Emergency Signal
An emergency signal is a distress call transmitted by a spacecraft or aircraft to request immediate assistance. Emergency signals can be transmitted through various means such as radio, satellite, or visual signals. The most common emergency signal used in space and astronautical engineering is the SOS signal, which consists of three dots, three dashes, and three dots in Morse code. Emergency signals are used in situations such as spacecraft malfunction, medical emergencies, or unexpected events that require immediate assistance. It is crucial for spacecraft and aircraft to have reliable emergency signal systems to ensure the safety of the crew and passengers.
