👉 The term "misspeed" refers to a specific speed measurement that is often used in navigation or aviation. Missspeed is defined as the difference between the actual speed of an aircraft and its maximum safe speed, which is typically around 100 km/h for air traffic control purposes. This means that if you were to fly at this speed, you would be considered low on your altitude and could potentially cause a collision with other aircraft or objects in the airspace.
