easyJet Unveils Ash Detector to End Large-Scale Disruption

easyJet, the UK’s largest airline, today unveils a ground breaking technology that will minimise future disruption from volcanic activity.

easyJet will be the world’s first airline to trial a new technology called AVOID (Airborne Volcanic Object Identifier and Detector). The system, essentially a weather radar for ash, was created by Dr Fred Prata of the Norwegian Institute for Air Research (NILU). AVOID is a system that involves placing infrared technology onto an aircraft to supply images to both the pilots and an airline’s flight control centre.

These images will enable pilots to see an ash cloud up to 100 km ahead of the aircraft and at altitudes between 5,000ft and 50,000ft. This will allow pilots to make adjustments to the plane’s flight path to avoid any ash cloud. The concept is very similar to weather radars which are standard on commercial airliners today.

On the ground, information from aircraft with AVOID technology would be used to build an accurate image of the volcanic ash cloud using real time data. This would open up large areas of airspace that would otherwise be closed during a volcanic eruption, which would benefit passengers by minimising disruption.

easyJet Chief Executive Andy Harrison, said: “This pioneering technology is the silver bullet that will make large-scale ash disruption history. The ash detector will enable our aircraft to see and avoid the ash cloud, just like airborne weather radars and weather maps make thunderstorms visible.”

Dr Fred Prata, Senior Scientist at the Norwegian Institute for Air Research (NILU) and inventor of the AVOID system added: “AVOID enhances the theory around volcanic ash clouds with live data. easyJet is committed to bring our technology to life.”

Commenting on today’s news Andrew Haines, Chief Executive of the Civil Aviation Authority said “It is essential that the aviation community works together to develop solutions to minimise disruption, should ash return. The CAA welcomes the fact that airlines are considering innovations such as this and we will do all we can to facilitate them.”

The first test flight is to be carried out by Airbus on behalf of easyJet within two months, using an Airbus 340 test aircraft. Subject to the results of these tests, easyJet intends to trial the technology on its own aircraft with a view to installing it on enough aircraft to minimise future disruption from ash.

easyJet is now Europe's No. 1 air transport network due to its leading presence on Europe’s top 100 routes and at Europe’s 50 largest airports. More than 300 million Europeans live within one hour’s drive of an easyJet airport, more than any other airline.

By offering the lowest fares to the most convenient airports, this year easyJet will grow profitably by 10% and will carry 50 million passengers on over 500 routes between 120 airports in 29 countries.

easyJet is the UK’s largest and Europe’s fourth largest airline by passenger numbers. In 2009, the airline carried 28 million passengers in the UK and 46 million in total. On average easyJet flies passengers 1100 km for just ₤45/€50.
easyJet takes sustainability seriously. Over the last 10 years, the airline has reduced CO2 emissions per passenger km by 25% by investing in the latest technology. Its fleet of nearly 200 state-of-the-art aircraft is only 3.5 years old.

Notes to Editors:

Dr Fred Prata background
Dr Fred Prata is Senior Scientist for the Norwegian Institute for Air Research (NILU). He is also Director of Narcarnica (a spin-off company of the Norwegian Institute for Air Research (NILU) A biography is available on request. Fred holds a PhD from Oxford University in stratospheric dynamics.

easyJet expects to spend around £1million in capital expenditure this year on the development phase and initial installation. We will then see how much it will cost to roll it out but we do not expect the cost to be material.
