How should the ACS or PTS be regarded by flight instructors?

The Airman Certification Standards (ACS) or Practical Test Standards (PTS) should be regarded primarily as testing documents. These standards outline the acceptable levels of performance that a student needs to achieve in order to provide a consistent and objective measure of their skills and knowledge during flight tests. Flight instructors use these documents to prepare students for the practical tests necessary for certification, ensuring that students are aware of the specific skills and knowledge areas that will be evaluated.

By understanding the ACS or PTS as testing documents, instructors can better communicate the expectations for pilot performance when students take their practical exams. This helps ensure that the training provided aligns closely with the standards required for certification, ultimately aiming to uphold aviation safety and proficiency.
