2010/20 Info Alert: Volcanic Hazards and Aviation Safety

The CAA would like to share with aerodrome operators an article published by the Flight Safety Foundation in May 1993 entitled "Volcanic Hazards and Aviation Safety: Lessons of the Past Decade", which contains useful background information on the hazards of ash-laden clouds from a volcano.

In particular the chapter entitled "Aircraft Also Face On-ground Ash Hazards" starting on page 5 gives information on the hazards that occur when ash falls to the ground (as a result of various weather conditions) and covers runways and taxiways. Aerodrome operators may find this information helpful and may wish to consider in advance options for clearing aerodrome surfaces of ash should this become necessary.
