Private Pilot Airman Certification Standards Airplane FAA-S-ACS-6B, June 2018. High quality reprint by Elite Aviation Solutions. Part of our EAS Airman Certification Series. For Airplane Single- and Multi-Engine Land and Sea. The Federal Aviation Administration (FAA) has published the Private Pilot - Airplane Airman Certification Standards (ACS) document to communicate the aeronautical knowledge, risk management, and flight proficiency standards for the private pilot certification in the airplane category, single-engine land and sea; and multiengine land and sea classes. This ACS incorporates and supersedes FAA-S-ACS-6A, Private Pilot - Airplane Airman Certification Standards, Change 1. The FAA views the ACS as the foundation of its transition to a more integrated and systematic approach to airman certification. The ACS is part of the safety management system (SMS) framework that the FAA uses to mitigate risks associated with airman certification training and testing.
