Full Definition

In aviation, professionalism is the consistent practice of conducting oneself to the standards expected of a competent, responsible pilot — applying knowledge, skill, judgment, discipline, and ethics to every flight regardless of who is watching, how routine the task feels, or whether the pilot is being paid.

Context Anchor

Derivation

From the Latin 'profiteri' meaning 'to declare publicly' — the of 'profess' and 'profession.' A professional was originally someone who publicly declared a commitment to a set of standards. In aviation, the word keeps that flavor: a professional pilot has, in , committed to flying by certain standards every time.
