Atmospheric corrosivity at 25 airbases and airports in Australia, and 71 overseas airbases and airports, has been measured directly using CLIMAT test samples or predicted using algorithms developed at DSTO. The atmospheric corrosivity at each location is classified as negligible, moderate, moderately severe, severe or very severe. These results will assist aircraft fleet operators to prioritise rinse, wash and maintenance schedules for ADF aircraft based on the time each aircraft has served in the various location corrosivity classifications. Aircraft spending significant time in locations near or at the upper end of atmospheric corrosivity severity can be given preference, if possible, when scheduling rinse, wash and maintenance operations
