It seems the oh so brief period of the ash abating is coming to an end, and the danger of variability is back.
NATS seem to be opening more airspace (though not as far as LHR/LGW/LCY), but with the additional ash, personally, I’d expect to be looking at closing the airspace again sooner rather than later.
The joy of mother nature. I just wish the news improved.
NATS statement below at 02:45.
Since our last statement at 2100 yesterday, the volcano eruption in Iceland has strengthened and a new ash cloud is spreading south and east towards the UK. This demonstrates the dynamic and rapidly changing conditions in which we are working.
Latest information from the Met Office shows that the situation is variable. The information shows that Scottish airports should be available from 0700 and more airspace over England may become available from 1300 although not as far south as the main London airports.
We will continue to monitor Met Office information and the situation is likely to change during the course of the day. We will make a further statement at approximately 0900 (local time), today, Tuesday 20 April.
NATS is maintaining close dialogue with the Met Office and with the UK’s safety regulator, the CAA, in respect of the international civil aviation policy we follow in applying restrictions to use of airspace.
We are working closely with Government, airports and airlines, and airframe and aero engine manufacturers to get a better understanding of the effects of the ash cloud and to seek solutions.
