Before a Flight Control Function (FCF), what must QA ensure is conducted?

For a Flight Control Function (FCF) to proceed safely and effectively, QA (Quality Assurance) must ensure that pilots and aircrew are fully briefed on the flight's purpose. This briefing is crucial because it provides the crew with vital information about the objectives, parameters, and any specific considerations related to the FCF. Understanding the purpose of the flight helps the aircrew to know what to focus on, anticipate the maneuvers needed, and identify any potential risks associated with those functions.

Effective communication and understanding among the flight crew contribute significantly to flight safety and operational success. Through a proper briefing, the pilots can align their expectations and operational strategies concerning the test, ensuring that any necessary adjustments can be made before taking off. This step is essential in maintaining a high level of readiness and awareness during the FCF.

While other options may be important aspects of preparation for flight, they do not directly address the specific requirement for crew understanding and readiness regarding the flight's purpose. Thus, ensuring that the aircrew is well briefed takes precedence in the context of an FCF.
