Flight operations to, from and within Europe are gradually being restored due to a combination of better fortune on the eruption/weather front and an increasingly pragmatic approach by regulators and manufacturers, while maintaining safety as the overriding priority. The UK Civil Aviation Authority (CAA), in conjunction with the Irish Aviation Authority (IAA) has issued new guidance on the use of airspace, covering the Anglo Irish Functional Airspace Block (FAB).
The new guidance allowed a phased reintroduction from 22:00 last night of much of the airspace that was closed due to the volcanic ash plume over the UK. There will continue to be some ‘no fly zones’ where concentrations of ash are “at levels unsafe for flights to take place”, but the CAA noted these are “very much smaller than the present restrictions”.
The CAA stated the way forward is based on international data and evidence from previous volcanic ash incidents, new data collected from test flights and additional analysis from manufacturers over the past few days, adding “it is a conservative model allowing a significant buffer on top of the level the experts feel may pose a risk”.
The CAA issued the following statement:
“The CAA has drawn together many of the world’s top aviation engineers and experts to find a way to tackle this immense challenge, unknown in the UK and Europe in living memory. Current international procedures recommend avoiding volcano ash at all times. In this case owing to the magnitude of the ash cloud, its position over Europe and the static weather conditions most of the EU airspace had to close and aircraft could not be physically routed around the problem area as there was no space to do so. We had to ensure, in a situation without precedent, that decisions made were based on a thorough gathering of data and analysis by experts. This evidence based approach helped to validate a new standard that is now being adopted across Europe.
“The major barrier to resuming flight has been understanding tolerance levels of aircraft to ash. Manufacturers have now agreed increased tolerance levels in low ash density areas.”
Engine manufacturers and other suppliers to avoid liability?
Establishing who is liable for the hordes of compensation claims which will inevitably arise is going to be a goldmine for lawyers.
There are for example reports aero engine manufacturers have threatened they will withdraw warranties if airlines fly through an ‘ash cloud’. This would put the onus on governments to underwrite the cost.
In addition, the CAA’s Revised Airspace Guidance requires airlines to:
– Conduct their own risk assessment and develop operational procedures to address any remaining risks;
– Put in place an intensive maintenance ash damage inspection before and after each flight; and
– Report any ash related incidents to a reporting scheme run by the CAA.
As every announcement is being made, the respective legal teams will be carefully vetting their own organisation’s legal position.
Given the inherent risk-averse nature of legal advice, these uncertainty factors could continue to cause service disruption, as airlines, manufacturers, governments and quasi-government bodies review their positions with their insurers.
NATS resumes UK airspace operations
In response to the CAA notice, British air navigation services provider, NATS, noted that most restrictions on UK airspace began to be lifted last night, with air traffic control services resuming in the UK, with the exception of an area over the north west of Scotland which continues to be affected by a dense concentration of volcanic ash.
But NATS warned the situation continues to be dynamic as a result of changing weather conditions and the prediction of dense areas of volcanic ash.
NATS stated, “this brings to an end a period of disruption and uncertainty for air passengers. Our operation is fully staffed and already responding to the backlog of flights entering UK airspace. We will be working with the airlines and airports to resume normal operations as soon as possible”. It added it would take some time for flights to resume normal operations.
Improvements in European movements
EUROCONTROL stated roughly 13,000 flights took place on April 20th in Europe, still well down on normal levels for a Tuesday of around 28,000. EUROCONTROL advises that all European airspace is available, with the exception of Finland which is closed at all levels.
Almost 75% of the total continent area is free of any restrictions. This area includes: Austria, the Balkan area, Belgium, Bulgaria, Czech Republic, Hungary, Italy, southern France, Greece, the Netherlands, Norway, Poland, Portugal, Spain, Romania, northern Sweden, Switzerland, Turkey, Ukraine.
Air traffic control services are not being provided to civil aircraft in significant parts of the lower airspace primarily in north-western Europe, including Denmark, Estonia, Ireland, Latvia, Sweden and the UK.
Air traffic control services are being provided albeit with very significant restrictions on the number of flights authorised, and/or the routes and flight procedures to be followed, in several parts of the lower airspace in north-western Europe, including Germany and northern France.
European aviation shares bounce back
European airline, airport and supplier stocks bounced back yesterday, suggesting investors believe they were oversold on Friday and Monday, but uncertainty remains. LCC Norwegian (+5.4%), led the way yesterday, while nordic rival SAS was 4.2% higher. Spanish LCC, Vueling, advanced 3.4%, while Air France-KLM, British Airways and Lufthansa all reversed losses from the day before, rising 0.7%, 1.0% and 1.8%, respectively.
