Airman Certification Standards (ACS)

The Airman Certification Standards represent the FAA's adoption of a competency-based evaluation framework for pilot certification, replacing the earlier Practical Test Standards (PTS) system that had governed checkrides since the 1970s. The PTS evaluated applicants primarily on observable flight skills (the manipulative stick-and-rudder tasks), with knowledge tested separately and only through the written Aeronautical Knowledge Test (AKT). Risk management — arguably the most safety-critical cognitive skill for single-pilot operations — was not explicitly tested or graded in the PTS framework. The National Transportation Safety Board, the General Aviation Joint Steering Committee (GAJSC), and the broader aviation community recognized this gap and recommended a more integrated evaluation approach, which the FAA implemented through the ACS project.

The Private Pilot Airplane ACS (FAA-S-ACS-6) was published in June 2016 as the first ACS document, followed progressively by the Instrument Rating Airplane ACS (FAA-S-ACS-8, 2016), the Commercial Pilot Airplane ACS (FAA-S-ACS-7, 2017), the Flight Instructor for Airplane (CFI) ACS (FAA-S-ACS-25, 2019), the ATP ACS (FAA-S-ACS-11, 2018), and additional ACS documents for helicopters, gliders, sport pilots, and other categories. The FAA updates each ACS document periodically; current versions are published on the FAA website and supersede all prior versions. Designated Pilot Examiners (DPEs) and Flight Standards District Office (FSDO) examiners are required to conduct practical tests using the current ACS version at the time of the test.

Each ACS is structured in a consistent hierarchy: Areas of Operation (the major phases of flight and ground evaluation, such as Preflight Preparation, Airport and Seaplane Base Operations, Takeoffs and Climbs, etc.) contain Tasks (specific maneuvers or evaluation points within each Area). Each Task contains three mandatory element types that the examiner must assess:

(1) Knowledge (K) elements — the specific facts, concepts, and aeronautical information the applicant must be able to explain or discuss. These elements bridge the written test and the oral examination conducted before the flight portion of the practical test.

(2) Risk Management (R) elements — the judgment-based factors the applicant must identify and mitigate. Risk Management elements are explicit: for a cross-country flight task, for example, R elements include things like "risk associated with flight planning errors" and "risks associated with deteriorating meteorological conditions." An applicant who cannot articulate appropriate risk mitigations for these elements fails the Task even if the flight skills were acceptable.

(3) Skill (S) elements — the performance standards for the observable flight maneuver, including tolerances (e.g., maintain altitude ±100 feet, heading ±10 degrees). These are inherited largely from the superseded PTS standards.

The ACS is broadly analogous in intent to EASA's Competency-Based Training and Assessment (CBTA) framework under EASA Part-FCL and AMC1 FCL.900, though the structural implementation differs. EASA CBTA defines nine Core Competencies (Application of Procedures, Communication, Aircraft Flight Path Management — Automation, Aircraft Flight Path Management — Manual, Leadership and Teamwork, Problem Solving and Decision Making, Situation Awareness, Workload Management, and Knowledge) and requires observable behavioral indicators (OBIs) for each, going further than the ACS in formalizing crew-level competencies for multi-crew professional operations.

For flight instructors, the shift from PTS to ACS changed lesson planning significantly. Under the PTS, an instructor could prepare a student for the checkride by drilling the flight maneuvers listed in the PTS and relying on the written test to cover knowledge. Under the ACS, the instructor must actively integrate risk management discussion into each lesson — introducing the Risk Management elements for each Area of Operation as those tasks are taught, not as a last-minute ground session before the checkride. Examiners report that Risk Management is now the most common basis for practical test failures among new private pilot applicants, underscoring how significant this shift was.

For training managers and chief flight instructors, the ACS provides a ready-made competency checklist that can be used as the basis for a structured training syllabus. Each ACS Task can be mapped to one or more lesson plans, and student readiness for the checkride can be evaluated against the specific Knowledge, Risk Management, and Skill elements rather than a general impression of readiness. Schools that align their training record system to the ACS task structure can track task-level completion and flag outstanding elements — rather than only tracking hours flown — giving students and instructors a clearer picture of checkride preparedness.

Aviatize's training management module supports ACS-aligned syllabus structures: training managers can build lesson plans and stage-completion records that map directly to the ACS Areas of Operation and Tasks for each certificate or rating. When an instructor logs a lesson, they can record which ACS Tasks were introduced, practiced, or signed off, building a task-level competency record that goes beyond simple flight hours. This record is available to both the student (so they can see which Risk Management and Knowledge elements remain outstanding) and to the chief flight instructor (for stage check authorization and checkride readiness determination).

For compliance auditing, Aviatize generates ACS task completion reports that show, for any given student, what percentage of Knowledge, Risk Management, and Skill elements have been logged across all Areas of Operation. This report is the primary document a DPE relies on when reviewing a student's training record before a practical test — and having it in a standardized, exportable format saves both the school and the examiner time at the checkride. When the FAA updates an ACS document, the training manager updates the relevant syllabus template in Aviatize and the system flags any enrolled students whose training record needs to be reviewed against the new requirements.
