Airline’s ash detector could put an end to future travel chaos

airlines ash detector could put an end to future travel chaos volcanoIn April 2010, a volcano with a name that few people can pronounce erupted in Iceland. Eyjafjallajökull spewed ash high into the atmosphere and across Europe, closing down airports on the continent and disrupting air travel around the world. An estimated 10 million passengers were left stranded for more than a week.

While aviation authorities across much of Europe insisted airports should remain closed until the ash cleared, the airlines, who were losing millions of dollars for every day they couldn’t fly, insisted the skies were, for the most part, safe.

As one of those stranded far from home, I was rather pleased the authorities were erring on the side of caution, which I found preferable to being faced with melted engines at 38,000 feet.

At some point, it’s going to happen all over again, with another Icelandic volcano, the easier-to-pronounce Katla, ready to blow. Alarmingly, scientists believe Katla, whose next eruption is overdue, will make Eyjafjallajökull’s effort look like little more than a wheezy cough. When it does happen, the airlines want to be prepared, and UK budget flyer easyJet thinks it has the answer.

The airline has been developing the Airborne Volcanic Object Imaging Detector (with the definitely-not-accidental acronym AVOID) which, as its name suggests, detects ash clouds.

Flying into it could result in an aircraft’s engines melting, so theoretically the pilots would be able to take avoiding action. Quite how an air traffic controller would feel about having to give rapid instructions to possibly lots of planes needing to take avoiding action all at the same time is of course another matter.

The data from the plane’s cameras could be matched with satellite images to produce a 3D view of the plume of ash. According to a Sky News report, the technology has already been tested with a light aircraft flying near Italy’s Mount Etna. Tests on larger planes will be taking place in the near future.

If the AVOID system had been in place during last year’s Icelandic eruption, easyJet’s head of engineering Ian Davies thinks things would’ve been very different. “Airspace would probably have been open for the vast majority of time, in other words we closed lots of airspace that we would not have had to, if we’d had this technology.”

However, Dr Colin Brown from the Institute of Mechanical Engineers struck a cautionary note, saying that AVOID doesn’t make aircraft ash-proof. “We shouldn’t be duped into thinking that this is a solution which allows everyone to fly. It’s a detection system, it doesn’t actually improve the safety of the aircraft.”

Would you be happy flying in an area close to where ash is floating about if your aircraft was using the AVOID system, or would you prefer to keep your feet firmly on the ground until the situation had blown over?
