Aircraft are being checked for ash damage to their engines before every take-off and after every landing at UK airports as part of increased safety measures.
The Civil Aviation Authority (CAA) has issued new safety guidelines to all airlines outlining extra safety checks, despite reopening skies for commercial flights, according to the Independent.
The CAA and air traffic control services allowed flights after engine manufacturers informed them engine tolerance to volcanic ash could be increased from zero to a very low level.
National Air Traffic Services strategy and investment general manager Alex Bristol said the CAA had been presented with scientifically backed evidence rather than one or two undamaged flights showing the previous criteria had been erring too far on the side of caution.
Bristol said there had been some reports of increased wear and tear on aircraft but it is more likely to shorten the lifespan than cause problems during flight.
