow from the soffit from mixing with that from the extrados due to the difference in pressure between them.
How are contrails left by airplanes generated and affected?
What are airplane contrails?
The white trails that aircraft sometimes leave in their wake are produced as a consequence of the high temperature of the gas jets that come out of the engines (often at temperatures above 500º C) in contrast to the low temperatures – of the order of minus 56ºC – which prevail at the heights at which commercial flights normally take place, which causes condensation and subsequent freezing of the water vapor they contain. These condensation trails – popularly known as “contrails”, a word derived from the English “condensation trails” – can turn into clouds, depending on the prevailing humidity, temperature and wind conditions at all times.
Super Guppy: The plane that transports spaceships
Large aircraft such as the Antonov 124, the Airbus Beluga, or the Super Guppy are always in the spotlight due to their large wingspan and their ability to carry extremely large loads, such as parts of other aircraft, components of spaceships, or even other whole planes.
The aircraft fuels of the future
Respect for the environment and the implementation of cleaner engines and fuels have occupied and concerned the aeronautical sector for decades.
Aircraft that have reached records
Since the beginnings of aviation, there have been many aircraft that have gone down in history, be it for their size, capabilities or broken records. We present the most outstanding ones.
