Angle of attack is the angle between the wing chord line and the oncoming airflow, measured in degrees; it is a key aerodynamic parameter rather than a direct measure of aircraft attitude. In flight manuals, flight training documentation, and flight control system descriptions, the term appears in aerodynamics discussions, stall awareness, approach speed guidance, and performance planning to explain how lift and stall margins change with load and configuration.
In localization, angle of attack appears in flight training courses, stall recovery procedures, flight manual performance sections, and avionics descriptions for stall warning or fly-by-wire systems. It also occurs in accident investigation reports and simulator software. Translators must distinguish angle of attack from pitch attitude, especially in pilot-facing text where confusing the two can affect stall recovery understanding.
A common error is translating angle of attack as "攻角" with military connotations when the text is civil aviation, or as "俯仰角" and "仰角" in pilot documentation. Angle of attack is not the same as pitch attitude or climb angle. This confusion can distort stall warning information, flight manual limitations, and training content.
EASA and CE certification impose language requirements on maintenance and safety documentation. These terms carry airworthiness and liability implications, so they are rendered against the governing standard rather than translated freely.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
