Final answer:
When a spoiler panel fails in the non-retracted position, the Flight Control SD page would show an abnormal color indication for the affected spoiler, possibly accompanied by a fault message or code. Pilots can consult the aircraft's manual or QRH for procedures for managing the situation, which can affect the aircraft's aerodynamics.
Step-by-step explanation:
If a spoiler panel failed in the non-retracted position on an aircraft, the Flight Control Synoptic Display (SD) page would generally show an indication of this failure. On most modern aircraft with advanced avionics, such as those equipped with Electronic Flight Instrument Systems (EFIS), the Flight Control SD page provides a graphical representation of the aircraft's control surfaces, including the spoilers.
When a spoiler panel is stuck in the non-retracted position, the display will typically indicate this by changing the color of the affected spoiler panel to represent an abnormal condition, which could be amber or red, depending on the severity of the situation. Additionally, there might be a textual message or an alphanumeric code that specifies the nature of the fault. This alert allows the flight crew to quickly identify which spoiler panel is affected and take appropriate action as required by their checklists and procedures.
The aircraft's manual or a quick reference handbook (QRH) typically provides specific instructions on how to respond to such indications. However, this can have an impact on the aircraft's aerodynamics, potentially affecting roll control and lift dumping during landing. Therefore, pilots must exercise caution and adhere strictly to standard operating procedures when dealing with such malfunctions.
