We have an "Airman-certification" tag, but with the new distinction of the old "Practical Test Standards" currently being phased out, and the new "Airman Certification Standards" which seem to be raising more than a few questions in the aviation community an "Airman-Certification-Standards" tag would seem to me as a good idea because now we really have three topics:
General certification questions about experience, training, and flight time totals to qualify and other such bureaucratically-based questions.
Questions about the PTS.
Questions about the ACS.
Should we have a new tag for this?
