Initial response

Response from: Civil Aviation Safety Authority
Action status: Closed - Accepted
Response text:

The following response dated 22 March 2003 was received from the Civil Aviation Safety Authority:

Although the Authority acknowledges the intent of this recommendation, the Authority believes that the Bureau of Meteorology (BoM) is the agency currently responsible for the standards of aviation meteorology. The lead in changing such standards rests with the BoM but the Authority would be pleased to cooperate in a project to develop a standards scale of describing thunderstorm activity.

However, the Authority's view is that grading of thunderstorms would further obfuscate the matter, as all thunderstorms are 'bad" and should be avoided. Grading of thunderstorms merely provides criteria to permit flight through some thunderstorms and mandatory avoidance of others.
