ARGUS is a global leader in performing on-site safety audits for corporate flight departments, charter operators, and commercial airlines with the objective of managing risk. ARGUS services include a system of safety rankings. To achieve the Platinum Rating awarded to Presidential Aviation, ARGUS conducts in-depth research and audits. Historical information on the operating certificate, pilots, aircraft serial numbers, ownership, management and financial data is compiled, processed and scored with respect to safety. An operator with an ARGUS Platinum Rating exceeds the median scores for safety out of an aggregate group of operators with like exposures.
