Definition
The defined performance criteria — drawn from the Practical Test Standards, Airman Certification Standards, FAA handbooks, or the published lesson objectives — against which a learner's knowledge, skill, or maneuver is judged acceptable or unacceptable.
Plain English
The fixed yardstick a flight instructor measures the learner against. It's not the instructor's personal opinion of 'good enough' — it's the written criteria that say what counts as a pass.
Context Anchor
Seen in flight instruction when an instructor evaluates a learner’s performance during a lesson, practice flight, or stage check.
Derivation
Established comes from older words meaning “made firm” or “set up.” Standard came to mean an accepted measure used for comparison. Together, established standards means measures that have already been set, not something invented after the learner performs.
Why Pilots Care
Ensures consistent safety and proficiency across all pilots by providing clear, non-negotiable targets for training completion and certification.
Intuition Check
Do not read established standards as “whatever the instructor feels is good enough.” In this context, it means clear performance requirements that already exist and can be applied consistently.
Example Sentence 1
The instructor compared the learner's steep turns against the established standards in the ACS before signing off the lesson.
Example Sentence 2
By consistently meeting established standards, the student pilot progressed safely through each phase of training.
