Signalfjädrar

Signalfjädrar, also known as signal flags or signal pennants, are a system of visual signaling used primarily in maritime and aviation contexts. They are designed to convey specific messages or warnings to other vessels or aircraft. Signal flags are typically made of fabric and are hoisted on a flagpole or mast. Each flag has a unique shape, color, or combination thereof that represents a particular letter, number, or symbol.

In maritime signaling, signal flags are used to communicate a wide range of messages, from distress signals to navigational warnings. For example, the international distress signal is a red flag with a white diagonal stripe, while a red flag with a white square is used to indicate that a vessel is aground. Signal flags are also used in aviation to convey messages such as "clear for takeoff" or "clear for landing."

Signal flags are an important tool for ensuring the safety and efficiency of maritime and aviation operations. They provide a clear and unambiguous means of communication, even in situations where verbal communication may be difficult or impossible. However, the use of signal flags requires training and practice to ensure that signals are correctly interpreted and responded to.
