A question is asked from Japan.
We operation the helicopter (EC135) in Japan.
Since there is only zone of Eurocontrol, Safety Information Notice which EC135 manufacturer's Eurocopter took out should teach it.
The Meteorological Agency of Japan Aviation color code is not use.
Is Aviation color code of Eurocontrol and ICAO(USSG) unified?
As for Eurocontrol, zone 1:black zone, zone 2:red zone, and ICAO (USSG) are green, yellow, orange, and red.
To what is the definition about zone1 and zone2 of Eurocontrol specified?
Best Regards.

(SUMMARY)
Due to the eruption of the volcano in Iceland EUROCOPTER has been contacted by many operators asking for
advice on how to proceed with their operation under these circumstances.
Flying in an atmosphere containing volcanic ash may affect the behaviour of the helicopter. Depending to the
variety of the particles (size, weight, density, chemical composition…) it may increase the probability of a partial
power loss, engine flame out, navigation and piloting instruments failure or other helicopter malfunctions. Flight in
such conditions may also decrease visibility and accelerate erosion of certain helicopter parts. In the past, on EC
helicopters, engine flame outs have been experienced after flight through industrial smoke.
As a consequence EUROCOPTER advises operators to avoid flight in area of high density volcanic ash
contamination (named zone 1 or black zone).
