Morse code is often used in which field today?

Morse code is primarily used in aviation due to its significance in communication, especially in the context of navigation and flight safety. In aviation, Morse code is commonly associated with radio navigation aids, such as VOR (VHF Omnidirectional Range) stations, which transmit their identification in Morse code. Pilots and air traffic controllers utilize Morse code to confirm they are receiving signals from navigational beacons, enhancing situational awareness and safety during flights. This is particularly crucial in poor visibility conditions or during instrument flight rules (IFR) operations.

While Morse code has historical significance and some niche applications in other fields, its practical usage has largely diminished with advancements in technology. In education, it may be taught as a historical communication method, and in computer programming or medical coding, there are alternative systems in place that are more efficient and widely adopted. Therefore, aviation remains the most relevant field today where Morse code continues to serve a specific and vital purpose.
