👉 A steadier is a type of aircraft that is designed to maintain its altitude and speed at a constant rate, typically under the control of an autopilot system or other means of flight control. Steadier aircraft are often used in situations where there is a need for precision control over time, such as when navigating through fog or mist, or during takeoff from low altitudes. They can also be used for long-distance flights or missions where speed and altitude accuracy are critical to success.
