Zen Air uses the ARGUS CHEQ (Charter Evaluation and Qualification) program which was developed over a decade ago as the most accurate and detailed third-party aircraft safety due diligence system for charter operators, buyers and passengers around the world.

ARGUS extracts, filters, and vets data on operators around the world through the CHEQ Program. To score the gathered data, ARGUS uses a proprietary algorithm that has formed the foundation of the only safety rating system in the business jet charter marketplace. This scoring system, that is the backbone of CHEQ, provides aviation charter buyers with an independent, third-party, factually-based rating on an operator’s actual safety history.
