How many red cords visible indicate that aircrew should not accept an aircraft?

The indication that aircrew should not accept an aircraft is specifically determined by the visibility of red cords. If any red cord is visible, this serves as a clear warning that there is an issue requiring attention prior to accepting the aircraft. The presence of even a single red cord signifies that the aircraft is not in a condition suitable for operation, thus mandating that aircrew take this seriously and refrain from accepting the aircraft until the issue is resolved.

It's important for aircrew to be vigilant about these safety indicators to ensure they are operating under the safest conditions possible. The existence of red cords is a critical part of maintaining operational safety and upholding the standards of the aircraft acceptance process.
