What action is required if flap asymmetry occurs during flight?

When flap asymmetry occurs during flight, it indicates an issue that could affect the aircraft's aerodynamic performance and stability. In response to such situations, following the abnormal procedures checklist is essential. This checklist provides specific guidelines tailored to address and mitigate the risks associated with flap asymmetry.

These procedures are designed to ensure the safety of both the aircraft and its occupants by outlining the necessary steps to stabilize the aircraft's flight characteristics, assess the severity of the issue, and determine if further action, such as an emergency landing, is required. The abnormal procedures checklist often includes steps for diagnosing the problem, adjusting settings, or preparing for landing if necessary.

Meanwhile, the other actions would not adequately address the risks posed by flap asymmetry. Continuing to fly at normal speed could exacerbate the situation or lead to loss of control. Following emergency landing protocols might be premature without first assessing the issue through the checklist. Attempting to reset the flaps without following the proper procedures could lead to further complications or worsen the malfunction. Thus, utilizing the abnormal procedures checklist is the most prudent and correct response in this scenario.
