Much has been written about this small device that all commercial aircraft have been incorporating for more than half a century. And little wonder: "black box" flight recorders are essential in order to identify the causes of an accident.

We know, thanks to ironclad statistics, that the airplane is the safest means of transportation, but several decades ago there was a model of aircraft, the Comet, whose accident rate was well outside of normal range. It was the earl

The Basics of Commercial Aircraft Safety

by Jorge de Luis Sierra

 

In recent times we've seen a flood of news related to air transport safety, especially in regards protective actions against the spread of COVID: terms like HEPA filters and other sanitary measurements in cabin such as ultraviolet lighting radiation or the use of products that neutralise the coronavirus - hydroalcoholic gels or other disinfectants -, have now become familiar to everyone.Considering the health and hygiene on board we can find some materials with antibac

Airline flights in much of the world are organised through a system called "hub-and-spoke," invented by U.S. airline Delta in 1955; made widespread in the USA after that country's deregulation of the airline industry in 1978; and commonplace in Europe as well since the European Union finally eliminated the last of its own air-industry restrictions in 1997. The model is named after the basic design of a traditional wheel, where the "hub" is a central airport and the spokes are the flights comin

In today’s commercial passenger aviation, understandably it’s the aircraft that get top billing and most of the attention. But the airport systems that make their operation possible include a complex array of equipment, much of which is unglamorous and goes largely unnoticed by the flying public. And one of the key contraptions along these lines is a low-slung vehicle called a pushback tug or tractor.

As the name implies, this doughty workhorse of the tarmac goes into action when it’s time to

A Question for Avgeeks: What Are 'Winglets?'

9837192256?profile=RESIZE_710x

 

At some point when you're approaching your plane you've surely wondered to yourself why the wings are curved, no? This design feature is called a winglet (also known as a wingtip device), and it's there not just to look cool but for an important purpose: to maximise aerodynamic efficiency. Interested in learning more? Read on!

If you're an aviation geek, you know that airplanes stay in the air thanks to the interaction of four types of physical phenomena:


Thrust - that related to the tractio

Even with all the signs and signals on the roads and motorways, all of us have at one time or another gotten lost whilst driving. It would be natural to imagine, therefore, that in the vast expanse of the sky it would be quite easy to get lost without any signals for guidance. However, the fact is that there are indeed signals up there to rely upon.

Going back to the early days of aviation, it’s true that the intrepid pilots of the day did have to rely upon navigation by sigh

Airport Marshallers: Traffic Cops of the Tarmac

se%C3%B1aleros.jpg?width=614


Today we hit the tarmac to learn more about the important role played by the ladies and gents you see outside your aircraft window gesticulating up a storm. They’re called marshallers(known as señaleros in Spanish), and besides guiding planes whilst they’re on the ground, these individuals perform other less well known functions as well, such as cooperating with other airport authorities to monitor various vital technical procedures, and providing assistance in case of an unusual incident of an

Landing Jetliners in Crosswinds



by José Miguel Rodriguez

Not long ago, this video went viral on YouTube, racking up more than 10 million views. Apart from the fact that the 1,200-millimetre telephoto lens thoroughly flattens both the foreground and background, making the airplanes seem suspended in midair, what on earth are these pilots up to? Specifically, what’s up with the bizarre landing technique

Believe it or not this technique is standard, by-the-book practice when there are strong lateral winds present during landing

The answer is, quite simply, yes. There’s a direct correlation between the type and number of coats of paint covering an aircraft and both its weight and aerodynamics — and therefore, of course, its fuel consumption. This, in turn, has an impact on the amount of carbon dioxide released into the atmosphere.

Airplane-paint-1.png?width=250Iberia is one of the first airlines in the world to utilise a new system of paint application which allows savings of some 30 percent in materials — not to mention time, as it requires only a s

The Skinny on Aircraft Evacuation Slides

by VaDeAviones.com


If you fly with any frequency, a phrase heard over the public address system, “crew, slide arm and cross check” is likely to ring a bell.  That “slide arm” refers to activation for potential use of the inflatable evacuation slide required on all aircraft where the floor is at least 1.8 metres (6 feet) above ground level. These slides are manufactured of various approved forms of resistant plastic, similar in consistency to rubber, reinforced with various layers to minimise th

Airline Maintenance Secrets Revealed

by Javier Pedreira


That 
air travel is the safest form of transportation going is not mere happenstance but rather due to rigourous maintenance of equipment and exhaustive training of personnel.

Although in 2010 Iberia added a major maintenance hangar at Barcelona airport, since the 1970s the primary maintenance facilities have been headquartered adjacent to Barajas Airport in a suburban Madrid industrial zone called La Muñoza. This 220,000-square metre (54-acre) is where aircraft engines con

What Planespotting Is All About

by Jorge Guardia/VaDeAviones

Spectacular aircraft photos abound all over the Web these days–shots taken on runways, in hangars, taking off/landing, at cruising altitude. And many of us who glance at them, sometimes think, “how cool,” and move on.

And then… there are the planespotters, along with their closely related–and sometimes overlapping–cousins, aviation geeks (aka “avgeeks”). These gloriously obsessed souls are a dedicated breed in love with aviation and airlines, follow industry news an
