These safety devices, typically made of brightly colored, durable fabric like nylon, are attached to critical components of aircraft, such as pitot tubes, control locks, and engine covers, that must be removed before flight. They serve as a highly visible reminder to ground crews and pilots of these crucial pre-flight steps. A typical example consists of a short length of red webbing with the warning text embroidered in white.
Their prominent role in aviation safety stems from preventing potentially catastrophic accidents caused by overlooked components. Historically, incidents attributed to such oversights underscored the need for a simple yet effective system. These warning devices offer a fail-safe, minimizing human error and enhancing procedural adherence. This straightforward approach significantly contributes to flight safety, protecting both crew and passengers.
